Grace 901 replacement: Grace m902

post #1 of 209
Thread Starter 
It appears Grace Design is planning to launch the replacement of its 901 headphone amplifier, the m902, and it seems quite promising...
It should include:
-Balanced and unbalanced analog inputs
-AES3, S/PDIF, TOSLINK and USB digital inputs
-Variable level unbalanced analog outputs
-"Latest generation" 24/192 DAC with s-Locktm dual stage PLL
-Precision level control with a 95dB range in .5 dB steps
-Crossfeed circuitry
-Infrared remote control (Optional)
-No electrolytic capacitors in the signal path

Grace Design has some preliminary info about it in pdf at:

Wow USB inputs, analog outputs, crossfeed, remote control, looks like a great new product Hopefully their DACs will catch up with their headamp section for this new version.

Oh boy. Obviously, we'll have to wait until it's actually released and some people get to hear this thing. But on the specs and features announced so far, it looks terribly terrriby enticing. And if it debuts for the same price as the 901, then I may have to be an early adopter.

The 901's DAC was mediocre at best. If they are able to catch up to the DAC1, and have analogue outputs, well, I think they would have a very nice product on thier hands.

This Grace seems to belong to a new component category: the headphone "receiver". For sure will be the most feature-loaded headphone amp it seems. Wonder if so many features together might compromise performance in some of those features.

Also, no electrolytic capacitors in the signal path... erghhh... It is my understanding that no caps film or otherwise should be in the signal path. Senior electronics gurus please correct me if I am mistaken.

Thoughts...

This product would be perfect if the internal DAC and headmp are awesome and there's a stepped attenuator inside. Still the lack of a balanced output reduces the unit's effectiveness as a DAC for my purposes.

Hmmm. I have been interested in a source upgrade. Uh, I guess this is more than a source.......

I believe samgoody was selling one a few months back. I guess you missed out!

No SNR, THD+N, or dynamic range numbers, so we're left guessing as to what "latest 24/192 DAC" actually means. Sombody will have to get this and take the top off.
post #11 of 209
That looks really sweet. Any rumors as to when it will actually be out?

It seems the stepped attenuator of the 901 has been replaced by a rotary encoder. I'm not sure what the latter is though. Almost seems like digital volume control.

A little bird at Headroom told me that they will be getting them sometime in December.

Happy Holidays to me!

Samgoody always sells the good fantasy stuff.

Seriously?!?! Well this will be fun indeed. I love that it has a USB input option built right in, though like Neil said, too bad no balanced outputs for a total solution, but then again it is supposed to be "just" a headphone amp. I guess with this you could ditch you remaining RME, eh Ed?
