This amp is so good that I bought 3 of them for my home cinema, together with a Denon AVP A1 preamp.

It sounds incredibly good, with hermetically-sealed Celestions class A

Slightly better than the LV-91, which doesn't feature the subsonic.

If anyone is selling one of these gems, I'm really interested and offer a good price.
To sum it up, I recommend this model to anybody who wants a clear and powerful sound (but pay attention to the high impedance, 8-16 ohms)
