The Levinson 33h? Pros and cons?


I was wondering how the 33h holds up against the competition?
I am considering purchasing a pair, but am unsure if they will meet the demands of my Revel Salons. I believe that the 33h will in fact sound better than the Levinson 436 series (they are Levinson's current Reference since the 33s were discontinued), but I'm biamping (maybe triamping if you count the pair of Revel Sub 30s I'm using also)and with the double pair of 436s I never run out of power. There is no current way for me to hear a pair of 33hs in my system or for that matter for me to hear a pair thus the deleimma. See my system for more info.

You may have a bit more headroom if you are bi-amping with four 400 series amps, but the 33H (and 33) use power regeneration, and feature better parts quality than the roughly half the price 400 series (the 33H and 33 were designed and made at the zenith of the two-channel market in the mid/late 90's -- Madrigal, like most other manufacturers trying to survive and profit in a market that is now 90% home theater, moved to more affordable, more compact, home theater-friendly amps with the 400 series). If your system is primarily used for home theater, then there is no need for 33H's. On the other hand, if your system is primarily for music, the 33H should be better.

I run my Salons with 130 watt/channel triode tube amps (VAC 140/140 Mk. III's). The best sound I have ever heard from Salons is my friend's pair, which is powered by CAT JL-1 Limited Edition tube monoblocks. Of course, very few tube amps will drive Salons properly due to their low impedence in the bass -- solid-state is much safer with these speakers.
I own Studios, and have since 2001 or so (with a short break in 2003). I've spent a lot of time listening to Revels with various amps, and have heard them with a wide variety of Madrigal gear (Proceed AMP5, ML 336,33H,33,43x), Krell (from the integrated up to the latest FPB), Aragon, Music Reference, Linn, and most recently, Lamm. I use the Lamm M2.1s (200wpc hybrid monos) on my Studios now, and they are by far the best I've heard. As long as I'm using a non-SET friendly speaker, my amplifier of choice will be the hybrid Lamms.
Just bought a pair of 33’h amps. Replaced the 436. The 436 is not even in the same league as the 33h. I still like the 436’s they served me well for years with the exception of having to get the vg board replaced in one amp. These 33’hs are bar none the best amps I have ever heard in my life. I Haven’t had the pleasure of hearing the 33.  I have also auditioned the 53’s, they were very fast but too analytical and bright sounding for my taste.

what are the price points of No. 33h, 53, 436 amps ?
Happy Listening!
My concern with the 33H amps would be did they use the same problematic capacitors as used in the 300 series amplifiers.
