IRX is great piece of gear for sure. I had one it sounded great with a powerstaion or into the return of another amp. Liked it so much I went on a Friedman bender and bought a BE 100D, PT20V2, and a JEL 20. I was never big on Friedman amps before but the IRX changed my mind... And the 3 amps I bought are all capable of being much more aggro and biting than any Friedman I have owned or played before. Seems he has listened to the feedback of many who have long said his amps sound too polished and smooth. They can do that, but these amps all have plenty of teeth if you desire..... My 800, and DSL 50 are collecting dust now.
