I had a chance to audition Aesthetix IO Eclipse and Nagra PL-P in my system.
They are not ss, but the only ones I had a chance to get.
I was impressed with Nagra. The only problem was bass control.
Aesthetix's bass was perfect, but with the rest it was less natural.
I also hope to try MBL 6010 and Tidal Preos.
I'm very interested now in Sovereign and Klyne.
They are much cheaper, so do they really in the class cost no object?
