Line conditioner...

I don’t think they give you better sound, unless you have problem to begin with, nor do I think they choke things off if you have a good power supply in your gear to begin with.

Second, I’ve never used one to make gear sound better.
I use them for safety, protection, and maintenance.

No need to give up any of the three, and all lead to a better more reliable sound, for a LONG time...

If you turn on your system, the source is a good CD/SACD, well made, with a good power supply. Turn the volume all the way up, with nothing playing.
My system you hear NOTHING, no noise anywhere, from the tweeters, the mids, the bass drivers, the subs, every source of noise is gone. pure silence!

There is a few thing powered up too, 7 power amps, Preamp, Active OXO, TT (sometimes), Sdac x 2 , Streem, TV, and MC

Some settle for a whole lot less and call it good. NO NOISE, ZERO.

BUT

There is a slight hum at the conditioner closer than 2 feet. It goes away, at 25% volume when under load, and stays gone until 85% volume, then returns from 85-100%. If I stay at 100% for 2 seconds, that goes away also. To me that is a NO NOISE system... I have one conditioner in another room, both plugged into the same 20 amp circuit and the same outlet.

I guess you would call that less noise, but not sound better.. Makes me think something is wrong if it sounds better. Why have filter caps on a power supply if it doesn't FILTER very well.. Kinda short in terms, but long in meaning, AY?
