Mcintosh MC2000 owners please help

Velo62 - While I am not a big fan of McIntosh Amps in general, (I think their solid state gear is "just-okay") The MC2000 is certainly an exception to that. It is a very good amp & I have been very happy with mine. The MC2000 responds well to various tube changes and if you use the stock tubes, you are not getting the best out of the amp.

Try using 6 Genalex KT88's and 2 Stock Svetlana KT88's. 4 early Amperex 12AX7's for pretty amazing results. Then change the two 12AT7's to meet your taste. You'll need to roll those tubes (the 12AT7's) trying various brands to find something which suits your system.

The MC2000 responds well to various power cords but given the angle of the IEC outlet, some cords do not work. I use an Electraglide Ultra Khan Statement II on the amp and feel it tightens up the bass and makes the whole package sound more coherent.

In my system the MC2000 drives Wilson Benesch ACT One speakers with 89db efficiency 3 to 6 Ohms very well.

Thanks for your response. Bwhite, for the amperex early runs are you refering to the ones made in holland or germany? What made you decide to mix 2 stock svetlanas in the genalex quads and what benefit is there in doing so? For PC's I have Tara labs and will be using a Xlr cardas golden ref with the C200. Thanks, John

Velo62, the Amperex tubes I use are made in Holland circa 1957.

Running 100% Genalex Gold Lion is nice but I felt it was too much. The sound reached a point where it became too soft and luscious - romantically enticing but perhaps inaccurate.

Substituting two of the Genalex with stock Svetlana's corrected the softness while retaining the benefits of the Genalex. I know it seems odd but its something you have to try for yourself.

Should you use GEC KT88's, they tend to be richer sounding than the Gold Lions and therefore the "mix" to get the right sound from the amp will be more like 2 or 4 GEC and the rest Svetlana.

Thanks Bwhite, did you ever try KT90's. Ive seen many of the MC2000's on sale have swaped out their tubes with the 90's. Regards, John

Hello Aida, the Amati homage was on my list. We have a local chain that carries sonus faber here in fla but only go as high as the cremonas which just wouldnt be enough speaker in my room size. Planning a trip to NYC and will give the Amati's a try along with the Utopias. Another audition Im curious for are the Avante garde Duos. Regards, John
