The hard core audio heads I know with decent power avoid any filtration since it effects the sound...OR, their power is so bad, they come up with the least of the evils. I am in the latter camp but my power treatment ended up being a load of money!
I needed regeneration since my voltage would be higher or lower for long periods. This effected my Decware tube amps, higher voltage giving a thicker, mirkier sound, and lower, a leaner, brighter sound.
I went for years with an Audio Brickwall though which was relatively transparent and protected against surges (but not a sequencing unit). Also added some power line noise grabbers for cleaning high frequency RF and EMFs. But finally the voltage thing just beat me, so my resistance to the big-bucks solutions faltered.
PSAudio regenerators can be set for slow start. Though I don't think this is a common response, my P5 for me was a notable downgrade other than the voltage stability. Veiled and a little unnatural sounding. It took a lot of experimentation and burn in to make it as transparent as I wanted. A really good homemade power cord and the right feet did a lot toward solving this, and finally voltage and Phase setting adjustments.
Also to get where I wanted, I could not run my DAC through the P5 (even with it fixed up!)...it deadened the DAC too much, requiring a more complex system...some gear through the PSAudio P5 and some through the Brickwall with a Shunyata Defender for an added filter.
But most say their PSAudio gear is great!
You can get good deals on open boxes (I prefer them because most give them up before they are burned in fully, but at least suffered part of the burnin for me!) May be more than you want, but there are a few threads here about them and other power treatment if you want to check it out.
