Ted,
You already got a reply back from Dave, but I thought I would chime in as it sounds like I have a similar logistic setup to yours.
I have 3 Classe 400wpc Monoblocks up front along with a HDTV. I plugged these into a Majik Buss. Since the L/R amps are key to all audio (CD, SACD, DVD-A, DVD, TT, Dish), improving the amps sound made a huge improvement to the system. The Majik Buss is not current limiting and my Classe Monoblocks sounded terrific.
Later I upgraded the Majik Buss to an Uber Buss. The amps sounded even better so all the audio in my system was greatly improved again. The Majik Buss is terrific, but the Uber Buss does everything even better.
My main rack is away from my front amps, so I have a seperate buss on them. I started with Majik Buss. Like all the previous reports, the Majik Buss sounded terrific. The Digital equipment especially benefited by being plugged into the Buss. I love my Turntable, but with the Majik Buss, CDs are now very enjoyable.
I had a spare 2nd Majik Buss around (before the release of the Uber Buss), so I daisy chained two Majik Busses for my Source Rack (Processor, Universal Player, Sonos, Dish Box, TT, Bluray Player). The 2nd buss improved the sound and my Digital sources soudned even more natural, had more soundstage depth, deeper and better defined bass.
When the Uber buss was released, I removed the 2 Majik Busses from the Source Rack and tested things with the Uber Buss It sounded very similar. So to answer your question, NO an Uber buss is not overkill for your Source Rack. In fact I highly recommend it.
Regards,
Darrell
So I heard the standard MajikBuss at my place over this weekend. George (zybar) spent the weekend and left last night. I miss the MajikBuss!!

We had it simply plugged into the wall and the Audience Adept Response AR12 plugged into it. The AR12 handles both analog (preamp, TP analog outs, MW 3910 outboard PS) and digital (Transporter, DAC, MW 3910 transport section). The AR12 is a great conditioner, but when used in combination with the MajikBuss my system took on a completely upgraded-every-component kind of feel. Well-recorded cymbal shimmers (like on Yori Hornung Trio's rendition of Walking On The Moon, from the DALI sampler cd) were incredible, beyond what I was used to. And I think we even had it plugged in to "A" accidentally.
Question: I have two very powerful 2 kilowatt Class D Spectron Musician III monoblocks that, if MajikBuss'd, would require a second one as they are at the front of the room. Currently they are plugged into individual Adept Response AR1's which hang on the Tesplaplex wall outlets. To echo Robin, I wouldn't want 20A outlets cuz I love my power cords, but would an UberBuss make more sense there than another MajikBuss? In place of the AR1's (since I could plug both monos into one Buss)? And would an UberBusss be overkill back at the source rack (i.e AR12/MajikBuss setup) vs the MajikBuss I heard? I know I'm asking a barber if I need a haircut
but would like to know where the Uber would improve my source rack. Thx...great product!
