Yeah, I contemplated picking up your 75.2 but I would need like 4 of them lol. I need these amps to power 2 sets of Boston Pro 60s @ 3ohm each. I was lookin at the PPi 4800 or whatever but I want these amps to match the Treo 3.1s... I noticed you were also interested in the 3.1s before I got them. You shoulda got em - it was a great buy. Weird, I cant find even 1 other person with the 3.1 amps though. Or even someone who has owned them besides Tuan and Kevokrook.
