Another MC402 Question

I sold my Mc402, I could not find a system that it worked with. I think the transformer output just made all the loudspeakers I had sound flat. Replaced with a Parasound A21, much much better. 

I have had my 402 since 2008 and have been very happy with it. I am driving SF Olympica Nova III’s as well. I have used this amp with Audio Research LS26, REF 5se, Ayre KX5 twenty (very short time) and now LS28SE. I would like to step up to mono blocks, but not in the credit cards right now. I think you can’t go wrong with the MC402 and if you’re not satisfied, there seems to always be a buyer for them.

Theo, you progressed from REF5SE to LS28SE. Can you describe the difference between the two? I’m thinking of upgrading to the LS28SE.

Fundsgon, (love the moniker) I had wanted to transition back to solid state or I would have kept the REF5se. But when I decided to go back I couldn’t afford a REF6, and although I am sure that the REF6 is far superior to The LS28SE, I am very happy with my purchase. In comparison the REF5SE presented a more defined deeper bass and maybe a more delicate mid range. But that said, the LS28SE is still breaking in, roughly 400 hours and only 200 on two of tubes. I had one tube fail and Audio Research sent me 2 and they are still breaking in. I am also breaking in the speakers and it is hard to say which is to credited with  what I am hearing, but it is amazing the transition of the sq in the past few weeks. So in my opinion the LS28SE is right on par with the REF5SE. Yes there are differences, but I can’t honestly say if it is the speakers, the pre amp of both have just developed a perfect synergy. In short I am not looking back.

I ran 2 Mc402 amps with my Khorns and LaScalas for  quite awhile. When I first bought them they were paired with an Accuphase c-3800 preamp and sounded dry and lifeless to me, Which is hard to do with 4 Klipsch Heritage speakers.. The Accuphase had been my go to for a long time and I was pretty attached to it. Thought about other amps but decided to get a Mac C51 pre and try the synergy thing. Everything really brightened up with the C51 and I ended up loving the Big Macs. So in my experience the 402's were pretty amazing when paired with a certain preamp. Now I run 2 Mc252 amps with the same C51 and am loving every listen. Go Mcintosh!
