Best Sonos ZP-80 Mod?

Have a look at the Pacecar mod via Empirical Audio. I've got one. Highly recommended.

How does the Cullen mod compare to the Empiracal?

Anyone?

Cullen mod - might be it for me, I am all ears.

Mrjstark, do you actually have the Cullen mod? If so, can you please elaborate? BTW, do any of these mods affect the Sonos' sw upgradability? Sonos typically comes out with a sw release once a quarter.

When will someone mod a Sonos (or other device) with an asynchronous capable USB out? Wouldn't that eliminate entirely the need for expensive clock mods on the transport box if you just turned it into a digital file 'pass through' and let the DAC clock do the heavy lifting? It just seems ridiculous to me that there isn't an easier way to transfer the file into the DAC cleanly without worries of transport jitter.

What am I missing here? Would love for one of the techies to enlighten me on this.
