I have done a couple deals with Dave as well as Pete. To say that I am very pleased would be a massive under statement..
I have went through the wringer with different power conditioners and isolation transformers. The conditioners I tried did some good for the digital equipment, but killed the amps. The isolation route was better, but still something was missing, and it colored the sound a little too much for my tastes.
I contacted Dave, and he assured me that my system would come alive with an UberBuss. So, I said make me one as good as you can. He loaded it with a powercon inlet and Furrytech outlets. He also threw something in to help isolate one of the recepts for the digital equipment. I also got one of the Mongo power cables as well as Pete's Triode Wire Labs 7 Plus to try.
After installing the Buss, I could immediately tell it was special. It did one thing, and did it better than anything else I have tried. Noise in my system fell like a sink hole. Things came alive, and it did in no way color the sound or rob dynamics. Dynamics actually improved across the board. Think of this as a system upgrade. You will not know what it is capable of till you get the noise out of the equation. Particularly digital equipment. I find that it thrives on clean power to make right. I'll even go as far as saying that the UberBuss will do no wrong to any system, only improve it.
Trying the Mongo first, I found this cable to be utterly transparent, very dynamic, with no color. This is the closest to no cable I have ever heard. So clear and transparent are what it does. It tells you what you have in the system perfectly.
Pete's cable is also exemplary. It pulls off the smooth yet detailed thing better than anything else I have tried, and that ultra clear transparency is there also. They both soundstage the same and bass slam is also equal. Each of these power cables represent what power cables should be, without all the extra overcharge. I really can't recommend one over the other for the UberBuss... It will boil down to costs and what you are trying to accomplish.
Living with the Uber for close to a year, my components expanded and I needed more outlets. I contacted Dave again and he said the MiniBuss works well plugged into the UberBuss. Providing extra outlets and extra filtering. Taking his word immediately, I had him build me one with a powercon inlet and more Furrytech recepts. I have now had that for a few days, and all I can say is WOW! I am now using the UberBuss for the amps and all the analog equipment, and the Mini for all the digital stuff. This took the system up yet another few notches making the system quieter yet and much more musical. Still, did not rob dynamics or color the sound in any way. I tried it first with the Mongo feeding the Uber, and the 7 Plus feeding the Mini. This was good. Then I switched the power cables, running the 7 Plus to the Uber, and the Mongo to the Mini. This was a holy shit moment. My digital stuff LOVES the Mongo/MiniBuss combo, and the analog stuff LOVES the 7 Plus/Uberbuss! It was like, Ahhh...
Each step was an improvement with no detriment to the sound in any way. That speaks volumes about this stuff, and I doubt it gets better for any money. Just so very pleased to have found these guys. They helped me make my system sing the way I thought it should.
I have also became great friends with both of these guys and they are both the most honest and fair individuals that I have met, with great sense of humor. They are not in it for the money "only" as far as I am concerned. Weighing the cost to performance, there is no way they can be. They are just a couple good ol boys that I highly recommend dealing with, that sell excellent products. Plain and simple.
They both offer a return policy if you are not satisfied, and I doubt they have had many returns for anything. My system without these products turn into nearly unlistenable. They are that good.
