I use one of these and thought they had stopped making the 500W version . I use one in my system and it's surprising how many pieces of equipment can be connected to it . I've had a 37inch plasma TV , an integrated valve amp , a music server/ computer , a Bluray player and a Virginmedia box all connected to this at the same time . Total output used was 67% of available output so plenty of headroom left.
Improves SQ and TV picture and outputs a steady 230V no matter what time of day it is . Mine has a little readout so you can see what's going on . I've just saw this on Mark's site and this is a major bargain IMO . I wouldn't be without mine .
