Having a quality power supply is a big part of getting better sound quality. A lot of the amps people speak of in these forums use some kind of outboard power supply and to be honest I cant remember reading a post where is was not an improvement when upgrading the power supply. Hopefully someone who has used this power supply can chime in.

I have both (the Supplier and the Fubar II), and, yes, it makes a difference, and I feel it is worth it. If you can use it with a Fubar II or an amp (and you have only one), then I'd suggest seeing with which component the power supply would make the most difference in your particular setup.

I used the Supplier with the Fubar and the Spitfire DAC as well as the Cute Beyond.
I found it a useful addition to all three.

A power supply upgrade usually means that there is more power for your euipment to operate better.

IMO, the best way to lower floor noise is a better power section, especially because everything is checked relatoive to ground. Everything should run much more stable too since it won't have to work hard to get what it needs. Less stress on your components is a 100% plus.

You will find that many high end amp manufacturers put as much time and effort into the power sections as the amp sections. I believe that Mikail was even quoted as saying that amplifiers are basically beefed up power supplies for headphones. Analogue seems more power dependent though because there isn't stuff like parity bits to do data checking and correction.

Though from my experiece and other peoples comments, some things and pieces of equipment scale better than others.

I just got my supplier today and I heard the difference immediately.

I don't know if it applies to everyone else, I'm suspecting one of the reasons I hear a difference is because the power regulation in NYC is horrible, so something like this helps it play "quieter" and more effective.

Worth it but if you have good efficient power (read: anywhere but here), you might not notice it.

Now I have to change the power cords on my speakers . . . that might be a while.

I've used the Firestone Cute Beyond amp without supplier for a couple of months and I finally decided to order the Supplier earlier this week, even though I had a feeling it would be tantamount to throwing money out the window (around $150 from the, I believe, only Danish store with Firestone products. 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 have the supplier hooked up to my fubar3 and it made a huge difference imo the noise floor is dead silent and it added punch to the bass as well as opened up the mid range and treble. I love this combination plus they look great together. My set up is Black Macbook>black fubar3 usb dac/headphone amp with black power supplier>headphones or audioengine 2 black speakers. It sounds awesome to my ears and those little speakers really sing when they have a good signal to them.
