Hi Baranyi - I am no longer using a Supratek - I had the Aesthetix IO Sig before the Supratek. I've tried many preamps lately and to be honest, you've got to spend a lot of money to do better. You guys should be very happy with these & feel no need to change.
That said, I do have gripes about the Supratek's and if those could be fixed, the units would be truly world class. I presume some of the mods that have been written about lately would resolve some of those gripes.
