Only $80 less than the amp itself).

Well, I obviously spent the first few hours after the Supplier arrived doing A-B testing, and with a fairly wide range of music, it was pretty much impossible for me to hear any difference with the Supplier replacing the basic 24V adapter that came with the Cute Beyond.
But then again, I've also been struggling greatly to notice any differences when I've been comparing 320 kbit MP3s (or 256 and arguably even 192 kbit) to the original CD tracks - so I'm guessing I just don't have a very good ear for details (although with regards to MP3 vs. CD I guess it's possible that the DAC in my Playstation 3 is less than great. Though right now I can't really say I'm feeling inclined to take a chance on a DAC as well ).
I suppose it might have something to do with the quality of your power at home. Where I'm at, it's really bad. If my neighbors turn on their AC my lights dim. I had a GL issue I almost gave up on fixing.

I have to use a UPS and something else I bought for the wall socket to help. All of these reasons may be the reason why I noticed a difference. I used my Fubar II without the Supplier for a month as soon as I hooked it up I noticed a difference. I also saw heard difference in an "a and b" test.

P.S. Music is nothing without a good DAC.

Yup, not a toroid, but still worth it's weight in gold as an upgrade.

I also like the supplier. I used the original Supplier to drive my LISA III. It was a cheaper alternative then the one Triad Audio offered and it did an absolutely great job.

Using it with my "I Love Taiwan" DAC + RCA->3.5mm + superlux 688B/Grado M1/Denon D2000

 

Used the stock A/C adapter for a month before plugging in the supplier.

 

There is an audible difference. Whether it is an improvement is a matter of personal preference.

 

Sometimes there is subtle or no difference on with lesser source material (128/160kb MP3), but it improves with better rips (320kb MP3s), and most definite, palpable differences are heard when you use loseless material like FLAC/playing a CD.

 

Better detail separation, more bass punch and  the midrange recess which so irks Denon D2000 sounds less noticeable. More congested, complex music passages/mixes holds better composure.

 

So yes, a worthwhile upgrade for merely US$60.
