What attracted me to the BVaudio P1 was their implimentation of designs that got rid of conventional thinking volume pots. I have owned various active (Klyne 7.3LXB, Modulous 3A- moded, CJ PV 12- also moded/NOS tubes, various passive units including autoformer based dual mono designs. The BVaudio P1 is a breath of fresh aire in my system, and unlike many of the ones I've owned, the price is very blue collar. Another nice feature of the P1 is that it incorportes BVaudio's Sound Refiner SR 10 circuit, allowing you to mix amps without notorious impedence problems. The remote also includes a handy mute switch, plus you have a near infinite control of volume.
The best place to make a decision is in your own system. If you try one, I doubt you'll return it.
Someone posted that I am a BV dealer, true enough (it is a part of my signature), however that should give more credibility to my comments because I have owned, and have access to a wide variety of products. I have happily settled in with BV amp/ preamp, and SR 10s.
Last Friday I added the latest version of the Xindak SCD-2 (tube output), replacing my Sony DVP 9000 ES, and became even more impressed with my BV kit!
