There are implementations where each dac chip or channel is run off its own transformer like with this Audio GD unit shown below.There are a lot of higher end DACs that use separate DAC chips for each channel. I was wondering if this forum had any opinions as to the benefits (or potential issues) with that setup over a single chip operating on both channels?

Yea that's the kind of thing I'm talking about. Assuming it's implemented correctly, what are the advantages to doing it? I'm guessing if it's not implemented correctly there could be all kinds of phase issues too right?
I hope to buy an Audio GD HE-1 someday.And we know those guys are masters of quality implementations....

Yeah I've read one of them. II didn't see the second device review though. I'm still interested in them.Have you read the Audio GD test results here?
You might want to think twice about that....
Same with RME ADI-2 Dac with its AKM 4490Khadas tone board is an implementation of ES9038Q2M in stereo mode yet it's performance is at least on par or better than a dual mono config like the Topping D50.
FWIW, I've heard the HE-1 (with MUSES8920 opamps as DC servo) in a local store here, it's extremely clean sounding unlike most Audio-gd amps which have some color to them. I would be very surprised if the HE-1 doesn't measure well but you never know.Yeah I've read one of them. II didn't see the second device review though. I'm still interested in them.

I think it also appeals to consumers, 'dual chip' waowww
Nice! So what do you mean by "with muse8920 opamps as dc servo)?FWIW, I've heard the HE-1 (with MUSES8920 opamps as DC servo) in a local store here, it's extremely clean sounding unlike most Audio-gd amps which have some color to them.

I guess they simply do not believe it's any better to use two?Yep. Even though that extra chip is like the price of a McDonald's Happy Meal.
AFAIK stock HE-1 comes with OPA2134 opamps, it's just that the HE-1 I was listening to had MUSES8920s in it. I don't know what difference the opamp swap makes though.Nice! So what do you mean by "with muse8920 opamps as dc servo)?
