I have been using this amp for 1,5 year now. I had to get used to the sound for some time. It is a real valve sound with a very spacious, sweet sound which mostly gives a very exciting captivating, listening experience. I hear a lot of new things in the music. Because the midfreq. are not emphasized it is a very balanced sound. Vocals are really amazing, depth of space is sometimes unbelievable, Very unfatigueing and coherent sound.
Although it is the best amp i ever had, and i am very satisfied with it, i know there are some (much more expensive,) better valve-amps which give a bit more dynamics and stronger bass. So 4 stars. Considering the price it is a bargain (5 stars).

Prev amps: Pioneer SA 500A, Sony TA 3650, Harman Kardon PM 665 Vxi, Audio Innovations Classic 25 (valve).
