I treated the analog side of my system. Â I have been progressively treating the connections in my stereo system with the NPS-1260. Â It is a very tiny bottle but seems to go a long way. Â I treated the pins of the phono cartridge, the DIN connector and RCA's of my phono cable. Â I immediately noted increased clarity and space in the sound stage. Â Then after 5 days I treated the two circuit breakers and receptacles of my dedicated power circuits. Â I didn't expect much from that but to my surprise the bass was clearer and tighter. Â I played my Stanley Clark CD which has gobs of bass. Â I know the first track very well because I have been using that track for months to improve my room setup for bass response. Â I heard improvement in the bass playing that CD. Â So in a couple of weeks I will play that track again to look for any changes. Â Overall, this stuff does some good. Â The most noticeable changes to me were the first application to the speaker cables on the amp side, then the phono cables and then the power lines. Â Adding the AQ Niagara Power Conditioner had a much bigger impact, of course. Â The NPS-1260 could be akin to changing out cables with the exception of the 20 amp circuits and the phono cartridge. Â I'm planning to treat the pins on all of my vacuum tubes next. Â It's a lot of work- wah wah...
