My first piece of real hi-fi equipment was a McIntosh C24 pre-amp. I loved that unit. I paired with a Dynaco 120 amp that I built from a kit. The Dynaco was all I could afford as I spent all my money on C24.

The Dynaco 120 was a really good power amp. I'm impressed you built it from a kit.

The Dynaco was indeed a good amp. I remember when I took it in to one of the McIntosh amp clinics to get it tested and it did quite well. I see you have a Rabco SL-8E. Does it still work? I retired mine yes ago.

MA 6100 Review
MA 6100
Integrated Pre-amp/Amplifier (Solid State) Last suggested retail price: $$699.00 Preamp-Amplifier 70-watts per side at 4 or 8 ohms, 40-watts per side at 16 ohms McIntosh McIntosh builds dull boring, high power, low distortion amplifiers which has been the laboratory-standard for performance since the middle of the last century. Whatever you put in, is what you get out. McIntosh built its reputation on the audible purity of sound reproduction. They probably made amps for the phone company. The equipment is strong enough to be handled by a Bear, and is still in use after 35 years. The MA 6100 has all kinds of inputs and outputs that I did not need back in the seventies, and I sure do not need a bunch of input and output jacks for tape recorders now. You can hook up your DAC to play your high-resolution digital tracks on your hard drive. But in my thousands of days I never needed to hook up two tuners, two phonos and a tape head whatever that was, to get great sound. Two things, listener fatigue, and the McIntosh sound are why I stay. If you are contemplating a move to Mac, search for, maybe memorize McIntosh’s Lost Instruments Brochure from 1952. Mac’s sound does not add anything or subtract anything from the message in the waves. The result is freedom from listening fatigue, full dynamic range at all volumes, and complete music realism. The MA 6100 is a Vintage 70-watt pre/amp-amplifier sold during the seventies. It replaced the 45-watt MA 5100 ($449.00) from 1966 and was itself replaced by the 75-watt MA 6200 ($1,899.00), which went until 1991. The 6200 were pretty much the same except it had an equalizer and anti-clipping added in response to the then new digital sources. I lived with the MA 6100 for over fifteen years, then had a MA 6200 for over ten years. I did not use the equalizer, and I do not need Power Guard to keep from blowing my speakers apart. Now I am back with the MA 6100. Both have Headphone amps and no meters. The 6100 have dual concentric tone controls. They decrease turned to the left, flat straight up, boosted turned to the right. They function, but really they are just decoration and will never wear out from turning. The balance control reduces the signal to the opposite side it is turned, to give equal sound pressure to the listener’s ears. The on/off switch volume control, has an audio taper curve. It is a modified logarithmic curve starting with a dead zone. When you turn the knob, you can hear the volume change with equal movement. I did not know much about the compensation switch except that it made the music sound better and I left it on for over twenty years. It converts the volume control to a loudness compensated control switch. The effect is to give a flat frequency response across changing volume levels by keeping the low and high frequencies volumes up as the main mid-section volume is reduced. The effect increases as the volume is lowered so that we still hear the full-frequency range at lower volume levels and flat response is obtained at full volume. The presence position boosts mid-frequencies. Quote:
For example. If one of your sides is silent you can quickly check if it’s the amp, by running a mono signal to both speakers. If one is out check your speaker wires. If the both work, switch one channel to both sides, you will know in an instant if one side is out. Using the pre-amp/amp jumpers you can find if the source is before or after leaving the pre-amp. These controls just make it easy to set up or trouble shoot. Once you get use to these luxuries it is a pain to go without them. The 6100 were always easy to set up quickly to give great sound whether it was for a few months or over a decade. It has easy to reach switches for two sets of speakers. After about eight years in one location it picked up a hum I don't remember if it was the 6100 or the MA-6200. But it was handled by running from the ground binding post on the back, outside to a copper rod in the yard. The back has outlets up the yin-yang. Once I got the speakers hooked on I never gave any of them any thought at all. The Preamp is really separate from the Amplifier even though they are in the same case connected by solid wire jumpers. The "U" jumpers can easily be replaced with "Y" jumpers to install a subwoofer. These Jumpers are very handy for trouble shooting, or modifying the sound. Some very ill advised reviewers have suggested changing the jumpers for cables. Quote:
Most of the features offered by Mac I do not need. I just need the 6100 to take the digital output from the source, and put it to the speakers without changing the sound at any volume. The true function of an amp is very simple, but we get confused with all the stuff wrapped around it. Newer is not always better, a lot of the escalating costs are for some new invention that you may never need or to solve some problem that you never had. Just like with sports cars, it takes time for newcomers to realize the affordable way in to high end audio, is the pre-owned market. If the goal is to have it sound like it did in the studio, vintage studio quality audio is at least one way to go. What I find audiophile's are doing today is putting together systems so that they can change the original sound as if the stereo is one giant musical instrument, and they are doing the final mix. No two are the same, no-one agrees what it should sound like. Except they all agree that with two ears the surround sound debacle does not lend itself to great audio. It has been dismissed, and the consensus is two channels, or two channels with a subwoofer is an efficient way to great sound. My advise is to get a vintage McIntosh and have it fully serviced, restored, brought back to spec, and keep it until you die. Product Weakness: Shipping and packing costs Product Strengths: The lack of listener fatigue in the McIntosh sound, and the “variable loudness logarithmic volume control.” Associated Equipment for this Review: Amplifier: McIntosh MA-6100 Sources: digital, tape, TV and phono Speakers: JBL-100, JBL-4310, JBL-4311 and others Speaker wire: 14 gauge Music Used: All sounds Room Comments: Many rooms, many houses, many islands and the mainland Length of Audition: Thirty five years Type of Audition: Product Owner |

Enjoyed it too. Hard to go wrong with well-loved, pre-owned McIntosh.

First time post for me here. I've been an audio nut for 40 years and have owned all makes and models of gear over the last four decades. A few years ago I bought a restored Fisher 500C and have been using it in my main system and a X-100-C in my bedroom system. Love the Fisher tube sound. Recently I decided I wanted to add McIntosh solid state gear to my main system. I bought a beautiful restored MC2105 amp from a dealer in Portland and a C29 preamp from Tom Manley. The C29 will be here in a few weeks. I was anxious to see how the amp sounded so I'm using a Yamaha CR-1020 for a preamp and I am just blown away by the sound of the McIntosh. I can't wait for the C29 to arrive.
