Selling a Macintosh Amplier MC-352


My audiophile husband died last year. Now the audio system he lovingly crafted and tweaked over a number of years is in the hands of a terrible mother who has no idea what to do with it. He'd be horrified, but I just want something simple to use that I can control via my computer. He was an enthusiastic user of Audiogon, so I'm coming to those of you in "The Club" with the hope that you can help me figure out what to keep and what to pass along to someone who will appreciate it better than I can.

My first question is about the amp and preamp. The amp is a Macintosh MC-352. The preamp is a Macintosh C2200 Tube Preamp. (He also has a Macintosh MCD 205 compact disk changer, but my question is really about the amps.)  Sonos tells me that I can plug my turntable WITH a preamp into the Sonos device. (The CAPS are mine, for emphasis.) What I don't understand is whether this means I can use the preamp I have, or if I have to have a turntable that has a built-in preamp (not even sure if there is such a thing). Do I need to keep my preamp?

The second question is about the amp MC-352. I notice that there are none for sale on Audiogone. I don't know if that's because there's no real market for them, or if it's simply rare to see them for sale. I do find a price in the Bluebook for them.  So, is there a market for the MC-352?

Can any of you help?

Mcintosh probably have close to the best resale value of anything in used audio. Reliable and desirable. Kind of the Rolex of high end audio. 
this amp will be sold at very good $ even out of new ebay account when you start from buck.
you will sell it real GOOD.
My condolences regarding your husband.
I hope you will find the answers you seek.

Hi Elise,
These are much easier to sell if you have the boxes.  It's scary to pack these up and sell them.  Like the folks above said, don't get lowballed.  This is really nice gear.  Manuals, remote controls and boxes all add value.
1-I don't think you will want to bother using any of this through your Sonos.  They are big and cumbersome-which Sonos is not.  If you want a turntable hooked into the Sonos, it should work.  You can use any turntable and you will need a phono preamp.  This is a box that will convert the sound properly.  You can get them from anywhere from $50 to $5000.  Keep things in perspective.  Walmart has a Music Hall for $75 that will work fine.
2-Selling the gear.  You can list it on Audiogon and say "local sale only" if you are scared of shipping.  Or, you could sell it through a dealer.  I agree that Audioclassics.com is great.  Since you are from Chicago, Saturday Audio is another great store that you may have come across.  USAudiomart.com is good too.
3-Craigslist is awful-stay away.
4-Ebay can be scary unless you are experienced there.
The biggest single obstacle to selling Mac power amps is the potential shipping damage even if the amp is boxed properly using Mac deigned shipping boxes, the problem is the sheer weight/mass of these little monsters and also the very fragile glass faceplates, I have seen too many shattered faceplates curtesy UPS/FedEx rough handling of these amps..
If it were me I would advertise it as local pick up only, who knows you may be lucky and find someone within reasonable driving distance
