Good upgrade from Levinson 33H's


I have been reading discussions on here and in audio reviews, looking for a good upgrade from my Levinson 33H's. First off, these are the best amps I have heard, but I have not heard many of the new wonder amps discussed on many threads here. I am running all Stealth cable, with the Genesis 4 tower speakers.....so the amp I choose to upgrade to, will be running only my Mids / Tweeters. Some, but not all, that I have interest in are, BAT, Joule, Lamm, MBL,CAT,Atma-sphere, Soulution......generally the usual suspects. Each seems to have it's good and bad points, or rather, supporters and critiques, probably depending on many occassions to what supporting equipment people may be using. I guess the bottom line here for me is, which amps in this list or not, would be a substantial upgrade from my Levinson 33H's.......I don't want a lateral move! To all those that will say.....you have to audition....and what do you like or what are you looking for....yes of course. However, without traveling the continent to audition them all in someone elses system, what should my short list be? Thanks in advance for sharing your experiences.

Yeah, I hear you loud and clear French Fries......I have no issue keeping them, the fact that I don't know how they compare to the "new and improved" stuff peaks my curiosity! I'm sure I would have to spend tons to get a serious upgrade. I do love my 33Hs. I am going to try that voltage thing, see what happens.
well i AM going to try a ps audio soloist premier (the thing that goes into the wall with the upgraded black outlet that got a favorable review) to feed the amps. a rep at ps audio assured me that it does not limit current. even though the amplifiers regenerate A/C internally i did read a comment or two in the forums that the 33's and 33h's benefitted from well-designed (and of course non-current limiting) devices that reduce A/C noise upstream from the amps themselves. Plus with numerous brown-outs and brief but annoying power interruptions common to the area where i live, Some form of Protection would seem better than the "direct-to-the-wall" approach. it will be interesting if i hear any differences in the sound, although my expectations are understandably pretty low...
Well, after much thought,reading, emails and discussion I have jumped onboard the Tripoint Troy bandwagon, so to speak! I have one on order and it should be here in the next couple of days! Pretty excited about it, and I will report back after I have it in the system and perhaps after a few weeks of use, as they say it gets better after about 3 weeks.

Also, I have upgraded the outlets with Maestro, made sure all outlets were on the same phase, and have a dedicated breaker panel. Love the Maestro!
Still no Troy, customs issue with Fedex! Hopefully it will be here tomorrow. I also needed two extra ground cables that Miguel is sending........so as soon as it is all here and hooked up I will give an initial report and perhaps a few other reports if things take a drastic change as it settles in.
