Mac vs the Japanese

My 1980 Sansui liquid cooled AU-D11.

onepixel....cool looking liquid-cooled amp...never knew they made one like this. I heard of computers with them but amps? wow..... way ahead of their time ?
 
"That additional set of requirements limits the field. I'm not sure what, if any Mc preamps had MC inputs. As for power amps greater than 200 watts and into 2 ohms also limits the Mc power amps by knocking out the likes of the 250, 2505, 2100 and 2105. You've also knocked out all the vintage tube units save the MC3500 mono power amp. Also, think you've knocked out the 2300, 2500 and 2600 power amps. It is not that the Mc may not be stable down at 2 ohms but most of the autoformers are 16, 8 and 4 ohm wound. The newer units have 2 ohm outputs."

See Below:

MC2150: Output impedance 1, 2, 4 and 8

MC2155: Output impedance 1, 2, 4 and 8

MC2200: Output impedance 1, 2, 4, and 8 ohms

MC2205: Output impedance 1, 2, 4 and 8 ohms

MC2250: Output impedance 1, 2, 4, and 8 ohms

MC2255: Output impedance 1, 2, 4 and 8

MC2300: Output impedance 0.5, 1, 2, 4, 8 and 16 ohms

MC2500: Output impedance 1, 2, 4, and 8 ohms

MC2600: Output impedance 1, 2, 4, and 8 ohms
 
Wakey Wakey..... what everyone went to sleep...?

Can some one provide a URL that has info on what units are considered the Vintage SS Mac's to read up on...

thanks,

Here are the 2 best McIntosh sites on the internet IMO, TONS of info, specs, and even manuals.

That said, being a Jersey-boy, you're not too aweful far from the McIntosh Mecca right here in Vestal. If you ever get in the central NY area, take a ride to Audio Classics to see and hear all of the new and vintage Mac in person. Its really quite the store, having it as my goto audo supplier, I sometimes forget how spoiled us locals are; Accoustic Images right down the street is worth a walk through as well, although not even in the same league.

I went to the real Mecca.... Saul Marantz's home on LI...... :)

Thanks for the URLs... good idea on the NY visit.....I have to see how to work that into the schedule...

Gee, after seing all those nudies, I really appreciate the simplicity of say a Marantz 7C and Dynaco ST70 or a pair of Grommes Little Jewels.

I did not know you were into them Grommes.
Or the simplicity of a Radio Craftsmen 500A. BTW Onepixel Sansui is really "cool".
 
Brian, you said it in diplomatic fashion. I would have stated "Accuphase owners often hold the belief that Accuphase is on par with, if not better than, McIntosh." The same can easily go for Esotec, and there are numerous examples of all Japenese manufacturers reaching the same pinnacle or higher. I would be hard pressed to find a Mac crossover unit like the Pioneer D23 Spec series.

I still have a MA6100, 1900, C104, MC2100, and MR67, so I am not unaware of either the history or the years of excellance of Mac. I have witnessed examples of the bow and scrape here, and I am also awaiting to read what vintage equipment from Mac is considered their best.
 
I was using a fairly new Carver receiver, far from hi end but not junk. Then I thought, why not try a used Mac, so I bought a Mac MA230 integrated hybrid amp, SS pre with all tube amp section. After hooking it up I was instantly blown away at it's sound quality and build quality. I was hooked on Mac. I've since bought and restored a tube MX110 tuner/pre and it is my best sounding piece of gear. I also use a Mac MR67 tuner. I am not however attached only to Mac. I use various pieces of vintage tube gear including Fisher and Scott as well as a Pioneer SX828 solid state receiver.

That MC3500 is a real beauty.....I would love to recap that beast. Looks like Sprauges..and the layout with the transformers and tubes. That 350 watts is probably conservative....just thinking probably 500-700.....maybe there is a Mac amp in my future.
 
Brian, you said it in diplomatic fashion. I would have stated "Accuphase owners often hold the belief that Accuphase is on par with, if not better than, McIntosh.

not a belief
 
Folks:

I just noticed that the original post was for "solid state" components so please forgive my last post on the MC3500 which is "off topic". Perhaps it should be deleted.
 
I like to think that what one prefers as audio bliss is personal. Having
said that, Mcintosh has on numerous times really sounded good. I found
myself constantly thinking about if the sound was worth the money and hype.
When I stopped mentally comparing and just started listening, I was moved
by the solidness of the bass and smooth midrange. This was equipment from
the seventies i.e. MC-2205, Mac 1900 receiver, MA-6200, MA-6100, C-28
C-32. Marantz, Luxman, Pioneer, Sony were brands that I visited often. But
then I heard Yamaha. The B-2 and B-1 to be exact. This was seventies gear
also. It seemed like Art Garfunkel opened the door and introduced himself only
after the Mcintosh gear was replaced by the big v-fets. No, they are not
the ordinary trannies, but Mcintosh could have used them in their R & D too,
so fair being fair the Japanese Yamaha amps were in fact more
transparent and won in every respect. I hope all AK'ers can find musical
bliss as well. :D

In the mid seventies, fresh out of the oilfield, a pocketful of money and a poor Pontiac Grand Prix Model J I set out to audition my dream system. I live in Wyoming but also triede the neighboring states, Montana and Colorado.
I owned at the time a Magnavox TT/ Receiver Combo with some matching Magnavox Speaker cabinets with a 15" woof and a 12" horn. My first visit to a high end store and I was in awe, Crown, McIntosh, Kenwood, Pioneer, Sansui, Phase Linear, SAE, Sheesh what a selection.
I really had no idea what I wanted, save a reliable , good sounding system that wasn't going to be obsolete in a year or two. Stereo salesman at the time were not inclined to leave a 20 year old oilfield winch truck driver alone in their listening room and I probably did not audition a lot of gear the way I would have liked. But there was one store in Billings, Mt that let me have free run of the place for two hours to try any source, pre or amp they had. My hearing was never the same, not as you think.
My ears were exposed for the first time to QUALITY sound. Another conclusion I came to was the SYNERGY of certain combinations of equipment. A Spec 2 DID not light up a set of Ohm F's the way the Crown Inter. Distininction Series DL2 did. Loved the pure clean F's though. Loved the Spec 2 also.
At that time in my life simplicity of pack and move was a consideration. We oilfield types in those days were a bunch of gypsies, moved A LOT. The ear could tell the Spec 2 was having trouble with the Ohm's, IT WAS NOT having trouble with the K-horns, a Mac was having problems with the Ohm's also and for the life of me I cant remember the model number, but smoked some big JBL's.
Wound up buying a Spec system with some Bose 901's and keeping the Magnavox speakers for the thumping bass the 901's lacked, always wondered how the
Mac would have stood up after 33 years and 16 moves. From this thread i would guess pretty well.
And after all my rambling I guess my point is that the synergy factor is what stayed in my mind. Later I owned a set of Ohm F's driven by a PhaseLinear 700 off the Spec 1, with a set of Kornerhorns driven by the Spec 2, anyone want to guess what that sounded like?
Great thread, great input, The best of AK!

Nice story. You chose well getting the Pioneer Spec gear.
