I can’t praise Eaton Power Quality data Center UPS products highly enough. There is a marked difference between these on line double-conversion UPSs and substandard SOHO units. I use the Eaton Powerware 9130, which produces a pure, clean sine wave output, and can give detailed reports about utility power quality and of course load levels and runtime. The only downside is that these UPSs are fan cooled, and therefore cannot be used in the listening area. I have my units in the basement, freeding a sub panel that serves dedicated branch circuits to my system. 
Well, that should probably be extremely high quality components when we have a current like that. I didn't try Gryphon or Lamm in my place, this would be interesting.
Elizabeth, that's good to know. I think some turntable motors dislike changed frequency as well.
Interesting topic !! I jumped in higher end after 20 years of smaller experiments with audio gear. I am one who is using the latest PS audio P20 with the following gear:
ARC preamp ref 6
ARC phonostage ref 3
ARC power amps 150se
LINN Klimax DS
LINN klimax turntable
Sonus faber Amati

Before I hooked up the system with P20 all the above system was on Nordost platform which was QX4, QRT, QB and the Qkore. My cables are Nordost V2 and Odin2. 
I must say Elizabeth comments on tube amplifiers with regenerates is fully noted and its seem correct.
I had notice able differences between the Nordost and P20 setup. I personally preferred  the Nordost setup where the bass and tonabilty with soundstage was much better than the P20. I am surprised and it left me with a hole in my pocket. Over where I am residing in Asia  there is no free testing period....only 1hr of listening the most.
Anyway the P20 is still new with some 4hrs or so and the entire system is under 150hrs of operation since installed. It is definitely premature to gauge however this is my current predicament and assessment. 
I dont know what to expect and at the moment I am not sure which way to go.
Confused.... any suggestions?
