Are those folded ribbons the same or similar to those used in Goldenear Aeon speakers?
I have heard those. Much different top end from any soft domes I have heard. Very polite is the term I used to describe the sound. I could easily live with a pair of the Goldenear Aeon speakers in the right room.
I find the OHm Walshes quite easy on the ear and not fatiguing though they can go somewhat that way in some cases. But not nearly as much as my Dynaudio Contour 1.3mkII or Triangle Titus monitors.
I recently acquired BelCanto C5i Digital Class D integrated amp in my second system. None of my speakers have any sign of hotness or edge ever with this amp. Its the first I've owned (and the newest with latest greatest technology) that I could say that about. It would be interesting to hear a good speaker with folded ribbon tweeter on that.
Many factors that contribute to sound.
My very first "good" speakers (Criterion) had Heil air motion transformers. I bought these when working at Lafayette Radio circa 1977. I was a newbie then and liked those over other speaker brands sold with other tweeter types.
Problem was they would always blow out at modest volume even off 40 w/ch lafayette integrated amp I had at the time so I dumped them after about a year (for OHM Ls I heard at tech Hifi).
I'm sure the modern equivalents are much superior. There are many speakers from those days I would bet could sound in another league these days with modern digital and amplifier technologies in play.
