Keep it clean...

I use a PS Audio P3 but have been told to ditch it & just use a high quality distribution block i.e.- Furutech, GutWire, Argento etc.
The argument is that even though the P3 & similar products produce clean power with apparently no restriction to the sound, there is still some compression. Additionally the use of such devices determines which components are used due to wattage limitations applied to these products.
