Oh No! I found a pair of re-issued MC75s!
Just to complicate my audio life, I jumped at the chance to acquire a pair of pristine MC75 reissues (issued a few years back, and rarely do they come available). I had shared previously in this forum that I was really enjoying my two mono-blocked MC275s, which I found to sound better than a single MC275. Let me now put it this way - anybody wanta' buy a pair of MC275s in great condition?! Amazingly, these MC75s are next level in terms of top end sweetness, overall clarity and soundstage. Others had said as much from their own experience but I had not been in a position to do an A/B comparison until now. I guess the only thing I miss (a little) is the green light show from the two bigger amps firing up along with my C1100 pre - but hey, I'll take substance over form in this case!

Hmmmm….I am enjoying my single MC275MkVI over the mono pair (I sold one a few months ago). I am Jonesing over a MC1502 now. Was tempted by JWJW’s attempt to sell his. A great price.

MC1502 - some are saying it's overkill. I spent the day listening to vocal jazz, rock and country on these MC75s. Absolute gems!

Good question!
Quote:
- The MC275 in its essence was designed to be a stereo amplifier, with the option to mono-block. While good as mono-blocked, it seems to me it takes it a bit out of it's intended zone - especially when compared to the separate MC75s which were designed for the mono-block "purpose". - The tendency is to think of the MC75s as an MC275 chopped in half with a meat cleaver. However, that's simply not the case. The 75s have their own discreet, robust power sources to undergird the sound and, especially, to hold the "bottom end" together, among other things - that is clear from my A/B comparison. The mono-blocked 275s sound "right", but the 75s just sound "righter" to my ears. - Unverified, I understand the re-released MC75s also brought some of the MC2301 technology with them that is not captured in the MC275 VIs. Others probably know more about that than I. - Bottom line, purely from my subjective listening - the mono-blocked 275s are amazing. But context is decisive here in my opinion and all is relative. It is only in listening to the 75s by comparison, which are spectacular, that I conclude the mono 275s are trying to be something they're not quite designed for from the "ground up" like the 75s. This can be a fun discussion. I look forward to feedback from others who are no doubt much more learned and better versed on this topic than I. Cheers, all! |

TorqueBull-
Great catch on the MC 75's. Having heard them along side of a 275 yes, they certainly are a major improvement over the 275. As I am to understand, the power transformer is the same in both amplifiers. So, that same transformer is powering a single channel opposed to two channels. As an aside, I preferred them over the 2301 (with my speakers anyway that are very efficient). Right now, the 275 powers the woofers and the 75's mids and highs. Plan to at some point pull out the 275 and just run the 75's as an experiment. I have tried the 75's on the woofers and 275 mids/highs. While the bass was more defined preferred the sound the other way around. Enjoy those new found treasures!

Great feedback, John. Thanks. I will be very interested in your experience and observations with just the 75s alone vs. your current setup. I was planning to sell both of my 275s now, but before I do, I may have to experiment myself with keeping one to run the woofers like you are.

Thanks, TB--very reasonable hypotheses.
Another though occurred to me from your post mentioning jazz, country, rock. Depending on the type of rock, it may be that your choice of music does not benefit much from the extra power of a pair of 275s vs a pair of 75s. Or maybe you have a powered subwoofer that also makes the extra power less important? Rock on!

Doubling the power adds 3 db of sound. To double the actual amount of sound requires a 30 db increase or 10x; in this case 75 to 750 watts. Solid State does get the woofers going and a powered sub woofer (as you alluded to) may well make a more important difference. Our friend (May He Be Resting In Peace) Dan (AKA JDandy) went from an MC 452 to a pair of 75's and noticed no difference in headroom while more so enjoying the 75's. His thread is still active on this switch; perhaps early 2020 or late 2019. My guess on how much technology from the 2301's was applied to the latest 75's is not much. The 2301's have a "transistorized front end" that contributes to sound differences. I've heard it can be removed but owner be "aware."
