MC 2255 - sweet.
I bought mine new in 1984 for $2995. Got C-33 new at the same time. I have played it nearly every day since then because I play my TV system through it too. The big meters are still dancing.
Had a McIntosh service guy go through it last year.
Tremendous value. Haven't checked resale value. I know the Audio Classics site lists it as "Wanted".
