Who heard the Mark levinson 53 monos?

I finally herd the allusive 53 s in the Harman truck , ( called sound that stirs the soul ) . The bass in a converted tractor trailer was less than optimal , but in my personal opinion the 53, Salon combo was the best I have heard , bar none .But I dont think a 2 hour demo qualifyes me to make A purchasing decision of this magnitude . In the back half of the Harman event truck they had A JBL synthesis home theater system , oh my god , Im A strict 2 channel guy , but what I heard there totally blew me away . Any audiophile worth his salt must seek out the Harman event truck and give it a listen , its unforgetable . MAX

Thanks tmsorosk , I suppose getting the sound right in a truck will be a challenge , i just made a offer on a 5 year old ML 32(phono) / 33 H combo which i want to have also in my system one time sooner or later .

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.
