Great first response but let's pretend it is a pristine split rear window Corvette Stingray owned by a local business executive and not the MVP award winner from the Yankees (who is selling his car at Christies'). By the way, does AC have a lock on the market for vintage collectibles like this?
[Tom Manley] has had those Mc240s forever. It goes to show their desirability. You can buy clean ones all day on ebay for $2.5K. Why? The sound stinks.
until the wee hours in the morning - a good part of that time trying to understand how somebody could dislike this amplifier so intensely. :headscrat:headscrat:headscrat CountD,
I have infinite respect for your views, opinions & expertise regarding McIntosh.
*If by chance you are ever in the area, I would very much enjoy having you over my house where together, we could do some serious A/Bing between the MC 2505 and MC 240, where your firsthand critiques, comments & observations would be most welcome!
Best, Eric
but last night I decided to run the 240 which I enjoyeduntil the wee hours in the morning - a good part of that time trying to understand how somebody could dislike this amplifier so intensely. :headscrat:headscrat:headscrat
And to answer your question about why I dislike the Mc240 so intensely is because it really, honestly does not sound like a McIntosh. I have no idea why the Mc275 and Mc240 are at complete ends of the sound spectrum when 1) They are from the same period, and 2) They were engineered and made by the same people.
I guess in some ways I feel ripped off that they went from the legendary, nice sounding Mc30s (notice I said nice, as I have owned a few pair), to the fantastic and stupendous sounding Mc60s (which are absolutely fantastic), to the Mc40/Mc240 and the Mc275. The Mc275 holds up. The Mc240 doesn't when compared to these legendary Mc products. It just doesn't, and anyone who had one and had the others and listened to them, they probably would agree. Just because they sold more means nothing. It was what was available, and the Mc275 was that much more. It looked the same as the 275, and 40 watts at the time was tremendously huge.
So to answer your question again, the Mc240 is probably better than other companies offerings at the time, but compared to Mcs offerings, it doesn't hold.
so what do you think about the mc225? :scratch2:
Does the MC240 have the Unity Coupled output transformer?
If not, then that my explain it?

Yup!
MC 30 and MC 60 have the distinction of being the only models with tube rectifier while MC 40, MC 75, MC 225/240/275 are solid state.
Why they did that, and what role it plays in sonics (if any) - I have no idea...![]()
Right on. I would like to come over to check them out at your place in the new year now that I'm on the east coast. I have played the 240 and 40 beside the 250/2505 and they were lacking. But it may have been the units.
After awhile I noticed that MC225's and (especially) MC275's went fast and for high prices. MC240's just sort of came and went for prices that seemed low compared with its two contemporaries. You begin to wonder what the issue is..
Not everyone has a golden ear, some just had money to spend on a nice living room stereo. After awhile I think it developed a reputation based on customers going up or down in price or power leaving the 240 as the odd man in the middle.

pretty sure they were tube rectified because solid state diodes weren't readily available or were cost prohibitive
