Has anyone tried this amp with 600 ohm Beyers?
Mine should be with me veeery soon, happy me.
The only gripe I would have with it is that it does not accept an external power source.
Can it be powered from USB when not used in DAC mode?
The D6 can, indeed, be powered by the USB cable when using the Aux input. It also comes with a 12.6 AC adapter that you can use for desktop power if USB is not available as well as for charging. This is so stated in the User manual.
Quite a versatile instrument.
I hope that will be true. The manual says:
-Powered by 12.6V Li-polymer rechargeable battery pack,
or USB power
But since I cannot test I will hope you are right as that would be what I want - if it is not, I will ive with it.
HiFlight is correct (and is very knowledgeable about this product, by the way). You can power the D6 via USB while listening through the AUX port -- I'm doing it right now just to make sure. And of course, can be powered via the 12.6v adapter/battery.
I agree that the AD797B's have a very full, rich sound with nice tight bass. It also has an amazing soundstage, wide, deep, intimate... as necessary.
But! you have to @least use dummy buffers... or the great soundstage will be very wierdly narrowed/congested by the stock buffers.
My latest combo is 797BR's for buffs and 797B's for Center, the sound is seriously to-die-for. Richer more impactful sound than with dummy buffers.
Quite possibly better than the impressive OPA627AU in L/R w/Stock buffers combo, I don't know... I haven't had the urge to roll-back to that combo yet.
@Palpatine:
I felt that my DT990/600's were driven quite Well with the D6, and sounded great with the AD797B's. If this means anything, I prefered my D6 to a Millet Hybrid MiniMax for driving my Beyers.
Sadly they're down for a driver replacement, I'll re-cable them too.. so, I won't be able to test with them for awhile.
(heheh yeah, it's not readily apparent, but all three 797B modules are of 2 to 1 adapters)
Agreed HiFlight, with some high-end op-amps... USB power alone is not sufficient. For that caveat, It's a very small price to pay for the "Scrumptious" SQ bestowed upon said device.
(If travelling, 11.6v? battery power should be quite sufficient until re-charging is necessary)
I also use a Gamma1 DAC that can be run off USB power, but I choose to use a dedicated wallwart with that too. The PC/USB is crappy/dirty/contentious place for 5v power and Audio signals.
For power, use "dedicated" when possible, especially with your @HOME setup. There then should be no reason to "need" the convenience of USB power alone.
Some things to think about if you're in the "i only uses teh USB juice" crowd.
