BPT 3.5 & SP Owners

The BPT is DEAD quiet. You cannot here it. Most people use it for their front end. I believe you get the most bang for the buck on the front end.

I never had any noise problems or bad hum with my 3.5 either. Not audible at all from the listening area 10 ft away, and barely noticeable from 3-4 ft next to it. It worked extremely well with my front-end, and I had added benefits when running my VAC Phi 30/30 amp on it. No current limiting problems or loss of dynamics like I had with some other balanced line conditioners with the same amp.

Chris makes some very fine power cables - I would talk to him about the long run

First let me say I think the 3.5 is one of the top power conditioners out there. Second, I have run several different power amps through my 3.5 signature and I thought it was beneficial. More black backgrounds, definitely lowers the noise floor.

But, yes, I experienced hum during certain times of the day or night when it is dealing with dirty power. The level of hum varied with how dirty the incoming power was and therefore how hard it was working. When humming, it was audible from the listening position about 12 feet, but only if no music was playing. With music playing it was too low in level to hear. And, just to be clear, often times there was no audible hum. I had another balanced pc before the BPT and it hummed all the time and sometimes could be heard during quiet passages. I bought the BPT to replace it and there was simply no comparison.

It is an excellent product.
