My guess it's like a 60's muscle car. It was fun then and it's fun now. And and VW GTI will outperform it in comfort in many ways (not all).
A month ago for the fun of I hooked up an old Adcom amp to my system - it was my friends and he had it for a while and in college it was my idea of audio bliss.
I hooked it up to my preamp and my speakers...it sound horrible. It lacked the dynamics of my Moon amps - sound stage was smaller, bass was undefined and it was an experiment that lasted for 15 minutes. And in college that amp with Boston Acoustics speakers was something I could and did listen to for hours.
