Best Sonos ZP-80 Mod?


Anyone with first hand experience with a modded Sonos?

I've seen a few ads, though would like to know whose leading the pack.

My ripping is Lossless and I am currently running my ZP-80 through a Meitner BIDAT

Thanks

Steve,

How would the Pacecar compare in SQ to a Prepro that has built in streaming, like the Denon Prepro. In this case the flac files are streamed from a NAS drive directly to the Prepro. Shouldn't this have the best SQ?

I have a Sonos, and the convienience is much better than the Denon interface, so the Sonos may still be the way for me to go. But, I am curious about the SQ trade-off.

Thanks,
Darrell
I have Cullen modified ZP-80 feeding an Accustic Arts DAC MKII into a Cary SLP05 (Tube)preamp into a Bryston 14BSST (600 watts). My speakers are Aerial 10T. All cabling is Acoustic Zen. In an A/B test of modified and un-modified, my wife, a friend and I all felt that the difference is immediate and dramatic. Mod has more transparent sound, no grain and tighter bass. Cannot compare to other mods because have only heard Cullen. However, in my system, well worth the money.
For about a month already i am enjoying Sonos with Pace-Car. My device has Ultraclock inside and WBT Nextgen as SPDIF output connected through Stereovox XV2 to Chord DAC64. I must say what Pace-Car does to my system is magic.
Chord has RAM buffer with 3 settings: off, medium and large. Common rule is to use medium or large buffer, then DAC averages digital sources to some level. Even pretty expensive Chord Blu transport is usually used with medium or large buffer.
But with Pace-Car best setting by far is BUFFER OFF. Music is smooth, focused and alive. I used to think that my system produces very fine soundstage - wide and deep, good separation of instruments. Now everything is much more real, microdynamics is better.
