Comparing digital out the Sonos is supposed to have higher jitter than the Squeezebox, particularly the Touch, but surely use of a DAC that reclocks should negate this advantage.

In practice I have found that there is no discernible difference in sound quality between running digital out from the Sonos, Squeezbox3, G07, or Marantz SA11/2 into the DAC in either a G68 or a Benchmark DAC. The rest of the system at the time included Martin Logan electrostatics with BAT amplification. At the relative prices I thought there should be, indeed hoped there would be, but disregarding expectation bias the results were the same. I am not saying that they are necessarily "actually" the same but any differences aren't noticeable to me when listening for them and certainly not when listening to music. Using the analogue out, however, there was a clear difference in quality with the Sonos being the worst and the Marantz (depending on which filter was selected) the best, although between the G07 and Marantz it came down to preference rather than being necessarily better.

Having got that our of the way I then made my choice from which is the easiest to use for a predominantly classical music collection. The Sonos when controlled by an iPad comes out the winner as I can browse by Composer tag without having to install add-ons or swap Artist and Composer tags.

The big problem with a classical collection is the need to correct the tags when ripping. They are invariably inconsistent even when accessing a number of online databases with dBpoweramp for example. This may be less of a problem in a system where you find you music by typing in a search but is a problem in a system which also allows you to browse by Artist, Album, Composer or Genre etc.

The Sonos doesn't do 24/96 out, although as the majority of my collection is on CD this doesn't really matter to me although it may be important to someone else.
