Celestion SL6S

I haven’t tried other cables; however, I would say my cables are fairly neutral.  My USB cable from the MacBook to the DAC is an audioquest coffee.  The interconnect, power cables, and speaker cables are DIY Helix Image.  I would say they are extremely neutral with great imaging and texture that allows for great soundstage separation.

Also, other speakers don’t roll off like these in the same system.  Could some of the old crossover parts be shot?  Could the tweeters be tired even though they are playing?

I couldn't commit to buying the SL600s due their lean tonal balance, but boy the imaging!  I still remember listening to Peter Gabriel's "So" LP at a dealer, and it was spooky good!

I remember hearing the SL6s back in the early 80s. The distributor loaned the dealer a pair. I almost bought them on the spot! Thought they were excellent speakers.

@kb54 well, I can tell you that I had one of those spooky experiences over the weekend.  The highs are still rolled off, more than I remember, when I owned them years ago.

All I know is that the soundstaging, midrange, and even the bass (it wasn’t deep of course) was something else…
