Mark Levinson 27.5 versus modern day amps

I had started a thread on the 334 but looks like the caps if not replaced is a crap shoot. However, how does the 27.5 compare to some modern day or newish amps? Do you think it would be worth it to purchase a 27.5 as they seem to be going for $1800 to $2700.  Upwards of $2200 is ridiculous in my opinion as they used to sell for $1700-$2000 a few years ago. Also what preamps mate well with ML amps?
