The McIntosh C36, C38 and C40 have the same audio and phono stages and specifications. Feature wise the C36 is a non remote version of the C38 preamp and has 8 inputs. The C38 adds remote control and the C40 adds a five band equalizer and a 20 watt monitor amp among other features. All of these preamps leverage modern, sealed, electromagnetic logic controlled switching. The styling is consistent with current models with the exception of narrower endcaps. My sonic observations apply to the C36, C38 and C40. The specs are identical as are the audio circuits. My comments are based on the C36 preamp (there is no opportunity on Audio Review to select the C36) The preamp is extremely quiet and sonically very clean delivering good detail with no brittleness. The bass reproduction is tight and punchy. Switching is silent and the bass and treble trim controls are quite useful and moderate in equalization. The variable loudness control is useful for low listening levels. The MM phono stage is very quiet and neutral. As I have a large array of inputs I find the C36 very helpful as it includes inputs for phono, 2 cds, a tuner, 3 tape loops and video.

No remote control but I need the exercise. This preamp is a bit more sensitive than my other preamps to noise from my iPhone when it is receiving and sending data. If the phone is 3 feet or a meter away the noise from the phone is not audible.

Ive owned my Mcintosh C-38 since 1996 & cannot find a preamp to best it,ive owned multiple MX models,the C-42 ,C-45 & C-50 in solid state,the C-20 ,C-22,C-2200 ,C-2300 & C-2500 in Mac tube preamps,ive also compared it against my loved Panor/Dynaco tube preamps and the only preamp that beats my C-38 is my brand new C-2600 tube preamp,the Bass & Treble circuits are + or - 12 db that are excellence in their implementation,the addition of the Mcintosh Loudness control circuit is much of what makes this such a special preamp,incorporating different amounts of the loudness contour at all listening levels adds a spaciousness and depth no other preamp has,not even my brand new C-2600,ive ran it with dual Mc-300 amps in mono with XRT-22 line arrays with amps ranging from a single Mc-252 up to my Mc-1201 mono blocks & the C-38 always makes me excited for the next song ,im retired & in my 70s where money isnt an issue,i keep my C-38 because when i buy a new preamp every 2 or 3 years the C-38 always sounds just as good or better,if you are lucky enough to find one with a remote control that isnt broken you buy that preamp before someone in the know grabs it .

The C-38 has 12 volt trigger but it would benifit from having a secomd 12 volt trigger out for very large systems like mine,aside from just one 12 V trigger i see no room for improvement.

Build quality. Sound. Perfect match-up for a McIntosh MC-300 amp

Glass front can be easily cracked, and costly to repair.

The sound of this pre-amp is very good. I don't know what could have been going on with the other reviewer's system to cause him to 'dis' this amp. (Perhaps his speakers were out of phase or something) Coupled with the McIntosh MC-300 amplifier, this is a wonderful warm sound. I'll let you read the other reviews for the details on it. Just wanted to say you won't be disappointed.

For this money-everything,can''t complain.

Nothing.

Completely disagree with previous owner.Extremely good preamp,quiet,airy,huge soundstage,balanced outputs,nice remote,enough inputs,looks cool.Probably Glenn bought unperfect unit-what you can expect from Audio Classics market site.Best way to fix it-send to Mcintosh.I bought my unit new,can''t complain about sound or noise.Plus,I put 3-proung power line receptacle,connect separate ground wire inside,and connect audiophile grade power cord-huge sound improvement.My gear:Legacy sigIII speakers,MC-352 power amp,STEALTH Premier speaker cables, Stealth all silver iterconnects,Stealth power cords,PS audio ultimate outlet.

Has everything feature-wise, plus a warm sound.

Sound may not be "airy" enough for some. Also, no longer in production. Must be carefully matched to amp.

It's unfortunate that this pre-amp is no longer in production. It's a very good pre which had a positive impact on the sound of my system.

Let's hit one of the weaknesses first; if the gain in your power amp is too high, this pre can sound somewhat shrill. I found it best matched with a McIntosh power amp (but of course).

I bought it as discontinued stock at a local hi-fi store. There were two left, I liked it, I grabbed it. Besides the sound, there were a few other factors. First, it has separate listen/record selectors. If you like to make tapes of one source while you're listening to another, this is a great feature. Also, it has a headphone jack built in; the C-38 is one of the few very high quality preamps I've seen to have this feature. Lastly, but _very_ importantly, it has a phono stage (MM only). It's a very very good phono stage on top of it. I was using a Rotel phono stage, which is pretty good, but this was quite a bit better.

The last factor that made me buy this was the apparent longevity of McIntosh components. Most of the McIntosh stuff I see for sale is 10 to 15 years old. I won't mind if this preamp is still around in 15 years.

I should say something about the sound. The preamp I replaced was a Rotel (the model right under their top-of-the-line model). Compared to the Rotel, the McIntosh has a warm, rich sound. I'm very fond of this sound, but some people consider it "veiled" or "not having enough air". It's also been reviled by some audiophiles for having tone controls (they can be cut out of the circuit) and a loudness control (also defeatable). The loudness control is good for quiet listening, though; it boosts the mids and highs as much as it does the bass.

So this is definitely not a preamp for everyone. However, for a high quality preamp that doesn't skimp on features, it's one of the best I've heard. So...five stars from me overall, but four stars for value, since this pre is pretty expensive. (You can find one between $1400 and $1800 currently; sold for $2500 originally).

Great to look at. Regardless of the what some "purists" may say, having tone controls is a nice feacture. Also, the remote was simple to use and very flexible. And McIntosh knows how to package their equipment for shipment.

Poor sound. Also, the relays and/or transformers in two different units I had hummed. But the real problem was the poor sound. I thought the unit was good to start with, but as time went on and the unit got some hours on it I found it to sound slow. And the built-in phono stage is even worse. And I could never get my Threshold FET ten/pc phono stage to work correctly through the various inputs on the C-38. Always sounded strange. Think there must have been some impendance mismatch. Enough so that I after almost a year of trying I sold it and got a Bryston BP-25. The Bryston is a wonderfully clean, crisp and very fast preamp. Clearly superior to the C-38.

Not a very good preamp. Especially for the money. I could forgive the humming relays/transformer, but not the poor sound. You can find many better sounding (cleaner and faster) preamps for the money. Especially the poor sounding phono stage. But none have the magical look of the McIntosh. Too bad it doesn't sound anywhere as good as it looks.

Balanced, dimensional sound, great control flexibility

The treble is a bit strained at high listening levels

This unit has the dimensional sound I always associated with tube preamps. It's natural, a bit smooth and warm, and nicely balanced. Also, it has incredible control flexibility and convenience. I've had tube preamps for over 10 years and I'm amazed that this ss unit hold up so competitively with tubed units. As an added benefit, MAC gear seems to hold its value very well on the used market. I picked up this 3 year old unit in mint cond (box, manual, remote) for $1200 (retail $2500). I feel I got a reasonable deal.
