Sony TA N77ES sells for 1K and more. Is it worth it?

I noticed that Sony TA N77ES still changing hands on ebay. It costs from $850 to over $1K, depending on condition. I wonder is it some kind of a cult thing - yes, it looks good, - or it has really outstanding sound (for the money)? Is it comparable to smth on a current HiFi market?
I am currently using one.  It was my father's which he owned from when it was new.  My two most recent amps before it were a Pass XA-30.8 and PL HP integrated.  I don't plan on getting rid of it any time soon.
Thanx! What preamp and speakers do you have?
TA-E80ES and Harbeth SHL5+
Got it. Pass is quite an expansive amp with great reputation, so it looks like it makes sense to give 77 a try if it's in good (restored) condition. Thanx.
