Bottom Line:   
For years I have tried to get my hands on one of these for cheap. I would read stories on message boards of people buying McIntosh gear at estate sales for $20 a pop, or finding them on the side of the road in perfect condition. About a month ago I found a MC2105 that was "immaculate, stored for 30 years." I bought it for a song and brought it to a technician to have a look at it. Cosmetically, yes, it was immaculate, but it did have some electronic issues.

I called McIntosh directly and they were super friendly on the phone, all the parts I needed were in stock and not terribly expensive. About a week later my tech had completed a full restoration of my amp, everything from the output transistors to the capacitors. When I brought it home, I mated it with my JBL 4312a Control Monitors, new old stock PS Audio 4.6 Preamplifier, and modified Technics 1200 MK2. I was floored. I've heard plenty of McIntosh gear over the years, but there's something different about hearing it in your own home.

Like others have said, it is a very musical amplifier, I think that is what I like about it most, it is very pleasant. The official specs say that the damping factor at 8 ohms is 10 and 18 at 4. That would lead some to believe that the bass is not tight or refined, however, I find the bass on my 2105 to be very good. I would describe it as stately, not boomy or muddy. The autoformers ensure clean and distortionless power delivery at 4,8 or 16 ohms without clipping. I can listen to this amplifier for hours, at almost any volume, without fatigue.

Before I had the 2105, I had a Pioneer SX-980, a Sony STR-7065 and a pair of SAE Mark 2500 amplifiers. In comparison I found the Pioneer to be too bright and a little dry, the Sony to be pleasant but lacking enough power for my needs, and the SAE amplifiers to be too much power with poor reliability. All of the pieces of gear I owned before this, while good in their own right, did not suit my needs and tastes the same way the 2105 does.

For me, the years of waiting paid off, and I am thankful that I was able to get this amplifier and a full restoration for less than the price of an unrestored example on ebay or audiogon. I encourage anyone who has an interest in this amplifier, or McIntosh gear in general, to give it a shot. Even if you hate it (which I doubt you will) you can ALWAYS sell it and make your money back. As for me, I will never sell this amplifier, never. I'm selling off all of my other gear only because I don't see myself listening to it now that my McIntosh is in the house.

Bottom Line:   
Well what can is say, its a very strange amp! Not only because of the retro looks (It's from like 1969) Ik love the looks after a few days of adjusting to it offcourse.

The sound is tricky, we tested it with Infinity QE speakers. Did not work, harsh sounding no control at the high regions. And no low frequenty respons. With The Driade 103mkII (Topmodel of that brand a true legend) The same thing happend. LOTS of detail in the high and mid range. Yet again no low frequenty respons. Reallt annoying fact!!

Seen the fact i own a Dynaco st80 tube amp, And a audiolab m480 amp. Put them on those speakers and the ROCK ! With the MC2105 nothing ! Then gentlemen i had my last hope. The gigant Magnepan MG1 out of the 70'. Modified with supertweeters. Iff this is'nt gonna work then i trow away the MCintosh for sure.

We did it put the Mcintosh c26 pre-amp and the Mcintosh mc2105 onto the magnepans. As source we used a dual 503-1 turntable and a modified Sony xa50es cdplayer. Till our suprise ! THE ROCKED!!

FINALLY !! IT WORKS! i was so thrilled at that moment. Because you buy something and it does'nt work with the easy speakers. But with de magnepan the amp suddenly whas alive and kicking. What a dynamics and very good solid low region all of a sudden. We used Direct master vinyl of Norah jones,sara k,diana Krall..and stuff. Really nice the best sound i have right now ! And believe me folks, i had ALOT OF STUFF before is bought my mcintosh.

Now i'm very happy with my mcintosh set-up just bought meself a Mc1900 receiver that i want to use a tuner. It does'nt fit nicely with the c26 and mc2105..but who cares it works like a charm.

We people, most of us think that GOD will come from the sky while we are forgetting that HE is here within us in our every day life and steps. We just have to search and identify HIM.
I spent the last 20 years accumulating audio gears of all sorts and prices. Vintage to modern and just realise that what I have been running after is just there and it is just a matter of identifying him. Yes “him” because the MC2105 amplifier sounds just like the sweet voice of your most desired woman inviting you for the first time in her bed covered with silk bed sheet.
A very experienced electronic engineer told me one day that audio gears of nowadays are just build to attract mainly by appearance, than the sweat, love and passion most audio designer put in the project of elaborating decent and close to natural sounding audio gears over the first half of the 20th century.
Well I agree with him in the common sense that I have spent over a year income on audio gears and surprisingly delighted by some even never reviewed because they were ignored, or because they are not from High street famous names.

Have a Baldwin type AD organ quad 6L6 vintage tone cabinet amplifier driven by a decent preamp and compare its sound reproduction with an aluminium face plated 3 figure worth modern amplifier and post your listening feelings.

It’s until 8 weeks ago, I got a call from(now) a good friend in Canada. H e desperately wanted my HH SCOOT Stereomaster 380 unsold on Ebay and offered me a trade deal. A McIntosh MC2105 and MX113 preamp serviced to new. I will pass the details of our arrangement.

Six weeks later, I went to collect them at Heathrow cargo (UK). US$600 shipping plus £120 duty charge. It’s becoming too expensive.

I am a passionate of speakers and have a collection of 26 pairs form Rogers LS3/5a to TDL Reference Monitors and KEF reference 107.

It took me few minutes to connect the MC2105 to the LS3/5a and my faithful Micromega Stage 2 and started with classical records on a Thorens TD 124 II and Hadcock GE 242 Tonearm and Ortofon cartridge.

The best existing bookshelf speaker or monitor can never reproduce a better low frequency spectrum than a lower quality cabinet with a 12 “ bass driver.
But there I come back to my assumption of the beginning : We spend our life looking for GOD in the sky with HE is within us. I have spent a fortune over twenty years while the MC2105 was just there it’s just a matter of pocket.
Then my poor children have to suffer to help me bring heavy KEF 107 and TDL reference monitor and other brand speakers from the loft.
MC2105 is the one of , if not the best sounding solid state amplifier I ever listen.
I AM JUST WONDERING WHAT CAME ACROSS MCINTOSH INGINEER’S MIND WHEN THE ARE DESIGNING SUCH INCREDIBLE, Powerful, Sexy sounding ,Attractive and mostly the final marathon stop for who knows what it sounds like.
The beginning of the answer to this question is What came to GOD’s mind when HE took HIS pencil and stated drawing that most desired woman and her voice inviting you to the silk bed?

I am grateful to McIntosh Labs

If you come across any, even over $1200, buy it. Who will regret it ?

McIntosh MC2105 or a McIntosh MA6200?

What to do, what to do? I have a chance to pickup a McIntosh MA 6200 or a McIntosh MC 2105 & a McIntosh preamp possible a C28. They will come out to be close to the same price. Musically I listen to Classical, Folk, Blues, Rock, and Jazz. My speakers are ESS Heil AMT 10-B. What do you recommend?Read More »
