Title: CDT 8 Pro transport
Post by: Mr Peabody on 11 Jul 2018, 04:54 pm
I'm beginning to look into CD transports, wondering if anyone has compared the CDT8 to any other transports? 

Also any comment on the upsampling, sounds better, not much difference etc.  I'm assuming the various rates are selectable? 

I'm using a Hegel HD30 DAC.  I do stream Tidal now but not interested in a server at this point.

Thanks

 I compared the CDT-8 with my highly acclaimed Pro-Ject CD Box RS. This is now for a fraction of the purchase price for sale.

The CDT 8 is that much better that you are selling the CD Box RS?

I am interested because I have a Project CD Box RS.  Thanks for any information you can provide.

This may not help but I've used a PS Audio Perfectwave Memory player for some time before I sold it.
Streaming 100% now

Many positive reviews out there.

Something to think about....

here's one for $999 on Audiogon

The CDT 8 plays much more natural. Much better than the CD box. It's a clear thing for me. More spatiality, a good orangeability of the instruments. Voices are played back in their original form. Listening to music with the CDT 8 does not strain.

Does the sample rate conversion help with the sound? e.g. DSD or 384Khz
Title: Re: CDT 8 Pro transport

Sample rate conversion only makes the music sounded different, it will not add any details. The nice thing is that you can try it on-the-fly with the remote.

  There is nothing better than a dedicated transport for CD playback. Especially Redbook. Nice to have the sample rate conversion to play with.
  Have yet to hear CDT 8 however with Nuprimes reputation should be a VG product to at least try.

Thank you for the information.

This may sound silly, but do you find the remote (which doesn't have numerical buttons for direct track access) to be inconvenient?  I had a transport that had a similar remote and I found the track access inconvenient.  I was relieved to get the Pro-ject which had numerical/direct access buttons.

I know, but as a small manufacturer, making remote control is a major pain in the ass (hey, I will tell it like it is) problem. Supplier wants large order (1K or more), so we have to standardise the remote for many models (with some variations on the keys).
Most people don't need to keep jumping around from track to track (unless doing demo, but better to compile everything in one CD).

The remote control is high quality processed. (Sorry, but better than DAC 10) Most CDs have 10 or more tracks. So no problem, to accept the short wait until the desired title is selected. And the listener can once again listen to every single song. Often one concentrates too much on the favorite music. But that changes with the CDT 8. My motto: Since Nuprime CDT8, DAC 10 H and ST 10 my old CD collection became my new CD collection  :thumb:

Another question: is the cdp9 = cdt8 + 9028 based dac? Is the dac section better than the dac10?
Title: Re: CDT 8 Pro transport
Post by: rustydoglim on 15 Jul 2018, 02:29 pm
No. As we stated in a FAQ, a good DAC nowadays is way more than the DAC chip. The difference between ESS 9018, 9028 and 9038 are very small, and if you are not use to the chip, you could ended up making it sounds worst.  For example, someone who has implemented 9018 many times can make it sound better than someone who just use 9028.  Even if you are not technical, just take a look at the inside of a high end DAC. Try to locate the DAC chip :). Now think the rest of the parts and design doesn’t matter?
DAC-10H is still a better DAC than CDP-9 in some areas but they are very close.

If you are a headphone and speaker user, definitely go with DAC-10H - the tight integration of headphone amp and DAC makes DAC-10H unmatched by other DAC and headphone amp combo.
If headphone is not important, then CDP-9 is good choice over DAC-10, only if you don’t need the analog input.

would the CDT 8 be significantly superior as a cd transport to an oppo digital player?

Rustydog
Which digital output is best to use on the CD8T Pro?
Also, what DACs accept the HDMI I2S output?  Does the PS Audio DirectStream Dac?
Title: Re: CDT 8 Pro transport
Post by: rustydoglim on 20 Jul 2018, 01:28 pm
I2S can be used with other DAC but it was designed for future NuPrime products.  I heard that the I2S CDT-8Pro can be used with PS Audio.  It is best that you use the HDMI cable bundled with CDT-8 Pro to avoid using inferior HDMI cable.
Normally coaxial (other than I2S) should be the one to use.

does the CDT 8 play blue ray audio discs?
Title: Re: CDT 8 Pro transport

No SACD or DVD.  Just CD.
Title: Re: CDT 8 Pro transport
Post by: JackD on 6 Aug 2018, 01:26 pm
The CDT-8 Pro does in fact work with the Directstream Dac using I2S.  I have been using it that way for the better part of a week.  Haven't tried the other outputs yet and may not for a while.

Rusty, or anyone - I see that the Wyred 4 Sound Dacs have i2s input too.
Does  CDT-8 Pro work with Wyred i2s?
Thanks

If EJ is using the same pin out as PSA it will work.  Here is pinout diagram that they have published.

http://nuprimeaudio.com/product/cdt-8-pro/?v=7516fd43adaa  bottom of the page looks at a glance as if it will. Best bet is to send EJ the link to the Nuprime pinout and get his opinion.

It is killer!  Upsampling is neat. Contact John Casler, a great guy.

OK, that was the gentle push I needed. I sent him an inquiry. I ave been doing computer audio for the last 15 years , but it would be nice to have a  CD spinner again. Old habits die hard! I can't even quit spinning vinyl!

Wow on all levels! My CDT8 showed up yesterday. Packed perfectly. It sounded great from the beginning. No glitches. Done, now we have a spinner just in case someone wants to hear a cd they brought over. BUT NOT THE END OF THE STORY. A day later it's sounding fantastic! I wasn't expecting anything near this. The different sampling rates do sound different and are just plain fun.  All worth a try. 16-44 sounds superb and I don't even own an expensive digital cable.  I thought I was buying this for convenience, but it's Audiphile great! I have had so many expensive transports that didn't even come close to this. And John Casler's service is first rate. Now where did I put those feet and fuses? CD spinning is fun again!

Post by: AndrewA on 1 Dec 2018, 01:32 pm
Has anyone hooked one of these up to a Schiit Gungnir?

If so, can you tell us if the Gungnir clicks when Pause is selected?

From what I understand, different transports handle the Pause command in two different ways; one way makes the Gungnir click frenetically, the other way it's silent.
Title: Re: CDT 8 Pro transport
Post by: Samoyed on 1 Dec 2018, 03:17 pm
Never tried, and no clicks with my DAC 10.

 Now that I'm enjoying this way too much, I guess it's time to look for a new digital cable. Past transports I have owned favor either as/ebu or rca. It can be either, but usually one output is better Any ideas on which I should look for? Thanks in advance.

Don’t shoot me. I’m using a $20 blue jeans cable I got on Amazon. Lovely.

I prefer AES/EBU.  I am not sure it is "better" than SPDIF RCA, but the presentation is different.

You might also check with Jason to see if he feels one out is preferable to another.  You could also do the same for the DAC .

If you are still in a quandary, you might get (borrow?) an inexpensive AES cable comparable to your SPDIF RCA, and see which presentation you prefer.  Once you establish this, you can look for a better cable.
Title: Re: CDT 8 Pro transport
Post by: Eisener Bart on 29 Dec 2018, 03:49 pm
1. AES/EBU
2. BNC
3. SPDIF (coaxial)
4. Toslink (optical).

but I2S is on the top of list.  :green:
