eantala,
I recently bought their top of the line preamp Sonata Allegro and their former top of the line mono amps the Antilon, acutely at the time have had not heard of them before, but a fellow Audiogoner pointed me toward them, so I started doing some reading and I fell in love with not only the equipment but in their concept. They like to do things right the first time. As such they dont have upgrades, as they believe that the product should be done right before it is out in the market. I end up buying the above from a guy in Indonesia. The minute you lay your eyes on the gear you can tell right away that youre looking at some serious gear. Ant it is. When I hooked them up to my dCS (Verdi, Purcell, Delius), I heard lot of details that Ive never heard before. It is great gear. In particular I like the auto biasing feature that one gets when the preamp is matched with their amps. This allows the preamp to change the bias of the amp (50%, 75%, 100%) based on the volume. In any case I am so happy that I dont think about upgrades any more. My vote goes for them, I used to the Mark Levinson Ref 32 and I sold it when I got the Gryohon gear.
