How would you improve the sound of Squeezebox?

Cerrot,
Please comment on the addition of the Channel Islands Power Supply. I would be interested to know the difference over the stock switcher.

Get a better power supply. The wall wart that came with mine creates all sorts of noise in the AC. Almost any transformer based supply would be quieter.

Adding the CI gave it a blacker background, improved soundstage and detail but what really did it was the benchmark (after the power supply upgrade). I use a shunyata diamond back with the power supply and also upgraded the umbilical, which all added to the power supply's increased performance. The tinny sound went away, but it was still thin, though not as thin as the wall wart. The Benchmark really makes it a satisfying source. I didn't want to add the benchmark w/o first doing the power supply upgrade. My thoughts were to get the SB as close to a transporter as I could, so I thought the power supply and dac would do it. I haven't heard the transporter but as I am now tremendously happy with the SB/PS/Dac combo. I am thinking of getting a 100ft ethernet cable to connect direct to computer (router) rather than wireless, as I have heard that will upgrade sound as well. Has anyone tried this with the Squeeze Box?

Cerrot,

you just made me wanna get a benchmark again! Did you used the CI VDC 9.0 for the SB? or did you upgraded the PS for the benchmark? or both?

You'll be very happy with the Benchmark. I was truly surprised at the performance for the money. I upgraded the squeezebox power supply with the CI. The Benchmark goes into a Shunyata Hydra 8 with a Shunyata Python helix Vx power cord, which was a pretty nice upgrade itself.
