Well, Dave told me I could be a guinea pig for his new entry level power cord, so that's what I am! My thoughts below on the power cord and the ÜberBUSS. (I apologize for the giant post, let's just call it an Über Post)
First of all, Dave is one hell of a guy. Not only is he full of extensive, helpful information, he has some of the best customer service I have ever experienced. He answered all my questions regarding power and audio and helped me customize a BUSS that would work for me and my requirements. Just before it was time to ship my unit, I had sent Dave a message asking about grounding and hum issues, because I had been experiencing some when I got my new pre-amp and amp (Wyred4Sound STP-SE and DAC Cherry Jr). He messaged me back with some helpful information, AND, he said before he shipped my unit, he would customize the BUSS with a grounding switch, that would lift the ground on the top receptacle, so I could lift the ground and see if I could solve my hum issue... All of this for free! I was blown away! And on top of that, it did solve my hum issue!
So when my ÜberBUSS box arrived, I opened it up and noticed there was no power cable included. I had asked Dave originally for a power cable because I didn't have any extras at the time. I bought a cheap $15 generic power cable off of him because I didn't want to spend the money on an expensive cable at the time. So when it arrived and there was no power cable, I e-mailed Dave and let him know that he forgot to include the power cable and that it was not a huge issue, but asked if he could ship me the cable or just refund the $15 because it's not a big deal. He e-mailed me back and apologized and gave me an offer... He said he could refund the $15, or ship me a special entry level power cable he has been working on, a projected $99 retail value, for FREE! He just asked me to be a guinea pig and test out the cable for him, and provide feedback. What a guy! I accepted the special power cable, of course.

So back to the ÜberBUSS. I found a generic 14awg power cable in my house somewhere and hooked up the BUSS. I plugged all my gear into (TV, PS3, Sub, Receiver, Amp, Pre-Amp) and proceeded to rock out to some music. My initial impressions were great. Really clean sound, stereo imaging was really good, sound felt like it was coming from beyond the speakers, and I was loving it. It also fixed the hum issue I was having (did some tests and it turned out my sub was causing the issue). Later on that week, I saw some great deals on Pangea power cords and read about how great of a value they are. I have never bought any special kind of power cables before, I have up until now just been using stock cables. I ordered 3 Pangea AC-9 cables, and 2 AC-14SE cables. I put the AC-9 in my receiver, power amp, and ÜberBUSS. And the AC-14SE cables in my subwoofer and pre-amp. I initially just swapped out the generic power cable that was connected to the ÜberBUSS for the AC-9, and I almost shit my pants. I never thought a power cable could make such a huge difference in the sound. The soundstage became huge, sounds were wrapping around my head more than ever, imaging was fantastic and everything sounded more natural than I was ever used to. The second biggest improvement came from changing out the power cable to the pre-amp with the AC-14SE, which cleared up the high freq. a lot and made the music come through more. But enough of Pangea, I just wanted to share my experience with changing out the power cable connected to the ÜberBUSS, because it makes a huge difference in terms of the performance of the BUSS.
So I got the ÜberBUSS on June 4th and Dave's special power cable arrived on June 25th. When I swapped out the AC-9 connected to the BUSS with Dave's special power cable, I immediately noticed a change in the sound. At first it was just different, and perhaps the music seemed to have more "air" to it. But I let the cable break in for a bit before making any comparisons. Around June 28th I e-mailed Dave and told him how freakin' good my system is sounding and it's never sounded this good before. I was listening to Pretty Hate Machine, by Nine Inch Nails at the time (older record, wicked synths), and it has never sounded that good in my life. I didn't know if the ÜberBUSS was fully broken-in, or if Dave's power cord started to break-in, but I was really happy and thought my system sounded better than it ever did.
So today I thought I'd switch back the AC-9 into the BUSS and see how it sounded compared to Dave's special cable. To my surprise, I actually was really impressed as I thought the mid-bass was more prominent and the high freq. a tad smoother and the sound was coming from my entire freakin' wall and imaging was fantastic. I then played a single track a few times to get used to the sound and then switched back to Dave's cable. Dave's cable I believe did seem to add more "air" to the music, but not necessarily separation between the instruments. The high freq. seemed a little more tinny or bright and I wasn't feeling the extended soundstage from the AC-9, but the soundstage was really good but not quite as wide. On some tracks it seemed to help open them up, they sounded less "mudding" from the more prominent high freq. The music had a nice black background, but not quite has black as the AC-9 (if that makes sense, it could all be in my head).
Now, I am currently using Klipsch RB-61 bookshelves for speakers (I have Salk 10" SoundScapes being built as I speak), and some people say Klipsch speakers tend to be bright, so I am not sure if the AC-9 is adding more bloom to the mid-bass and masking the brightness of my speakers (so it is sounding better to me) and Dave's power cable is actually more neutral and is not coloring the signal - but right now I think the AC-9 is a better fit for connecting the BUSS in my system. I haven't tried Dave's cable anywhere else in my system, so it may work great for the pre-amp or amp, we'll see in the next few days. Also to keep things in perspective, the AC-9 is retail $225 for 1.5m, compared against Dave's $99 projected retail value cable.
I did however change out and compare the 14awg stock generic power cable to Dave's special cable, and Dave's cable was hand's down more natural and better in all areas. Soundstage, separation, air, black background, all there and 10 steps above the regular cable. Using the stock cable, I can feel the music coming directly out of the speakers, but with Dave's cable (and the AC-9), the music seemed to come beyond the speakers and if you closed your eyes, you didn't picture two speakers pumping out these sounds. I also tried removing the Squeezebox Touch from the BUSS and putting it on just the surge protector, and there was a huge difference. Overall sound flattened out, lost the soundstage and separation and everything I love about the BUSS. Plugging it back into the BUSS, it was like I got my sweet sweet sound back. I believe a big reason for this is from the poor power supply that comes with the Squeezebox, and I'm sure a linear custom supply would further enhance the output.
I'll experiment more with Dave's cable in different areas in my system in the next few days and see how it goes (could be killer for the pre-amp). It's a great cable and has a great build to it, Dave did a great job. Has a nice tight fit and is really flexible (something the AC-9s have more difficulty with, and is harder to setup since you can't bend it greatly).
Overall, really impressed with the ÜberBUSS, power cable and Dave's amazing custom service. Couldn't be happier and I'm sure I'll be getting some more goodies from Dave as time goes on. Great products Dave, and thank you again for being the honest guy in audio that makes truly quality stuff.

P.S. Don't unplug the ÜberBUSS to see how your system sounded before, it's really painful.
