Another new DAC: Audio Mirror

Thanks  vassils...will do....any other upgrades/besides the Caps and power supply

If you really want to tweak it to the max, I would change all signal path resistors to Vishay Z-Foil. 
And going into the world of diminishing returns, controversial topics, and things that may not be audible in every system, but I did on my ANK DAC... I would replace the IEC inlet, RCA connectors, and the stock fuse. 
I think the Audio Mirror DAC had one of those combined IEC / fuse inlets.  Furutech FI-03 (R) would be a good replacement. The SR Blue fuse worked well in my system.
I would put ETI Silver Phono Pods or WBT-0210 Ag NextGen RCAs. WBT are cheaper from European distributors. 

Also, I read you got an XLR output. Is that what you use? If you have unbalanced inputs on your line stage, try them out.  

Mucho thanks Vassils on the other upgrades....but a little confused on why go unbalanced?..Have Acoustic Zen Matrix Reference II balanced and can switch to sum AZ Silver Reference II single ended..........Also Peace and much Love & Prayers to All Of New Zealand’s Sister’s & Brother’s and beyond(were all CREATED in the Image of THE SAME GOD!! Amen!....................One thing I forgot to mention is that I am running all inputs into A BAT tubed pre ...and running Balanced makes a HUGE difference....

If I understand audiomirror's post above correctly the balanced output passes through a transformer (same with my ANK DAC by the way). I am a minimalist and would prefer less components in my signal path. But this would be gear/system dependent. You should try both if you can and decide what you like. 

My ANK DAC sounds a little better with RCA interconnects, but that might be because my line stage is not fully balanced. I have a balanced input, which passes through a transformer inside the line stage. So what I might be hearing is the side effect of the transformer in my line stage.

In any case, I thought I would suggest to try the RCA output as well. If you prefer the balanced output, obviously there is no point to replace the stock RCAs. 

Much Thanks Vassils for all your input...and will try both and report back after i receive my AM Tube3  Dac back from the Bulgarian who goes by the  Alias Vlad....HA!!

You are welcome. Keep us posted. I am very curious of the result. As I mentioned above I am considering replacing the ANK DAC with an Audio Mirror DAC (and Duelund caps) and getting an Innuos Zennith MK3 music server. 

Also, I forgot to mention in my previous post, but one of my previous DAC's (Ayre Acoustics) sounded better with the balanced output even through the transformer on my line stage. That was a fully differential design, though. Those tube / Analog Devices DACs like the ANK and AM sound better single ended in my system.
