Amp is plugged to the wall, why use a conditioner?

here is my recent experience, fwiw: originally I plugged both my mono Jungson JA-50 80 watt class A amps into my Shunyata Hydra, along with just about everything else. In my wall I have two sets of outlets, both high end receptacles, one running off a 15 amp breaker along with other outlets, switches etc on that end of the house. The other outlet is a 20 watt high end outlet wired to a separate dedicated 20 amp breaker with 10 ga romex. I believe the standard house romex is 12 ga. Recently I unplugged the amps from the Shunyata and plugged them directly into the dedicated 20 amp circuit. Couple observations: the amps sound much more powerful and I don't have to push the volume knobs up nearly as far on the pre-amp as I used to. The bass is better and the system sounds fuller, less constrained, and less 'pushed'. I've considered buying more powerful amps for my Khorus X mk II's but no longer feel that is in any way necessary.

Markmendenhall, I had a similar revelation last year after directly plugging everything into the wall outlets. It restored tone, current ... just sounds more natural but downside is hearing noise.

I discovered Weizhi PRS-6 passive from a local audiophile. It eliminated the noise and doesn't alter the tone or limit current ... just sounds fabulous. I have 2 PRS-6, one for mono amps and other for rest of components. Also have 2 dedicated 20 amp circuits with Maestro outlets.

Glad to hear you've solved both the current and noise issues. I must consider myself lucky, for whatever reason I don't have noise issues plugging the amps directly into the wall outlet. Everything else runs through the Shunyata conditioner, I believe the amps require the most current to operate at peak efficiency, compared to the pre, CD player, TT, etc.

My Adcom ACE 515 I bought new about 127 years ago keeps on truckin'. I run everything from it including a PS Audio Humbuster III that the 2 amps (a tube amp for main listening and a rarely used SS for outdoor deck entertainment). I did stick PS Power Ports in the wall...so there's that...I might be fooling myself into thinking my system sounds amazingly good, but hey...it does. I tried plugging the main tube amp in the wall but heard no difference, and the Humbuster at least makes it look like I care...and I do care...sort of...

Markmendenhall, the problem with noise is you don't realize it exist until removed.

I had friends over and 2 have high efficiency horns so familiar with noise. They heard excessive noise with my amps plug into the wall and one suggested Weizhi. His friend has a Shindo system and got off the bus with Weizhi.

We have all different systems and taste but try Weizhi if you have a chance.
