Another new DAC: Audio Mirror


Just ran across this last night. Never heard of them before but
as a Minnesota company tweaked my curiosity.
Audio Mirror Tubadour III non-oversampling tube DAC. Sounds interesting.
If anyone runs across one and has a listen please post.

XLR analog outputs are available as an option which I realize does not make it "balanced".
"Could be" what many do these days, on the output of sources and the input of amps, they just add a single ended to balanced output or input opamp converter, which sounds worse than the (single ended) rca which doesn’t use the opamp.

And the only way to find out is to look at the circuit diagram or visually trace the circuit to see if it’s a pseudo balance or a real balanced circuit from input to output, you’ll be surprised how many are pseudo, especially tube amps, pre’s and sources and R2R dacs, even some solid state pre’s and amps though not as many.

Good to see he's a stayer in this industry Anthony, seeing you've had dealings with him before, any chance of finding out what d/a converter he uses?

Hi Vlad.
We’re interested here and more so on SNA where I posted your new dac, what is the Analog Devices d/a chip your using, on SNA it’s bandied about that it’s the 20bit AD-5791 is this correct ???

 For balanced outputs I use balance output transformers if you are curious how it’s done.
Thank you for your interest in the new DAC,
So, single ended from the digital to analogue conversion output, then converted to balanced at the end like some do with an opamp, but you’ve use a transformer instead, as I’ve seen others do also.

Cheers George
