We are glad to have so many satisfied customers. The past two years have been a great leap for NuPrime.
We have several ideas to put into the "next gen" amp. But I will like to hear what you have in mind.
I want your wish list, if anything is possible.
-
1. MCH K38 as a 2-channel reference amp or as mono amps.
2. Redo the ST-10 as mono amps with upgraded caps
3. Upgraded IDA-8 with 150w/ch
~~~~~~~~~~
4. DAC-10H with the 9038 chip
That's a good start, I guess.
Thanks for asking. :)

Jason,
What a great question. I'm five days in with my IDA-16. It will have 70+ hours in it this evening so I'm getting a feel for it.
Nuprime is on a great course. I would like to see NuPrime continue to produce category leading DAC/integrateds for all budgets.
I believe there is a very good chance that my IDA-16 is an end point for me; it is that good. :thumb: However I wouldn't mind seeing a NuPrime Reference IDA-16.
As Michael mentioned a two-channel Reference amp would be great as well as a reference two channel pre-amp. I believe a reference two-channel pre/amp combination would get lots of attention and would compliment the Ref 20 monos nicely.
Cheers,
Scott

- option for rack mounting somehow (if not directly in the chassis, maybe rack ears? maybe in a side-by-side config if doing monoblocks in the smaller chassis?)
- selectable high pass filter for those of us who want to integrate a sub (and if there were subwoofer outputs, perhaps a matching low pass filter as well)
- Dante or AVB some other ethernet interface (unlikely I realize)
- two sets of binding posts selectable as speaker A or B like the old school receivers; also have it remember separate volume settings on each output (this would be perfect for those of us who like to have several speakers hooked up and/or for comparisons)

An hybrid amp w/remote volume control to drive fullrange drivers direct from the CD Player with 6SN7/6SL7 input tube around 50Wpc with wide bandwith, if monoblocks better.
-
I'm with Michael regarding a MK-38 (MK-32)? that is 2 channel or mono blocks, this would cost less but still have the sound quality that people seem to really like.
It also seems right up your ally to do something like Sonos does with wireless connectivity and amps at different locations running off of the main system. Purpose made for this application, maybe using your new entry level amps as the satellites.

25 watts would be enough for me.

My Zellatons are 86 db but I do not listen loud. I want to try those new Omega 3HO's which are 98db?
-
1) A higher powered amp for power hungry speakers.
2) a digital direct amp fed by a digital signal (along the lines of what TacT and NAD have offered).
3) both of the above on one package.

Just my 38 watts/channel Decware Zen Mystery amplifier. That will do me for good!

I surprised, its some unsual. I wonder if these post Transistor era amps have strong bass in the small versions as 30-50W?

Devialet makes exactly what you are asking for:

Hey Rusty, whatever amp you build is great, just don't ship it with a $2 power cord would be my wish. Get a GREAT cord!! Plenty of excellent vendors here on Audiocircle to partner with, why not throw in some isolation devices too.

The problem as I see it is waste, so much of that :high power" that isn;t being used is wasted as heat. Why not just get active speakers with amps customized for the drivers built in? Less expensive too.

I like my inefficient speakers (SP Tech Revelations) and power isn't as pricey as it once was. Don't particularly care if it is wasted as heat as long as the speaker's sonics aren't negatively impacted.

I don't know if you were even considering any hybrid amps, but as they've already been mentioned, what would be nice to see in the marketplace was one with utmost flexibility as to what tubes could be used. Just as the Primaluna's accept everything from EL34s to KT150s, and can be used in both triode and ultralinear mode--having those options in a hybrid design, using the minimum number of tubes (single-ended?), capable of driving low/varied impedance speakers (a full 50-100 watts from 4-16 ohms) would be a must audition! I'm imaging an OTL-like sound that could be enjoyed without compatibility worries. A bridgeable/mono design much preferred--in fact I just ordered a STA9 as an interim (possibly upgrade?) amp in part due to that very flexibility.
P.S. I suppose I should also mention that in a discussion on Agon, folks are wishing for even higher switching frequencies. (I don't really understand the technology. myself)
-
IDA-10.
(ST-10 power amp stage combined with dual AKM AK4497 DAC and XMOS U208 USB chip.)
-
After finally giving your ST-9 as a mono block pair a go with my Rogue 99 super magnum; i must say i am so impressed. I fully intend to upgrade to the Sta-10... (but am i really upgrading??.. after going through your circle, it seems that with st-9's as mono blocks, there isn't much difference versus the Sta-10 ) . My wish would be for you to offer a bridge amplifier between the Sta 10 and the reference 20's. . in other words, you have this huge gap in your line between $1600(Sta 10) and the reference 20's at $8000 a pair. Unless I've missed something, I believe it would be advantageous for you guys at Nu prime to offer something in the $3000- $5000 range. in all honesty after my experience thus far with the St -9's ..., i would purchase tomorrow
i would have never believed it... great work and engineering !!!!!

Someone said Devialet so I feel compelled to mention Lyngdorf, which also makes the above (descendant of TacT tech, I think).

Some seem to have missed the point of the thread. The OP is the Nuprime CEO. He is asking what future products we would like to see from Nuprime. He doesn't want or need us to post links to competitors. This thread is in the Nuprime circle.
Think about it. :duh:
-
No limit?
Hmm... ok.
I haven't followed the trend, but I'd love an amp with a wireless send to the speakers. I'm fed up dealing with "spaghetti" behind my amp. All those wires add up quickly, and it becomes a real mess fast. Is there a system that has hifi wireless send for amps?
Also, if it's a 2-channel amp, 2 pairs of outputs, each with selectable high and low pass. It would make it a breeze to merge low end woofers (or subs) and a fullrange, or any 2-way combination.
-
So can NuPrime implement the parallel CLass A and Class D that Devialet does? I do not know the intricacies but I see NuPrime has a separate, if you will, Class A and Class D circuits in series. I believe the Devialet has the A and D circuits running at the same time.
From what I have read if NuPrime could do that for thousands less than the competition they would be onto something. And I would be interested in trying it out against my Wells.
-
Lower prices (without loss of quality) of course.
Smaller, with upgradability.
A website that doesn't keep going to blank pages.
-
Websites modeled to cel phones are PITA.
-
1) Pure monoblocks in price range 4 000 USD.
2) Pre-Amp with 2 pairs of XLR output which can control 4 channel simultaneously.
-
It's all about the sound, a reference one, in a simple stereo box.
If you can get close to the sound and musicality of the Reimyo KAP-777, at the fraction of the price.

I want a 6-7 channel box with up to 100W/channel that runs cool, weighs about 20lbs with XLR and trigger inputs.
Or an amp that takes HDMI input in multi-channel PCM format and powers 7 speakers. Still cool running and 20lbs.
Or a wireless mono amp that doubles as a speaker plinth so that I can convert my passive speakers into actives.
-
I admire the Nuprime gear. For disclosure, I own a Lyngdorf TDAI 2170 and am very happy.
In looking for a replacement, it would need to be a quality, all digital integrated with digital and analog input (the latter via analog to digital conversion) 4 or 6 Chanel (100 WPC or more) with adjustable digital crossovers and automatic room correction via room perfect or similar DSP software. User friendly of course.
In a perfect world, it would run stored music from a hard drive and stream from Tidal etc. Did I mention firmware upgradable?
Well you asked.... :D

Say, artur9. Have you looked at the Nuprime MCH K38 amp? It mostly has the characteristics you mentioned but weighs about 30 pounds. It also sounds amazing (I have heard it.).
-
Is there a system that has hifi wireless send for amps?
Um... are you thinking of wireless speakers that have built-in amps? Basically all you need for that is a wireless transmitter, a receiver, and a plate amp.
Or are you thinking of wirelessly sending actual electrical power to a specific paired device over moderate distance? Because this doesn't exist, and if NuPrime ever figures out that technology they would revolutionize the tech industry and leave hifi in the dust.
-
Integrated with RIAA.
-
Wireless signal input, customized to the individual driver load, and built into (active) speakers.
-
Having just recieved & hooked up my STA9, I'd like to add that a little more space between binding posts, rcas, etc. would have been appreciated. (Only really an issue because I kept trying to connect it without moving my a/v rack).
-
an amp designed for high efficiency speakers?
my dda100 doesn't sound that great with my altec speakers but great with other more traditional speakers.
i suspect other digital amps do not sound so great with high efficiency speakers.
-
How about a modern version of the Quad 34 preamp, but as an integrated? Bass lift and tilt controls!!!! Then make the amp section customizable so that you only buy the amount of power you need. I think that would be awesome.

Wow, a lot of wishes. This is great. As someone has nicely pointed out, this is a Nuprime circle and topic is asking for future product wish list.
Please avoid promoting other brand's products here. Thanks.

A 250 wpc amp at 8 ohms that doubles at 4 ohms, is 2 ohm capable and leans just a bit on the warmer side, with detail, air and transparency and does not weigh 100lbs like my current amp. High current. True balanced with XLR and single ended inputs. It must not accentuate sibilants and it must play well with tube preamps. Oh yeah, it must be affordable. Is that asking for too much :)

In this line an IDA-8 with the power source of the KCH-38? That way we could see the doubling of wattage at 4 and 2 ohms, in a small portable box.

The current MCH-K38 amp modules can do that already. STA-9 with adjustment will also meet this requirement, or you might like it the way it is.
We are aiming to advance the state of the art much further beyond this.

I would like to see an integrated amp that has a feature where you can by pass the preamp section and use another preamp in addition to a preamp out. It should also be modular and have a built in DAC that can be upgraded as DAC technology improves.

I think there are processors that use cards you swap in and out as tech evolves, the problem is the cards are almost as expensive as just buying a new pre-amp.

While I appreciate the spirit of this thread and your post I think you are ruining your objective. You should welcome input about your competition, it reveals a lot that you may not be aware of. Plus it saves you a lot of time and expense doing market research. Here is a link FYI-

The new card should be affordable. And there is no reason for it not to be.
-
Schitt and Aqua both have had the ability to swap DAC boards for a while and doesn't cost more than a new unit or close.

Realise that Mr Lim is interested in a wish list for amp specs, but just wanted to put in a couple of suggestions on amps for HT use. I'd love to see a version of the STA-9 with trigger inputs just like the STA-6, for use in a home theatre system. Also, if there's a way to retrofit the sta-9 , sta-6 chassis (and upcoming RPi chassis) with rackmount ears / fittings to fit in a home theatre rack cabinet or pro audio rack case, it'll be great too!
Looking forward to news on the Omnia and the RPi chassis - it's great to see a company such as Nuprime leading the way with truly exciting audio developments!

Thanks but this is not a competitive market research that I am conducting. I specifically wants to know what our customers like to see in future Nuprime amplifier products. But I like your point and I might start a new topic asking for competitor's products.
-
Since I use subs, I wouldn't mind a built in adjustable high pass filter in the stereo amp so that could remove extra unneeded effort put upon the amp and the speakers. Perhaps it's not practical since I've never seen it on a stereo amp before but I would love that feature. Also, it should go without saying, the crossover should as transparent as possible
-
I want an integrated DAC-amp much like the IDA-8, but not hindered to better sell higher end products. I need two optical inputs and a USB B input. The coaxial is optional.
So, I have to buy into the twice as expensive IDA-16 just for that extra connector? It doesn't make sense.
Make each product really a better hardware than the smaller product, that will sell me on a twice as expensive product. Don't just limit the connectors so people need to upgrade. And don't push the space concerns issues, you can make a slightly bigger case and fit those extra connectors.
For instance, if analog connectors are digitized, avoid them and provide another real digital input.
Also, make te proprietary USB spdif connector a hybrid that can take iPhone and iPads connector to do a direct play of local music. That will make it much more versatile, again, instead of pushing your omnia as the only valid solution.
Peach tree has, according to reviews, achieved the best possible sound with that direct iPhone connector and locally stored high fi music.
As it is, that connector is a waste of space that, again, could fit a more versatile and universal connector.
The amp section should be 4ohm-16ohm compatible always.
Some minor tunning of bass, treble and balance could help cope with less than ideal components, but I understand the technical reasons not to include those, so maybe a 'switchable' module that can be bypassed altogether if not needed?
That would be my wishlist, best regards,
Rafa.

Amp where one could "dial-in" sonic preferences wirelessly would be nice! 8)
-
That's hardware EQ, that will required an integrated amp with DSP DAC. Some entry to mid level integrated amp (especially chip based amps) can do that, but it doesn't sound good for high end system.

We are glad to have so many satisfied customers. The past two years have been a great leap for NuPrime.
We have several ideas to put into the "next gen" amp. But I will like to hear what you have in mind.

super amp A (2ch): DAC ES9038PRO (with bluetooth and wifi) + (A) - Op Amp + Full Bridge (F) + Power supply can be Switching (S)
super amp B (8ch): DAC ES9038PRO (with bluetooth and wifi) + (B) - ULCAM (Ultra Linear Class A Module) + (C) - SECAM (Single Ended Class A Module) Full Bridge (F) + Power supply can be Switching (S)

I was thinking more in line of relay switch selecting between diferent hardware configurations or combination thereof.
-
We are thinking of offering custom opamp (build with transistors) for sound tuning in some future products.
-
An idea: work on an AI module able to detect our cognitive hearing abilities and affinities, delivering signal to the speakers accordingly :wink:

4. DAC-10H with the 9038 chip
That's a good start, I guess.
Thanks for asking. :)
its interesting to me to see people excited by ESS chips, I have been consistently underwhelmed by every design based on these chips. $500, $2k or 10k. The biggest waste of my time and money has been the Dual mono balanced femto clock LHLABS DAC based on ESS. but then again im always disappointed by every wilson audio speaker as well so what do i know? :D
-
...so what do i know? :D
Yes, but you haven't used their Lightspeed cables :icon_lol:
-
We are thinking of offering custom opamp (build with transistors) for sound tuning in some future products.
This could be interesting... I assume in these cases the opamps would be used as part of the gain stage or input buffer?
Audio-GD did similar things early on in their amp making days, with several different modules for flavour.
An idea: work on an AI module able to detect our cognitive hearing abilities and affinities, delivering signal to the speakers accordingly :wink:
Much easier to create a cerebral alteration fluid that can be self-administered orally until your cognitive abilities match your listening level :wink:
-
I'd love to see a sub-$1500 integrated amp/DAC, above the IDA-8 but below the IDA-16, that has at least two Toslink optical inputs while retaining at least one analog input. I would have bought a Nuprime product weeks ago, but the number of digital inputs are very limited on most of your products.
-
i am just waiting for something quite simple:
- ST-10 in mono-amp configuration, all the features of the ST-10, same sound plus a superb soundstage
- I do not think this is too difficult, and should not cost a fortune
- 200W x unit is enough for me (speaker 89dB)
-
When we are ready to introduce ST-11, it will be based on ST-10, but only in mono.
-
ST-11 mono-amps?
Great!
thanks.
I guess quite a lot of people will be interested....

Back in the good old days when Wind Chaser and myself owned John Iverson's Electro Research Ek-1 Strain Guage Cartidge systems, the first two in Canada; Wind had a dream of the ultimate power amplifier. He had a Sumo 9 running Acoustat II and I had either the Classe DR2 or Iverson's Electron Kinetics Eagle 7a on Acoustic IIIs, forget now which amp I had at the time.
Jon Iverson pulled up with a semi trailer to Wind's house and he had some folks bring in a monster amp and run massive, 1 foot diameter, power cables back to the semi. Then they powered up the nuclear power plant in the semi and while Wind was in his listening chair John Iverson looks and said to him, you want to hear what a real amplifier sounds like - well here you go, and he plugged in the monster cables to the amp. The music played and Wind's brain blew out of his head. Now THAT's an amplifier!

A design that offers the following.
Frequency response flat from 10HZ to 50KHZ
Proper tonality uncolored sound not bright,dark or thin
Able to reproduce harmonic overtones and decay
Minimal or zero distortion
Body and weight to music
Transparent yet not thin
Able to give emotional impact without fatigue
Reasonably priced
SS or tubes or hybrid no matter give me tonality

Good tube SE amps have nice even harmonics(2º, 4º).
-
How about an amp that covers the basic fundamentals like the ability to maintain linearity, accuracy (to the extent possible), speed/rhythmic drive, low noise, continuity and flow, dynamics of the micro as well as MACRO variety, high efficiency/reliability PLUS the ability to:
1) Scale between analytical to neutral to musical/tubish warmth on the fly per the listener's preference and/or source material dictates
2) Choose power level (wattage)
3) Modular and upgradable
4) On the external side: choose your own armor that better fits one's style (more choices beyond the typical color options) and preference. The better the build, the higher the cost, vice versa.
A more unique, customized solution instead of the typical cookie cutter approach. Is this possible? Oh, still be real world, reasonably priced.
-
This kind of preamp dont exist in western world, an Marantz and Matisse emulator for just 1 grand it would be my favor preamp:

Ideally I would like to see an integrated amp with a modular DAC or no DAC at all. As dac-technology moves forward you simple change the module. I also like my hifi to have good looks and good build quality. I think Nuprime looks OK but there is room for improvement.
-
A useful mod would be user-variable sensitivity in the power amp inputs.
I use a high-gain valve preamp (14db of gain) which often causes sensitivity problems. (Not with matching valve amps which often have input attenuation, but with solid state).
