Mark Levinson 333.5 vs Emotiva XPR-1 Monoblocks

I wouldn't say *extremely* hot but yes, very warm to hot.

I did own the no. 23 amp from '88 until '92. It was ok, but I found much better.

Never owned Lamm.

bo1972  - you're so full of it !!!  Never heard such a blatant BS in my life !
What is it with you and Pass Labs ? A good discount or a kickback?
I've heard them ..and compared them to ML and other amps. Some were  good, some were NOT at all ! And even a lesser Emotiva pair - XPA-1 Gen 2, not the XPRs  mopped the floor with a Pass Lab amp on one occasion ( with B&W 802 ).  
And to say the 800-s B&Ws don't sound good with ML 33s - that's really brilliant !! Considering that B&W as a company uses these monoblocks as their reference amps !  That , obviously, eluded you. However, these amps  do need to be properly fed which requires  A LOT of power. There's so much more to a good sounding system than just switching components ...but , as I see, you know nothing about it. 

Mark levinson and "emo" should never even be spoken in the same sentence.  Keep the levinson, and forget the other Chinese amps. 

Poor parts, poor amplifiers.   

There is no comparison, levinson all day long. Better design, better parts, better in every aspect! 

I own the gen 1 xpa-1 monos. 

 I had my Sunfire sig refurbished by Bill flannery, and did compare them, the Sunfire stereo amp embarrassed the emo amps, was not close!  The Sunfire amp is from 1996, the emo monos from 2008. 

Keep  the mark levinson amps, you will thank everyone later. 

As mentioned, get the 30 day trial, u will send them back. 

Comparing the quality of Emotiva to Mark Levinson would be like comparing a Kia to a Rolls Royce.
