Sonos DAC

Sonos does not support the USB output, I think. Digital coax or optical are the only choices. I prefer the digital coax.

You'd still want a good external dac whether you mod the zp80 or not. I have a Bel Canto Dac 1 that sounds great and are a great value now. If you can afford a better Bel Canto, go for it, it's hard to go wrong with them.

I've owned the bel canto dac 2 in the past and loved the sound. However, I had difficulties with signal drop out which was frustrating. I may consider another unit now though.

I agree with some of other posts. I personally think upgrading the power supply and possibly the output stage will give you more bang for your buck. I even want to go so far as to modify the male power input on the back to a more standard 15amp IEC so I can get a good aftermarket power cord. I use my ZP-80 with an external DAC and it sounds much better than the stock DAC in the Sonos. The Sonos can have too much sloppy bass as well as a harshness. The instruments are not very well articulated either. With my Esoteric D5 DAC, separation is much better.

What digital cable are you using?, I’m kind of disappointed by the improvement I get when I connect my ZP-80 to an external DAC. I have used the DAC section of my moded Opus 21 and the top of the line Integra receiver (in my HT room), with relatively minor improvements. I wonder if the AQ VDM-3 (RCA to RCA) cable I’m using is not a good fit.

Anyone else has experience with different digital cables?
