Does the Mark Levinson 331 suck?

A amp sounds what comes before it. Mismatch the front end then your amp passes what it was fed. A preamp gain impacts sou d quality of it is a mismatched for the amp. I owned the 333.5 years ago and enjoyed it. Was used with the matching preamp the NO 380S, and the speakers were the Dynaudio Confidence 5's. NOT Oracle cables. Was a dam fine sounding system. 

Great reputation. 
 Never a fan of Levinson. Something with the sound, just don’t catch me audibly. 
 The bass seems sluggish, and midrange is not as crunchy as it should be. 
   If you love the amp, enjoy!

18 year old thread

Old thread indeed and another reminder it’s a great amp but the 300 series had bad caps that didn’t aged well and costly to replace. Anyone thinking of buying one should make sure it’s been recapped or buy it dirt cheap.

This is an older thread but, I wanted to chime in anyway. I owed some serious gear in the past 40 years. I do own and listen to a Marsh A400s and A200s, I also tried there preamps but for me they fell a little short. Both marsh amp are excellent amplifiers and do better than much more expensive amplifiers. Mine is paired with a Bryston BP-6 preamp or a Aragon stage one for back up use. The amp is pretty darn close to any Theshold amp, and I love Threshold. The Marsh is very deatiled but lacks just a bit in micro detail. Midrange is very very clear and bass is very good! Not the deepest bass but its just enough. Im not a head banger anyway. Both Marsh ams are very well built and use high quality parts throughout. The A400s is a step up, not just in power but sound quality as well. I do use a Bryston DAC as well. I wouldn’t pony up more money for just a fraction more in sound. ML, Krell, Theshold and others are all extremely nice but at cost! The Marsh amps are a giant killer! Good speed!
