McIntosh C28 preamp and MC 2505 power amp landed in my lap

Not a gift. He wants to sell them. But they are in my house to play with. So, they did in fact drop in my lap. I could probably buy them for less than the $1500 he is asking but I really do not need a 3rd HiFi set up. 

Please do not lose the point of my question. 

Depending on many factors they might sound very good as is, or may need repair/refurbish costing more than you are thinking...

I would only have them worked on if I might keep/use them: by McIntosh IF still working on those models, perhaps Audio Classics (down the road from McIntosh in Vestal, NY), however preferring tubes, I would not get involved with them.

Even if you prefer SS, these are not ’fall in love with’ models IMO.

Many years ago I was given a SS C28 and much more powerful SS MC2250, used them for years when I needed more power. 6 years ago, around when I joined audiogon, I went back to my efficient horn speakers and bought vintage tube preamp and amp.

I had trouble with noise on the C28’s low level inputs. Even when fixed, I preferred the little switchable MM phono eq in my AT120tt to the sound of the C28’s phono. I also preferred the $14. Pyle MM Phono to the C28, it was lifeless somehow.

Had McIntosh adjust my C28 and MC2250, got new OEM boxes, easily sold on eBay. Had Audio Classics overhaul my MX110z Tube Tuner/Preamp (a definite fall in love with model) because McIntosh does not work on that model anymore. I highly recommend both companies, neither were greedy, work was prompt, their certification definitely helps sell.

I had the advantage of not needing to/fm shipping, I combined drop off and pickup with visits to my photography friend Bill who lives in Vestal.

I worked at McIntosh dealers when these were current models back in the 1970s.  They were great gear then, especially the 2505.  The C28 was meh. When new the 2505 retailed for $449.00 and the C28 for $499l.00    That is neither here nor there now but interesting trivia.  They are collectable now and as you have discovered quite valuable.  Whether to sell them as is or get them serviced first is strictly economics.  I would take a hard look at them, if they don't look like they have been left out in the rain or otherwise beat up, that is they are cosmetically good, I would be inclined to have them serviced and go for the big bucks.  Otherwise, or if you need the money, then sell them as is for a quick profit.

I have the equipment up and running now. It sounds pretty good for 50 year old HiFi equipment.  There is some crackle in the switches but for the most part I am pleasantly surprised at the sound quality. 

I will list it on Audiogon as is for $2500 for the set. Free shipping in the Continental USA
