Who heard the Mark levinson 53 monos?

I just noticed this thread and thought I would add some perspective. First, I empathize with those who have had "nightmare-like" experiences with various companies (i.e. Harman). I have had my share of nightmare-like experiences with a variety of different companies which include banks and financial institutions, automotive manufacturers, insurance companies, airlines, and yes...audio manufacturers. I have canceled policies, dropped product lines, and have taken my business elsewhere. In some cases it has led to the demise of the company or product, but in other cases it has led to people's butt's being kicked out the door and has led to the reorganization, restructuring, and the rebirth of a company and/or product line. I believe Harman has realized this and has already taken steps to take the Mark Levinson and Revel brands to the next level. I am personally very impressed by the new ML 500H series amps, but moreover, the new direction these brands are taking under the Harman umbrella. I would also feel some reassurance that they are under Harman. Just take a look at the marketshare and the awesome product offerings available under Harman on the pro audio side. Anyway...just some perspective.

Yes...the 53's sound phenominal! In short...what you will gain from the entire new line up from Levinson (500H series amps on up to the 53's) will be superior performance on ALL accounts. More powerful, more efficient, much cooler, more reliable, etc. I have been a long time Audiogoner for years and have owned and listened to a lot of stuff from tubes to solid state. I also have a degree in music and am a sound engineer. There is no substitute for raw, clean power. Furthermore, heat is a killer in amps or with any electronics for that matter which leads to reliability issues. Lastly, the 53's are not Class D. If you want I can personally send you the white papers on these amps. In the meantime, if you have purchased the 33H's, good luck with them and enjoy. They are great amps, but the 53's are leaps and bounds ahead of them as well as the older, discontinued 33's.
