Would be interested in hearing about comparison results of current Mac SS vs Vintage restored Mac top of the line SS ..
Most of the negative comments seems fo be about modern Mac Amplifiers with Mac pre amps , I'm not a fan of their SS Pre amps and feel the amps should be listened to with a different unit ..!
I don't like all of their amplifiers, only certain ones. The newer high powered amps are different now than they were back in the 1960's- 1980's.
I grew up listening to the MC275 in the 1960's -70's, my dad's stereo. McIntosh brought back that thing starting about 1995. I had a chance to hear a version of the new incarnations of 275 in 2006. It sounded exactly the same to me as before. Improvements were in the speaker binding posts, probably added Power Guard too.. Obviously printed circuit boards replaced the old point to point wiring from the 60's
The 275 is a excellent basic power tube amp that lacks deep bass. My MC2102 tube amp which I bought in 2006 has all of the attributes that the 275 has plus deep bass. I use my MC2102 for digital playback. Some say using 2 275's in mono mode delivers better sound. I did that demo at the dealership and no change in the sound was noted by me. Others claim the same improvement regarding using 2 2102's in mono. Once again I heard no such improvement. I currently use a Conrad-Johnson line stage tube preamp with my MC2102 tube amp. The CJ preamp will remain with me until the end.
I liked the 4100 receiver from the early 80's too but chose ReVox B780 over that based upon sound quality and it had a better sounding tuner with additional adjustment knobs that could further enhance the sound of the tuner section.
The MAC4100 is still a very excellent receiver however.
The MA6200 was a great integrated amp back in the late 70's -the mid 80's. I now have a MA6500 integrated amp that I use for analog playback.
The C29 preamp was nice as was the C22 tube preamp. McIntosh has brought back the C22 and is a current production preamp.
The other preamps from that era through the present time didn't grab my attention.
I feel that McIntosh 2 channel digital audio components to be better and more musical over other brands.
Other brands that I liked from the early 1980's was Threshold and their Power Stasis amps and preamps. Also Naim Audio. Mark Levinson was great in the 1970's. Conrad Johnson caught my attention in 1980's though the company was started in the mid 70's. Belles was nice in the early 1980's. Tandberg had great amps/preamps in the early 80's also.
McIntosh amps/preamps have a loyal following.
Most of their products dating back to the 1950's can still be fully restored to spec. The exception is digital components which do have a shelf life because replacement lasers and other limited production parts are no longer available.
While at the MAC dealership in 2006 I had the opportunity to hear their Dare To Dream system.
I was not impressed. Mostly because it's too big.
I prefer smaller and simpler setup.
So in summary, McIntosh offers a line of products that will appeal to many. I find some of their amplifiers worthy of purchase but not all of them. Their customer service has been, and still is, excellent. Their products designed to last a lifetime and beyond. It's not at all uncommon to see their products from the 1960's still in use today and still meet or exceed the original specs.
Some their newer amps like the reincarnated MC3500 would be of interest to me if I were shopping for a new amplifier mono block set.
The C22 preamp is also current production which would be something that I would pair with the new MC3500.
Anyway, I'm just one guy with a opinion on McIntosh amps/preamps. Having lived with McIntosh on and off since I was born.
There's always a McIntosh amp that will appeal to me over other brands these days. I have had my MA6500 & MC2102 since 2006 and they will remain with me.
I hope that you find some of this information useful.
Just my opinions.
