Title: CDT-10
Post by: Westerwälder on 21 Dec 2018, 05:55 pm
I hear news about a cdt-10. is that true? What is there to report? Does it differ only by the design, or is it for me (at the moment cdt-8) a recommendation?
Title: Re: CDT-10
Post by: rustydoglim on 21 Dec 2018, 06:51 pm
Yes, it is expected to ship sometime late January, and we will provide more info after the holidays.

No, it will not play SACD, which requires different transport than CD.
The estimated ship date is Feb. 2019

Will it replace the CDT-8 Pro?  Will it still have I2S output (that matches the one in the CDT-8 Pro)?
Title: Re: CDT-10
Post by: rustydoglim on 19 Mar 2019, 06:01 pm
No, CDT-10 is part of the "10 series", so performance wise shoud be better than CDT-8 Pro.  I think it should be shipping within 2 to 3 weeks, I will have more info when I hear from the factory.  The last I heard was that R&D is working on firmeware (that's the code that control the functions). I think the ability to select tracks is also added. 
I don't know the price yet, you can expect whatever it is, it will be exceptional value for money from NuPrime.

Post by: Westerwälder on 20 Mar 2019, 05:49 pm
I would have been very surprised if a new device from Nuprime differs only in appearance. I'm looking forward to what we get offered here now. Concerning the 10 series, I would like the remote control of the CDt8 despite the design. We are surprised. In anticipation and a little impatient. (Google translator)

Dear Westerwälder!

My name is Gerhard, I am from Austria and I am highly interested in the Nuprime CDT 8 or CD 10T. You wrote in another thread that you originally owned a Pro ject CD Box RS 8 but you preferred a CDT 8. That sounds great.  Are you  satisfied with the CD 8 and is is reliable)

In a review to which nuprime on its homepgae has linked it is written: "In addition to the slow (but not that bad) operating interface, my only real complaint is the CD drawer is very loose and saggy, and the depression that holds your CD is very shallow. So when you hit "retract" sometimes the CD jumps out of its holder and jams the drawer open. This freaks out the Nuprime and you will need to cycle the power to get it working again." Have you made the same experience ?

As Nuprime is not distributed in Austria, can you recommend to me a dealer in Germany. Thank you very much!

Kind regards!

Thank you very much for your feedback!

Dear Westerwälder!

Thank you very much for your feedback. Most important to me: Are you still satiesfied with the CDT 8 ? ("Bist Du noch immer zufrieden mit dem Player?")

Thank you also very much to name me your dealer! (I write in english so that the other users can understand whar I am writing and furthermore my post have to be approved.)

What are the conditions to write a pm , I have not found it on the pages of AC ( a certain amount of posts?) ?

Hello Gerhard,
I have just sent you a message. "Jr. Member" and it is not a problem.
I am very satisfied with the CDT8. The problem with the drawer I had the first time I run the player.
That was my own fault. If you consider the correct seat of the CD, it is no longer an issue.
I could compare the CDT8 with the ProJect CD Box RS. I sold them quickly.
I have to say, I have been operating the amplifier combination DAC10 and ST10 for some time now.
Likewise, the speakers S6 from the House Rowen.
Everything at my hifi consultant tasted and felt very good.
The NuPrime products are hard to beat in their respective class. So far there was no product that
could approach this class of rendering. I will also get the CDT10 unheard as soon as it is available here.
I can recommend the CDT8 without restriction. I have known my hifi consultant for 40 years and we have seen and heard many things together.
But nothing had the class of NuPrime devices.

Post by: rustydoglim on 29 Mar 2019, 07:52 am
CDT-10 can only ship mid May.  Unfortunately the firmware takes more time to change and debug.
What's the difference between CDT-10 and CDT-8 ?
1. There are more mechanical enhancement for long term reliability as well as aesthetic.
2. Power related circuit has been upgraded, mainly to further reduce noise.
3. Improved remote control for track selection.

Our recommendation:
1. If you are in the market to purchase JUST a CDT to go with your existing system, CDT-8 offers the better value for money. The performance of CDT-8 is very close to CDT-10.
2. But if you are looking for a highly resolved and exceptional system, then go for the whole 10 series.

CDT-10 is likely to cost at least $1495.  Actually at this price for its performance it is exceptional.  It is only because CDT-8 makes it look "expensive".  High-end audio is no longer expensive compare to other cash draining devices and hobbies. I have drawer full of tablets, phones and useless gadgets. My online gaming pals drop a few hundred $ in a week (it took me 2 years to get to level 78 on War Commander Rogue Assault  :duh:).

Sorry, I didn't find what is inside of 8 Pro Transport.
Title: Re: CDT-10
Post by: Samoyed on 4 Apr 2019, 09:09 pm
Well, at first it was believed to be a Phillips transport, but, apparently, it is just driven by a Phillips chip. I’d like to know what transport is in my cdt 8 pro, too. 😿
Title: Re: CDT-10
Post by: Eduardo AAVM on 5 Apr 2019, 04:59 am
Well, even more than knowing the manufacturer of the transport one very interesting thing about it is that NuPrime transports play discs in CAV constant angular velocity mode, if I understood right this "transport’s single speed", as opposite of CLV constant linear velocity. I remember that in teh old days, with Laserdisc the best image and sound came from those disc to be played in CAV mode, really I am waiting dearly for CDT-10
Title: Re: CDT-10
Post by: Samoyed on 5 Apr 2019, 11:46 am
Well, I can tell you my 8 is a little jewel, but since I bought an Innuos network streamer, which incorporates a cd transport, I seldom use it.
Title: Re: CDT-10
Post by: JLM on 5 Apr 2019, 01:27 pm
Gave up on my interest in the CDT-8 Pro after procuring a fully loaded Mac Mini.

Curious Samoyed, what is your DAC?  I have a PS Audio DirectStream Junior and was planning on using the I2S feature of the CDT-8 Pro, which I understand would give superlative performance.  But didn't want both CDT and server and was never sure I wanted to sacrifice convenience, access to web based music, and access to hi-res music to go with the CDT.  The attraction of the CDT was getting out from under all the computer confusion/hassles (which I'm still suffering from and probably will the rest of my life). 
Title: Re: CDT-10
Post by: Samoyed on 5 Apr 2019, 03:23 pm
Evolution DAC: lovely sound. I’m all digital now, and my Innuous music server sounds great through the DAC.

My evolution began making some odd noises over time. Other than the odd noise, which Nuprime claims is solely related to user error, or turn on, off sequence, I love it. I use 12s to connect the 8.
Title: Re: CDT-10
Post by: rustydoglim on 5 Apr 2019, 10:37 pm
I checked with our chief engineer about turn on noise regarding Evo DAC (or any other model). Recently we have one case with a customer's IDA-16, also during power on.
During the split second of power on, as hundreds of parts are being supplied with power (that goes from 0 to its operating voltage), this behavior is hard to determine, and might change slightly over time. Typically it is due to slight DC offset on the output during this split second. For power amp we typically add relay, but not on Evo DAC.
This is not an user error (If I have ever implied, it was my mistake in communication).  A small turn on noise is an expected  behavioir and will not affect performance or speaker. Obviously if it is a loud pop, that will be a problem. 
Title: Re: CDT-10
Post by: Samoyed on 5 Apr 2019, 10:39 pm

Title: Re: CDT-10
Post by: JackD on 6 Apr 2019, 01:31 am
If you turn your DAC on and off buy the remote or front switch with the amp powered up you will hear the pop as I do with the DAC-10.  The other noise may be amp dependent.  Just leave the DAC fully powered up all the time.

JLM, my understanding is that the Nuprime I2S is compatible with Nuprime products only, having previously inquired about I2S compatibility between PS Audio Memory Player and Nuprime Evo DAC.
Title: Re: CDT-10
Post by: JackD on 7 Apr 2019, 02:02 am
The Nuprime I2S is compatible with the PSA standard as I'm doing it as are several others on the PSA forum. Also applies to W4S DAC's. Both companies provide their I2S wiring diagrams on their websites.
Title: Re: CDT-10
Post by: rustydoglim on 7 Apr 2019, 10:45 am
Since i2s over HDMI port is not an industry standard, so we can not officially state that we support other brands.
It is up to users to compare the i2s as published on our website. 
Please make sure they are exactly the same when comparing the spec with another brand. If you find just 1 pin with different spec out of all the pins, you can't gamble that it will work.

John - I have a CDT-8 Pro. I saw a reference to a CDT Pro-8 at the Pro-ject RS2 T site ( https://www.project-audio.com/en/product/cd-box-rs2-t/ ) and they mentioned this (bold emphasis mine):

"Being based in Vienna, we are lucky enough that Philips had its development department here, and many CD players and mechanisms were designed here. The gentlemen who were part of this epochal invention are still around, formed in a company called StreamUnlimited. We are proud to say, the pope of the CD player today – Mr. Michael Jirousek, was helping to create this ultimate CD player.
The CD Box RS2 T is the latest development in our line of ultimate top-loading CD transports, built around the StreamUnlimited CD mechanism CD–Pro 8 and servo system CD-84. The CD Box RS2 T takes playing standard Red Book Audio CDs to perfection.
The CD Pro-8 has the servo system directly integrated in its aluminium body. The entire body is suspended on a proprietary anti-vibration system, which allows us to control the level of outside vibrations reaching the insides of the device. The CD mechanism is stabilized and secured, unaffected by external influences."


Is the CD transport in my CDT-8 Pro the same one as mentioned in the Pro-ject snippet above (i.e., is it a StreamUnlimited CD mechanism)? And also which CD mechanism is in the CDT-10? Thanks

Hi,
my experiences with project are limited.
https://www.audiocircle.com/index.php?topic=158771.0
The promises were high, but failed because the project drive did not live up to Project's promise.
In my case, that meant 3 times reclamation.
3x project CD box. Threadbare excuses. Manufacturing in Eastern Europe, software problems, etc.
My decision: CDT 8
And since that the best sound ever.

For there is only one increase.
The CDT 10.
But I do not want to judge rashly.
Title: Re: CDT-10
Post by: rustydoglim on 17 Oct 2019, 09:25 pm
I got more information about CDT-10 versus CDT-8 Pro, and just updated the website.

CDT-10 extends the exceptional digital design of CDT-8 Pro with enhanced AC noise filter (inherited from Evolution DAC) and power circuit. But to be considered as the ultimate CD transport, CDT-10 design philosophy is to minimize every possible mechanical vibration. The CDT-10 chassis design has similar structural integrity as a submarine (tubular structure with vertical & longitudinal rigidness) evenly distribute vibration. The transport mechanism is further sandwiched with aluminum plates to reduce vibration.

You will hear the difference.
Title: Re: CDT-10
Post by: Westerwälder on 28 Mar 2020, 05:48 pm
Today I had the opportunity to hear the CDT-10 extensively.
I have to say I'm thrilled.
Such a fine drawing of the smallest details, a calmness in the reproduction, which at the same time builds up a tension, more precisely marked bass with oscillation (double bass) Smallest details, which I had not previously noticed with the CDT-8.
The CDT-10 makes the music exciting.
A worthwhile increase.
I am attached.
Title: Re: CDT-10
Post by: rird on 28 Mar 2020, 07:02 pm
I had expected more control, more muscular, texture and better 3D rendering.
That would probably require another transport and a more massive build.
Like Wadia or perhaps Esoteric transports.
Title: Re: CDT-10
Post by: Westerwälder on 4 Apr 2021, 07:26 am
Since the beginning of March, the CDT-10 has replaced my CDT-8. I am more than happy.
The CDT-10 outperforms the CDT-8 in all respects.
I myself had no way of hearing the CDT-10 against more expensive CD drives.
My HiFi dealers told me the best price-performance ratio when I made the purchase decision.

The Nuprime I2S is compatible with the PSA standard as I'm doing it as are several others on the PSA forum.

I'm among that group, using the I2S connection on my PSA Stellar Gain Cell/DAC. Works perfectly as long as I don't choose a sampling rate higher than the Stellar can accept.

Running CDT-10 transport I2S output one week, using stock NuPrime PC / I2S cords, with my Denafrips Pontus II DAC. Works great; also, Pontus II accepts higher sampling rates than the CDT-10 outputs so no issues there.

StreamUnlimited is the high end ODM/OEM for many top brands and they designs are "not cheap" and world class. All I can say is that Nuprime's factory has collaborated with Michael Jirousek/Stream Unlimited for a long time, so we have some "cost advantage" :).
Whether it is CDT-8 Pro, CDT-9 or CDT-10, you are getting a good deal.

I don't know enough about the industry to say whether 200 units so far is reasonable or not, but from where I sit (which is very happily with a CDT-8 Pro), the price differential is large enough that I'm not surprised its sales would be some fraction of the 8's.

Right now I'm about to embark on a listening test of standard redbook discs played on my CDT-8 Pro at DSD 128 via I2S to the DAC in my PSA preamp, compared to the same discs played on my new Marantz SACD 30n, with its proprietary no-DAC-chip MMM conversion process, feeding analog to the PSA. I've only had the Marantz a week, and so far I've only played SACDs on it, but everyone says it works wonders on CDs. We'll see.

Would you share what 1) power cord, and 2) I2S (if you're using I2S) cables you are using with the DCDT-10? Thanks. FYI - never been to Soest; lived in Fernwald-Steinbach outside Gießen from 1988-1991.

2. Question is answered quickly. Since the DAC-10 does not have an i2s connection, I have no experience.
Regarding the question of cables in general, I have made the experience that mixed cabling is not optimal.
One cable gives, the other takes ...
That's why I equipped my system with cables from the same company.
I don't want to give a recommendation. With so many high-end cables there is a favorite for everyone.
After long listening comparisons, my first favorite was the Supra brand from Sweden.
In the meantime I have completely wired my system with Wireworld.

Some musings on the CDT-10.

I've been running the stock NuPrime CDT-10 power cable, and using a VH Audio cryoed Flavor 1 PC (designed for digital components) into my Denafrips Pontus II DAC with great sounding results. The other day I needed to hunt through my cable collection due to reconfiguring a video component, and stumbled across a beefy VH Audio cryoed Flavor 4 PC - unused and forgotten since I parted ways years ago with a mono amp pair. Great opportunity to hear what upgrading PCs would do for these two components, and I took advantage of my find: after cleaning the newly unearthed PC's connectors with Caig's Deoxit, and conditioning them with DeOxit Gold (used to be called ProGold), I swapped the VHF4 onto the Pontus II, the VHF1 onto the CDT-10, used the IsoTek burn-in cd for a few days, then gave a listen.

More positives to everything, which was not unexpected. The VHF1, designed for digital components, presents seemingly a pleasant synergy with the NuPrime CDT-10 unit and an increased performance over the stock cord. [FWIW, the Pontus II DAC boasts of its encapsulated linear power supply (which in part uses dual o-core transformers), so to me it's no surprise that those transformers / the power supply likes being fed by the beefier VHF4 (which is unshielded "in order to maintain unrestricted macro and micro dynamics".] Audio improvements were heard in, and not limited to: bass extension, macro/micro dynamics, soundstage height and depth, background blackness (even though it seemed pretty "black" before!), instrument placement (orchestral work proved so revealing), etc. Spinning the Cowboy Junkies' "The Trinity Session" proved a sublime experience.

Loving the extensive input section of the CDT-10, and I've used all of the following with good results: AES/EBU, coaxial, and I2S; the optical input remains, and will remain, unused. So far the CDT-10 sounds similar when using each input, yet I prefer using the I2S. As of yet I have not tried to sub out the CDT-10's stock I2S cable...yet. A very small CDT-10 nit - I wish the unit could show time remaining information for track / cd, maybe a future iteration will. The NuPrime CDT-10 is repeatedly proving to be a "sound" investment and a synergistic pairing with the the Pontus II DAC and my other system's gear, thanks NuPrime. The unit runs cool, looks good in black, operates noiselessly, and is pretty fully featured. YMMV

Happy listening!

Did you need to reconfigure the pins on the Pontus II for the I2s connection to work with the CDT-10?  I have a CDT-8 and Pontus II and wanted to try the I2s connection but wasn't sure what was needed.  Which I2s cable did you use?  Thanks in advance for any info.

SRO, I did not reconfigure the Pontus II's I2S connection because it seems that each of the unit's respective pinout configuration match. FYI - Denafrip's Pontus II manual includes a diagram with the Pontus' I2S pin configuration:

Here's the CDT-10 manual's diagram for its I2S pin configuration:
(https://www.audiocircle.com/image.php?id=227016)
Pinout items 1,3,4,6,7,9 for each unit seem to have the same setting, to me:
Maybe someone in the forum will chime in if they feel the Pontus II requires an I2S pinout reconfiguration. FYI - here's the Pontus II's video guide on how to reconfigure the DAC's I2S pinout settings (https://www.denafrips.com/config-pontus). Please let me know if you find that the Pontus II merits an I2S pinout reconfiguration. I'm open to making any improvement.

Which I2s cable did you use?  Thanks in advance for any info.

Still running the NuPrime stock I2S cable, per my comments:
Some musings on the CDT-10....
As of yet I have not tried to sub out the CDT-10's stock I2S cable...yet.

John - I have a CDT-8 Pro. I saw a reference to a CDT Pro-8 at the Pro-ject RS2 T site ( https://www.project-audio.com/en/product/cd-box-rs2-t/ ) and they mentioned this (bold emphasis mine):

"Being based in Vienna, we are lucky enough that Philips had its development department here, and many CD players and mechanisms were designed here. The gentlemen who were part of this epochal invention are still around, formed in a company called StreamUnlimited. We are proud to say, the pope of the CD player today – Mr. Michael Jirousek, was helping to create this ultimate CD player.
The CD Box RS2 T is the latest development in our line of ultimate top-loading CD transports, built around the StreamUnlimited CD mechanism CD–Pro 8 and servo system CD-84. The CD Box RS2 T takes playing standard Red Book Audio CDs to perfection.
The CD Pro-8 has the servo system directly integrated in its aluminium body. The entire body is suspended on a proprietary anti-vibration system, which allows us to control the level of outside vibrations reaching the insides of the device. The CD mechanism is stabilized and secured, unaffected by external influences."


Is the CD transport in my CDT-8 Pro the same one as mentioned in the Pro-ject snippet above (i.e., is it a StreamUnlimited CD mechanism)? And also which CD mechanism is in the CDT-10? Thanks

ANSWER:

StreamUnlimited is the high end ODM/OEM for many top brands and they designs are "not cheap" and world class. All I can say is that Nuprime's factory has collaborated with Michael Jirousek/Stream Unlimited for a long time, so we have some "cost advantage" :).
Whether it is CDT-8 Pro, CDT-9 or CDT-10, you are getting a good deal.
[please forgive my poor English]

Great.
But we would like to know exactly which CD drive NuPrime uses for the CDT-10: CD Pro-8, or something else (what?).
This should not be a company's secret, and should be disclosed.
I do not buy a €2350 CD transport without knowing what I'm buying, sorry (in English: I don't buy a pig in a poke  | in French: I don't buy a cat in a bag).

Secondly, is the CD mechanism totally silent at one arm's distance? (when playing music of course, NOT when skipping tracks, who cares about noise then?!)

Thanks.
Orfeo

Have to wait until factory open on Monday to find out.
