Fantastic sounding Hafler DH-220 amp in excellent condition with major mods with upgraded parts, huge torroid transformer - absolutely best $375 amp you will find. PLEASE NOTE: It has a musical concepts sticker on the bottom but neither I nor musical concepts can verify the mods were done by them. So that tells me the mods were done a longtime ago. So please do not call musical concepts about these as they cannot provide information and it is different then the current mods for this amp (which I am sure are excellent!) I have two of these amps and was planning on keeping one- but will sell both for $700 plus shipping and paypal. 115 watts per channel, low impedence MOS FET power amp- built like a tank and easily the equivalent of $1500 plus dollar amps today. Buyer to pay for actual well packed shipping and paypal fee. Local pick up available in the metro Washington DC area. Guaranteed to work fine or money back less shipping charge for 3 days after receipt. Thanks!!
