Mark Levinson 33H vs Musical Fidelity KW Mono Amps

Quick question by a novice: can someone explain why a 150W amp is able to deliver more sonic depth and power than a 1000W amp ?? Moreover, ML 33h good enough to drive my Magnepan 3.6R or do I need to go for the 33?

I bought a pair of Mark Levinson 33h recently and enjoy it a lot. Recently the amp will power off after 30 minutes playing. Can anyone tell me how or where to repair them? Thanks in advance, lan

Give these guys a call. No way would I trust Harmon Kardon Mark Levinson to service a real Madrigal Labs Mark Levinson..One of their lead techs has many years experience servicing Mark Levinson (Madrigal Labs).

Avloverdad,

You must send the amp to Harman America. They will not give out the schematics to anyone on the 33 or 33H amps. I made the mistake of sending one of my 33's to Bill Thalman and he was uanble to pry a schematic out of Harman. Save yourself some money and send it to them. By the way they will replace every part and IIRC they guarantee the repair bill to be capped at 1200 bucks. Make sure that it really is your amp though. It could be your speaker and it could be your power transfomer on your pole. I had a street light that would go out on my pole and it would cause one of my Levinson 33's to go into standby mode.

Hope this helps,

Johnny
