I think that the only difference between the 108 v1 and the v2 was the SMTP circuit and some hardware, I have owned both.
As far as I can remember the only known differences between the topology of the 108 and the 458 were the number of transistors in the output stage - one pair in the 108, more than one pair in the 458 and the true balanced input of the 458. Does the 468 have a single pair of output transistors?
Please note I am addressing technical details, not sound quality.
Hey guys, yes just got back from my Swiss tour and did stop by Geneva to visit Hervé, we did the factory tour, saw 4 pairs of 468s being assembled and an 108 model 1 being upgraded to model 2
In the aftenoon we went to his place to listen to the rig he has in place at the moment with the 18NS, 108 model 2 and the 208 for streaming purpose.
The speakers he is driving at the moment are the https://www.klipsch.com/products/klipschorn-floorstanding-speaker
no really to my taste, would have preferred the Evolution Acoustics MMthree that he has.
The sound was huge just like a live performance, very transparent, fast and a little tubey.
Unfortunately i have found the treble kind of bright and aggressive, i don't know if that came from the speakers or the amp.
Anyway i have to thank Hervé for taking the time to show me his factory and audition his rig with the new 108 model 2.
