Sonos Products

I've had a Sonos system for around 4 years. I have a ZP-100 and several ZP-80's (generation before ZP-90.)

My experience has been that the system is great for general listening/background music. Even with mods, it does not compete in sound quality with a good high-end cdp.

Depending on your reference, your mileage may vary.

I agree with the above poster. I have a couple of their products including the ZP90.
Great to listen for a party or just pulling ups some tunes to listen to.

It does not compete with my main system. I actually mainly use it on my back porch with an old Tandberg receiver I recently picked up. I actually like the different radio applications on the Sonos. Found some cool stations from Europe. The sonos systems make listening fun.
I do not use it for critical listening. I do think it sounds fine for what I use it for. Keeps me from lugging cd's around.

Remember if you want to go "wireless", one piece needs to be hardwired to your computer first.

I use Sonos in my computer based system, including the handheld Sonos controller. I am very happy with it.

But, as the other posters mentioned, there are issues with sound quality of Sonos. To begin with, I would avoid using the dac in the unit, and instead use the digital out and an external, higher quality, dac. However, the Sonos digital out suffers from a high level of jitter, which itself needs to be addressed if you want high end sound quality from the unit. Jitter can be addressed with either (1) internal modifications to the Sonos; (2) a downstream dac that is relatively immune to jitter; or (3) an external reclocker after the Sonos but before the dac. I chose to use a reclocker, which allows you to get very high level performance out of a computer based setup, but this approach is rather expensive.

Good luck.
