Hello !

I just bought an Amg Sta and an Alita. Superb combo with my Harbeth M30.1. :)
But... do I have to wait for the new Amg Dac with the Amg Sta, what would be the differences please ?
I prefer AKM sound than ESS for exemple.

Thanks for answer, best regards from France :)

We will have opportunity to compare when AMG DAC shipped in April (this time for real, after months of chips delay  :duh:)
When we start to write the manual (next week perhaps), then we will have more info.

What happened to the AMG DAC? Was he late again?

Delayed again to sometime in May.  It has been in queue for SMD assemble, this is the part that we don't control.
In manufacturing electronics, there are many suppliers in the pipeline: aluminum chassis, aluminum anodisation, parts purchases, bare PCB, SMD assembly, board assembly, final assembly and test.  Our factory only controls the purchases and last two steps.
Once we completed SMD assembly, it will be full speed (about 2 weeks for board, final assembly and test).

Confirmed that the final assembly will start this week at our factory where we have control over the progress. We are definitely going to ship during the last week of May.  :thumb:

Jason,

Please share any details about this new DAC. How is it voiced - warm, neutral, analytical, etc? With or without volume control?

How does it compare to the Evo DAC?

If paired to the Evolution One dual-mono amp, how would it sound?

There is little room for improvement to state of the art DAC chips, so what makes AMG DAC different is the extensive use of Class-A transistors to give it an analog sound.

Jason,

Thank you. Of the two DACs, which is more analog sounding?


Which one is right for me? [I know. There's only one way to learn this.]  :thumb:

Jason: Can you explain to us if this DAC reads the MQA format?

The specifications do not say anything about it, but it is very surprising that a DAC of that price value does not say anything about it, since the DAC-9X, which is much cheaper, does read that format.

AMG DAC does not support MQA as it required XMOS USB chip.
We want AMG DAC to have high-end analogue sound so that takes precedent over MQA.
The plan is that MQA, if needed, will be supported across all our streaming devices so users can use the future AMG Stream to decode MQA.

Since the new AMG DAC is designed as a "reference-class DAC" with a high end analogue sound, wondering how its sound quality compares with the EVO DAC or other NuPrime DACs. Is it the new reference? TIA

Good question, I have to check with chief engineer.  I can guess that they are the same level, just sounded different. Evo DAC is known for super detailed and neutral.  The AMG series usually have the warmer, fuller sound.

The design goal for Evolution and AMG series are slightly different.  We consider both series our "flagship" series, whereas the "9" series is the giant killer.

Therefore, Evolution DAC was designed to be exceptionally detailed and neutral. AMG DAC is still incredibly detailed but adhere to the AMG series sound characteristic (fuller/warmer, analog). This is the result of design and component choice (not inferior parts but parts that tend to have the desire sound characteristic). Evolution DAC cost more because to achieve its design goal, the power supply and noise isolation would have to be superb. Furthermore, Evo series come with expensive chassis and connectors.

Jason,

Thank you for the clarification. I have another question.

I am a very happy owner of an EVO STA. It's both warm and revealing - just marvelous sounding in my main system. Could the AMG DAC + EVO STA combination be too warm? Has your engineer listened to this combination?

Thank you.

Michael,
As I have not heard the new amg dac, I cannot exactly answer your question.
However, I can tell about experiences with my setup.
A year ago I bought amg pra and amg sta, and later evo dac and stream-9.
It played very well, but as I had read many reviews of the evo one, I decided to try them out.
At the same time, the new evo sta came out, so I borrowed one as well, and was able to compare the 3 amplifiers.
Conclusion of the test ended in favor of the evo sta.

And I find it works really well with  the evo dac, neutral, and very realistic way to play music, for the first time ever, I felt that digital music sounded right and real. As I have a lot of lp’s, I needed to keep the amg pra.
But as the digital music now sounds so good, and streaming with qobuz offers that much music, it is not often the grammophone is used.

Good luck with your decisions.
Lars

Lars,

Valuable input! Thank you:thumb:

I've been bouncing around trying to decide between three DACs for a while now- the AMG DAC (because it's so new), the EVO DAC, and another brand's DAC. I think it's time for me to stop worrying about details, and take the plunge.

Fortunately for me, I own precious few albums (35, I think), so I'm not overly concerned about being able to connect a TT to this system.

Time to send John Casler another email. Oh, John.... :icon_lol:
