You might be better off considering PS Audio if you are looking to try a regenerator.
PS Audio is Class D as well, starting with the Premier I think.
From your assertive tone, I'm assuming you're either afilliated or a customer of PS Audio, so I will humbly stand corrected. No Class D there, then.

I am well aware of the reliability problems of some PS Audio models. I did work in CS there and tech support, as well as sales. The older models, P-300, P-600, and P-1000 are all very reliable when used correctly. That is when they are not asked to deliver huge wattage. Unfortunately, PS Audio specifications for their output capabilities were really rather unrealistic. The P-300 is a great unit for powering a couple of solid state source components, or a single tube source (maybe two tube sources if they are lower power draw models), and will run for many years at a load of under 130 watts or so. The P-600 is reliable on loads up to about 400 watts continuous, and the P-1000 is good to about 500 watts continuous. All of these units are probably available used for cheap, and will require a refurb (replacing all electrolytic capacitors will likely be necessary). These units provide great performance and reliability when used within these limitations.
I would not really recommend the Power Plant Premier personally.
Of the new units, I know that the big one is very, very good, and should be reliable as well, as long as it is not overloaded.
One other thing, the PowerPlants need to be treated like the big, powerful, amplifiers which they are. They need plenty of ventilation, so as to not be allowed to overheat, as too much heat kills the capacitors, and will eventually kill the unit itself. I have a P-300 I refurbed and modded, and the thing has been running 24/7 for years running a couple of solid state source components (load around 100 watts). It really is too bad PS Audio often overstated the output power capability of these regenerators, because used within the limits I express here, they really do perform remarkably well.
Yes, it had a (very loud) cooling fan.
It was powering my video setup, a projector, receiver and blue ray player.

I own 2 Pure Power 2000 . Love Them. They replaced 2 PS Audio Power Plant Premiers ( large door stops) The PS Audio units were a big joke (junk) they performed well under par. You can always make use them on your fish tank pump.
My friend also owns a Pure Power 2000 , he has a 63" Plasma TV, Two power amps, and a subwoofer amp feeding off this unit. At 72% percent power output . No noise , and the picture on his TV looks almost 3 D now!
I am not familiar with the Tripoint or Transparent. The Accuphase looks like a very high quality product, as one would expect form that company, but I have no personal experience with it. I think if someone is looking for an active regenerator style power conditioner, and the Accuphase units are within your power needs and budget, that they would be worth an audition.
I am also really interested in the non-traditional "conditioners" from Synergistic and Nordost, as they "work" (or not, lol) by completely different means than any filter or regenerator technology, but I do find it rather dissapointing that neither company really accurately describes what/how they work.
