Advice on power conditioner

I would strongly agree with Sean concerning the Chris VH power cords. I have put together a mix of models numbering about 16 of these, and tried them on a host of different equipment, all with great results. If Ernie has put together a kit with all of the parts, so much the better for you.

Regarding the Richard Gray units, I had three of them. They strangled my amp. My Pass X350 and my Rowland Model 10 sounded like tiny triodes. When my A/C kicked on, the 60-watt lamp I had plugged into one of the units dimmed. So much for incredible power reserves. The Monster is better for lots less money.

No doubt about it -- Monster 2000 (or the latest model #) is the way to go. Online, you can find it for around $130 or so. Also, I would say plug the amp into it -- I live in Manhattan and the sound improved substantially with the amp plugged in. Also, no need to use the so-called high current outlets in the unit -- they don't handle any higher power but do have less filtration. But, in NYC you want more filtration, not less.

Concur with the Chang Lightspeed recommendation: probably the 2500 would do the job just fine for an integrated, but if it's a high output unit then maybe go for a 6400. Stereophile recommended, neutral character, contains integral MOV line-transient protection. Used-priced on Audiogon it's a no-brainer.
Try the amp with upgrade cord both ways - straight into the wall & then through the Chang, even trying out the different levels of filtration (digital level filter vs. analog level filter). The 2500 MKI's two digital outlets are unfiltered yet are transient protected, the 2500 MKII's digital outlets are filtered & the analog outlets are filtered somewhat more, all with transient protection.
