Levinson 33H vs Boulder 1060/2060??

I apologize for not addressing your question, but take the liberty of seconding what AudioOracle wrote, specifically, that there are other solid-state amps which meet or exceed the sound quality of the Levinson 33H and Boulder amps. If the speakers do not require tons of power, I suggest that you begin your search with the darTZeel (... which is where you may very possibly end your search). For high-powered amps, the Edge amps that AudioOracle sells will often outperform Levinson or Boulder. For that matter, the top Lamm, Gryphon and FM Acoustic amps should all be considered. Classic Rowland (Models 2/6/8ti/9ti) is more than competitive with 33H and Boulder-caliber solid-state amps. Levinson and Boulder are well built and have historically maintained their value, but, in my opinion, they tend to sound like hi-fi, while the very best solid-state sounds like music. In short, you may want to widen the field of contenders.

FYI, I agree (mostly) with Raquel's assessment of the amps mentioned.

I am a little kinder towards the Mark Levinson amps, since I used to own a couple (and have fond memories of them!). I believe they are really good solid state amps. However in my opinion, they lack a bit of soul, (which I define as that organic quality that really brings the music to life. Feel free to call it what you will!) However, I have not heard the 33H, and it might just have it.

I also agree that if you truly want a really great amp, both the DarTZeel and the Lamm amps have soul. Personally, I prefer the Lamm amps, however, the DarTZeel is pretty extraordinary for a true solid state amp. (The Lamm amps I directly compared it against was a hybrid amp, that had one (6922) tube in each monoblock.) I felt that the Lamm had just a bit more bloom to the mid-range, and the treble seems a bit better as well. (It was difficult to compare the bass response, as the Lamm had 220 wpc (in two monoblocks) vs. the DarTZeel's 100 wpc, (in a stereo amp), so it was not quite fair to compare the two. The DarTZeel had good bass, but the Lamm was clearly better, however this was using Rockport Antares speakers, which is truly a full range speaker, as the bass response goes all the way down to 20 hz. That 13 inch woofer demands power, and the DarTZeel gives a good account of itself, but in the end it just ran out of juice.) If your speakers are more efficient and/or sensitive than the Antares, it might work just fine for you.

My two cents worth anyway.

i agree with Raquel and Kurt. i've owned three Mark Levinson amps; the #335, #33H and the #33. i enjoyed them all, likely the most musical was the #33H.....which while short of the effortlessness of the monster #33, was a bit less 'processed' sounding.....always listenable.

i've only listened to the Boulder (both 1060 and 2060) in unfamiliar systems....but i've heard them quite a few times on familiar speakers. they really do nothing wrong and have low distortion and are not sterile sounding. OTOH i have never been drawn into the music with Boulder and always get that processed sense more like the big #33 Levinson....maybe all those circuts and output devices.

for me the darTZeel is the one; but i agree it does need a reasonable load to be fully dynamic. on my 93db Evolution Accoustics MM3's they do everything one could ask in my very large well damped room. the MM3's do have powered subwoofer/woofers so the dart only powers the mids and tweeters. i've heard the dart on full range speakers in normal sized rooms and they do just fine.

the dart does not sound like ss or tubes; it sounds like music...sweet, detailed, natural, low noise floor, great micro-dynamics, very articulate bass, and a texturally rich and pure mid-range.

the Lamms are different from the dart but also are quite good (i prefer the dart personally).

i have yet to hear a mega-watt ss amp that i could live with long term.

YMMV

I would also add to your listening list the ASR Emitter Exclusive along with the Darts. I have listened to the Darts at Mike L house and they truely are fantastic. My ASR is also in the same league. Either of these amps will give you tremendous listing pleasure. It really depends on your speakers and the rest of your equipment/enviroment.
I own both 33s and 33h's. I prefer the 33 to the 33h but over all the ASR is more musical.
Good luck.

well, to turn the coin over for a moment, the dartzeel amp offers a reportedly lovely voice, but only comes in one color (i mean one size of course). one preamp also, which is prohibitively expensive (10-15 grand oughta distinguish between two strad violins made 3 years apart). but i'm just as big a phool as anyone, and truly great sound is what it is.
so get a tivoli radio and get 92% of the 33h's performance or 90% of the dart's. i'll keep reading and learning from these discussions nonetheless. thanks to all.
