Any SB Owners Using Channel Islands Power Supply

Look Here to see what I am referring to. Since my server has become my main source for listening to music, I want to maximize its performance (sound familiar) – this looks like an interesting tweak. I’ve read good reviews about the various CI High Current Power Supplies – I’ve even read some highly positive reviews about the Duet/VDC-9.0 combination. That said, I have also read several threads on the Logitech site that are emphatic that an aftermarket power supply cannot improve the sound quality of any SB device (this coming from several senior members, including the Logitech top honcho). I know we’ve all thrown a meager $279 to the audio Gods to no avail, so this isn’t that big a deal. Then again…$279 will buy all my little cherubs new shoes. What say those in the know? I do prefer unabashed knowledge, but I will certainly welcome sarcasm, cynicism and mildly offensive humor.

Thanks for the input. I just ordered the CI Audio VDC-9.0. I'm anxious to plug it in this weekend.

Will do. Anyone try the other Bolder mods on their SB3's Duets, etc.???

I've got the Bolder Cable digital mod. Again, definitely a step up from the stock unit. Quieter, smoother, etc.

Did you upgrade the PS at the same time you had the digital mod done? The reason I ask, is that I wonder if the improvements you hear result more from the internal mods rather than from the upgraded PS. Hopefully I'll gain some improvement by just upgrading the PS. I'd hate to be without my Duet receiver for very long. How long were you without your receiver when you had Bolder do the mods? I wonder if Cullen Circuits does any mods to Logitech devices??

Thanks Ecruz. There are a lot of naysayers regarding after market power supplies making any audible improvements in SB/Duet performance (aren't there always). I have also found that many an audiophile have been blessed with far more “golden ears" than I. Are you a golden-eared one, or was the audible difference, in which you refer, noticeable to mere mortals??!!

Again, thanks.

Is anyone using these mods with digital out to external DAC, or is everyone using analogue out to preamp/receiver?

I am using digital to DAC - I'm assuming the others are too, as that is the optimal option. If I read your thoughts correctly, you may be wondering if the inclusion of an aftermarket PS will actually improve upon the digital output. I am wondering the same thing – since I’ve read that replacing the stock PS will have greater affect on the analog outs (albeit still not a match for the digital out to DAC methodology). I'll be able to provide an unbiased review once I add the power supply this weekend.

(get the upgraded power umbilical also).

Where did you get yours? Did you get the Revelation Audio Lab Silver umbilical, or one from CI? What are you using for the AC Power cable?
