ML 33h vs 33 vs A-50V on Mbl 101E


Hello Audiogoners,
I am interested in a comparison between the Mark Levinson ML 33h vs the ML 33 vs Accuphase A-50V (bridged in mono mode) to power a pair of mbl 101E loudspeakers. I don't listen too loud (usually 75db, 85db at times but never above 95db) but control is important (all the above amps have beefy specs so seems they will all be fine). I am more interested in sound quality, so if you could rank these three amplifiers on a scale of 1 to 10 (1-being poor, 10-being outstanding), on the following attributes;
1. Transparency
2. Detail
3. Musicality
4. Mid bass power
5. Overall presentation up to 50-w per channel (remember, I don't listen loud)
6. Stage depth
The first three attributes are the most important to me. My room is roughly 22'X29'X10'. System is Mbl preamp and front ends and 20-amp dedicated circuits for the amps and pre. Please remember that the comparison is in powering the mbl 101E. Direct experiences are most highly regarded, individual experiences will be considered. Thank you all in advance for your reply.

I've heard the ML33 and the 33h, but not on MBL's unfortunately.  The 33 was significantly better to my ears.  Truly effortless.

I don't have experience with the A-50V but if it boils down to the 33 and the 33h - go with the 33's.

The numbers below are from memory but I know both of these amps pretty well.

ML33/ML33h

1. Transparency - 9/7
2. Detail - 9/8 (both very good)
3. Musicality - 10/8
4. Mid bass power - 9/7
5. Overall presentation up to 50-w per channel (remember, I don't listen loud) - 10/8
6. Stage depth - 10/8

Good luck with your decision.


The 33 is just better in every way than the 33h from my recollection. I think you'd be smitten with either, but if you're considering the two and budget isn't a concern, then go with the 33's otherwise you will always be wondering...
Why thank you, I appreciate that.  Hope your holidays are great too.  Enjoy your new amp(s), whatever you decide to go with.

*cough* 33's *cough*
