Preamplifier - McIntosh C32

Why do I collect McIntosh gear? Because every piece I acquire instantly becomes my new favorite - out of all brands.

This C32? My new favorite preamp. Followed closely by my McIntosh C31V. Now granted, I haven't listened to hundreds of preamps. I'll go as far as to say that I'm certain, especially considering advancements in technology, there ARE better preamps out there. Will I ever own one? Dunno. I'm still young and delusional enough to envision a day where vast wealth will provide me opportunities to spend $10,000 or more on a preamplifier. In the meantime though, I'll stick with what, in my mind, is the most beautiful, clean-sounding, full-featured preamplifier I've experienced. That is until I save up enough for a C39 or C40 :)

Want the specs? Let's let Roger Russell provide those.

By the way, if you'd like a higher-res version of the above photo, shoot me an email and I'll hook you up. Let me know the resolution and size.

Have any experiences with your C32 or other McIntosh preamp you'd like to share? Please leave a comment or shoot me an email. hificollector [at] gmail.com

Power Amplifier and Preamplifier - McIntosh MC7270 and C31V



First off, I apologize for the stock photos, but mine look exactly like that - I swear! I'll replace these soon with a shot of the whole system after the tuner arrives next week.

This is a preliminary assessment of this 7270 power amplifier and the C31V preamplifier, as I've only listened to these for about two hours so far. I'm using the 7270 in place of my MC2100 which has served me well for about a year, powering my KEF 105.2. The other components in the lineup, the preamp, tuner, and CD player have been switched out several times over the last 12 months as I opted for more inputs, better CD sound, etc. (you know the drill). I am currently using a Conrad Johnson Sonographe CD player with these McIntosh components and it sounds fine.

Let me address the differences in sound between the MC2100 amp/Adcom GTP350 preamp combo that these new McIntosh units are replacing. There is very little "noticeable" difference. No, my hearing is fine - actually quite a bit above normal for my age according to my doctor. What's missing here? Why aren't I extolling the blatant superiority of the sound coming from this new gear over the old system? Because they both sound REALLY nice to me! And, the only way I'd be able to tell the difference between these two is if they had significantly different sonic characteristics, and quite frankly, those don't exist. Set up a blind listening test where you can instantly switch out the two sets of gear, and I could write volumes about the differences I hear. But - add setup time of 25 minutes between listening to the two systems, and my sonic memory fails me.

So, enough with comparing these two - how does the new McIntosh gear sound?!? It sounds wonderfully natural. The phono stage on the C31V has allowed me to rediscover vinyl, and I had a blast last Sunday morning listening to some of my favorite LPs, including "Herb Alpert and the Tijuana Brass - Whipped Cream and Other Favorites," and "Stan Getz - Getz/Gilbarto." Both of these were uncolored, very neutral. The percussion and horns of the Herb Alpert sounded spectacular - "live" but not forward. I was IN the studio with his band.

And hey, what's not to like about the looks of this gear? The C31V does not have a full glass face - only partial, with brushed aluminum along the bottom, but that's okay - it still has that futuristic retro-chic like it belongs on the set of Sin City. The Amp. . .masculine but pretty at the same time. Those huge, glowing watt/db meters. . .drool. Both of these units came to me by way of a Craigs List ad, and the seller may have more to unload some day. I'm keeping my fingers crossed! He kept these in immaculate condition, and we worked out a fair price which is always nice.

Still to come? For my second McIntosh system, I should have a McIntosh MX113 preamp/tuner on my doorstep when I get home this evening. This will go with the MC2100 amp. Then, next Wednesday, to replace the Pioneer tuner being used on the system described above, I've got an McIntosh MR7083 on its way. Yes, when I dive into something I go whole-hog. Speaking of hogs, I think it's time to replenish the old piggy bank!

Full system review coming soon after I get the new tuner installed.

Preamplifier - Philips AH 572



Phillips 572 Preamplifier - Okay, this thing is a trip! I love interesting component design, and brother, this one takes the cake! Not particularly industrial, not overly futuristic, heck! I can’t even tell you if it’s good-looking or the ugliest piece of gear I’ve ever owned! All I know is that it would look equally at home in Dudley Moore’s swinging bachelor pad from “Foul Play,” or sitting on the bridge of the Star Ship Enterprise. The controls are touch-sensitive and have LED activation feedback. There are 16 light bulbs that illuminate the function buttons. I stumbled across an insane restoration of this piece by someone who really knows his electronics. I read through the restoration and felt compelled to leave a comment on his guest book. You may want to do the same if you’re left as dumbfounded as I was by the detail of his overhaul.

How does it sound? Very nice! Well-balanced, buzz on the left channel, great tonal control. The volume goes from 0-60 in two clicks, but if you have a power amplifier with adjustable gain (output), then you can tweak the control from there. Did you catch that second comment? Yeah, it has a low-level buzz - [note the easy lead-in, and uncharacteristic restraint demonstrated by not making a drinking joke here] the kind of buzz that's easily covered by music, but the mere existence of which drives you nuts. Oh well, perhaps the guy who did the rebuild would be interested in another. . .probably not.

Preamplifier - dynaco PAT-5



I don't have a lot of "separates" in my collection, but I do have a couple dynaco (yes, the trademarked name has a lower case "d") preamps including this PAT-5 from 1974. I love how you can open up these cases and see the pristine, clean interiors. Since these cabinets are sealed, the insides should look factory-fresh, which is always a nice change from most of the filthy units I have to clean out (one of the joys of collecting). Under the hood, take a gander at the wiring and soldering on these, which were done with skill and great care. I don't have much info on dynaco, but here's a page with plenty of info on dynaco.

How does it sound? This particular unit needed some contact cleaner for the volume, but besides that, it sounded great. Had it hooked up to an Adcom GFA amplifier for a while and it sounded just fine. Sorry - it was over a year ago, so no details on the exact subtleties of sound quality.

If you have any photos or stories about your dynaco PAT-5 preamp, please leave a comment or email me.

Preamplifier - Phase Linear 4000


These units needed help. Tuns out, a previous owner has Frankensteined parts from other units into both the PL4000 and its companion PL400 power amplifier. The new owner of these, a collector of vintage Phase Linear equipment, is fixing them now. Bob Carver founded Phase Linear in 1970. You can read the full Phase Linear story HERE.

If you have any pictures, stories, or video clips of your Phase Linear 4000 or Phase Linear 400 units, please leave me a comment or send me an email.

Preamplifier - hh Scott 121-C





This is a fine example of an hh Scott 121-C tube amplifier from 1956 or 1957. I don't collect tube units - yet, but this came to me through a friend, and I couldn't pass it up. It is in near-mint condition and looks like it's been kept in a sealed, air-tight storage box for 50 years.

Immaculate physical condition, in this case, didn't translate to immaculate electrical condition. This unit hummed and had low-level volume, but needed new tubes or new caps.

If you have any more information on a Scott 121-C, including photos or personal stories, please leave a comment or email me.
