We should have some KGSSHV's up and running in a few months (I'm going to build a few) so a TOTL SS amp would be available for testing then. Still the KGSSHV is more of an effort to approach the Blue Hawaii in performance but not having tubes to worry about (and people debating different ones) does have its advantages.
I'm going to send you something to test Tyll but it will have to wait until I first receive and have time to completely refurb then. First off would be my utterly mint and SR-1 set (circa 1962-4) to show just how good first generation Stax was. I also have a SR-X Mk1 incoming which was the first set Stax made for the Pro market. One of only two Stax sets I've never tried (the other being the impossible to find SR-2) so I'm really looking forward to testing it out. Now with these vintage sets you need a normal bias amp with not too much output voltage as they will arc violently when fed too much juice (ditto for the HE90) so I have a 1969 SRA-3S preamp incoming which is perfect for this. One of the best amps Stax ever made (just ask Kevin, he had one back in the day) which I'll completely rebuild to not fall into the same trap as Hi-Fi News when testing vintage gear.
It would certainly be a shame is something like that were to occur...
