..........Rob if I may - as I'm wondering about the comparison with the 800's. ........
Well there really isn’t one, while tonally there may be similarities to a house sound, comparisons with the 800 end there. Again it’s early days and while I did have the 660S three years ago, these new ones going from memory (a dangerous thing)appear warmer, the real comparisons come down to the HD58X.
Needless to say the 800/S are like stepping into a luxuries restaurant, where an aura of sophistication and detail become very evident, the space opens up but still layers of richness. The HD660S and HD58X are a smaller venue, more intimate and while the 660 are slightly more polished with a higher selection on tap and better wines, the 58X is still a nice place to visit, affordable, maybe with a few slip ups but forgivable.
Sorry for the restaurant analogies, must be the lock down and imposed restrictions, but I’ll go into more detail later.
Just to add...sounds I was listening to.
