NuPrime Reference Evolution - a breakthrough product with 1M Ohm input impedance

Might we be looking at a new preamp possibly to compliment this series?  Life is too short not to have a great preamp.

I know.  There are some alleged great preamps out there.  But, NuPrime's purpose keeps my radar bleeping.

Would love to see a comparison between the REF EVO and MolaMola Kaluga.

Please do not compare Ref Evolution with Hypex NC500 etc.  That's the job of STA-9, STA-6. Or ST-10.
Come on guys, we designed this amp to compete with the best amps in the world, at any freaking price. Bring it on :).

Sorry I went overboard a bit. I have a simple explanation why NuPrime is able to innovate while Hypex and other volume production amp companies don't do (I didn't say they can't)

NuPrime designs amps for its own consumption. Our chief engineer is free to innovate and if the new design costs more, then it goes into a newer model at higher price.
On the other hand, a volume production amp company has to keep its cost low (most of these amp modules are sold way below the retail parts price that you can buy online, at 1000 or 5000 units quantity, it is really really low :)). Sure they can innovate, but that's not their business model. They use large OEM factories to make these boards at low cost, and you just can't make 100 to 200 pieces at a time.

It is like buying a burger from McDonald, even if it is their top of the line Angus beef burger, it is still mass produced, not the same as what you can get from a fine restaurant.

Or even better comparing the REF EVO with some of the top cost no object amps i.e. Accuphase, Audionet, Constellation, Soulution, etc. since that's their stated target. Guess we've got to wait until they're actually released before any such comparisons can be made!

Hi Jason,

Would you recommend to combine the Reference Evolution together with the MCH-K38?
- Front Left / Right connected to the Reference Evolution
- Center and Surround connected to the MCH-K38

So for stereo music, I could just use the Reference Evolution and for multichannel (movies) I could add the MCH-K38?
Does this make sense?

Any news on when we are likelto see the Evo ones, I understand there has been a further delay till the end of May?


It should be on schedule this time. The delay is caused by the supply chain - CNC and SMT vendors all have backlog, probably some manufacturers moving production from China back to Taiwan due to concern about trade "war" between US and China.  I think those companies probably plan to move anyway, China is no longer the lowest cost manufacturing place where it used to be, a lot of companies are already moving production elsewhere.

Thank you Jason,

I have placed my order with John at TotallyWired here in NZ and am patiently awaiting their arrival. Poor John has probably had enough of me pestering him as to their release but he has been extremely good to deal with and very excited to hear them also, I gather.

Regards Steve


There is a pair sent to Germany for next week's High End Show in Munich, and I will take some internal photos.

the EVO1 has not been seen at Monaco......why ?


Didn't display because there is no live demo this year. The amps were picked up by one of the distributor.
Photographer took internal photos yesterday and Evo One product page will be up on the website this weekend.

I'm waiting for the trickle-down technology into an IDA-16 type integrated. 


Evolution One product page is live on the website.

There are more photos to be added tomorrow.
Quite a few design innovations here.  I noticed the capacitor array have a new pattern.
