for me it's very difficult to understand why this amplifier never gained much popularity. It really is a very nice sounding headamp for a very nice price.
Fortunately the people of Innerfidelity did recognize the qualities of the ROCK and Tyll even selected the amp for his Wall of Fame.
To celebrate this occasion I decided to have a special sales during the month of Mai. Just check my website. You won't find a better amp for that price!
