Mcintosh mc 225 vs Marantz model 2's

RetroTodd, welcome to Audiogon!

I haven't ever heard an MC-225 or an 8B. But I know that the 7591 power tube used in the MC-225 is a fine tube, and I'd imagine that it will prove to be quite a nice sounding amp, especially with the substitutions you'll be making.

I did own a pair of Marantz 2's, however, about 20 years ago. As you indicated it is an incredible amp. Around the same time I also owned a pair of the legendary (and these days ultra expensive) Marantz 9's, and the 2's easily outclassed them, especially in triode mode (when paired with speakers that were suitably matched to the relatively limited power capability of the 2's, of course). Although the condition of the particular amps could certainly have been a factor in that difference.

Here is a direct quote about the Marantz 2's from the system description thread of one of our most knowledgeable members, Kirkus:

The best of the vintage amps. Really. ...Sound is clean and detailed, not bright but not at all mushy. Incredible dynamics - better than the 500W/ch solid-state amp they replaced.

What I was most struck by with my 2’s was their richness and accuracy of timbre.

Regarding a comparison between the MC-225 and the 2's, while the following facts are certainly not conclusive of anything they seem worth reflecting upon:

According to information at roger-russell.com, the MC-225 weighs 34 pounds, and cost $198 in the 1960s.

According to literature I have, a pair of Marantz 2 monoblocks weighs a total of 94 pounds, and cost exactly twice that amount in the 1950s, and $440 in the early 1960s.

In any event, assuming it’s in good condition I’m sure you’ll enjoy the new amp.

Thanks for your responce Al. I have been listening to my 225 for about two weeks now. It is freakin amazing. I have only switched the 12ax7 to sylvania gold brand gold pin so far and it sounds fantastic. I will chime in and let you no how the rca 6cg7's sound. Should be a week or so. All i can say is the 225 blows away my mc 30's and 240. Yes the 225 is that good. on a different level than the two.

The 225 is the best Mcintosh vintage tube amp I have experienced. If you can live with 25 watts/ channel.

It is no Marantz 2 though. I have both.

Have fun.

But have you switched the 12au7 to 6cg7 & used sylvania Gold brand Gold pin 5751? This puts this amplifier in a hole different level It will be 25% better.Which is huge!!! Let me know. I would like to here your thoughts on that. I will have mine complete next week. And westinghouse is a must 7591.My guess it will be close to the model 9's. But just a little less than the 2's. Cheers.
