Hi,
I own a IA-7 V3.
Before buying it I was actually looking for some speakers, and was auditioning the Gallo Ref 3.1s with Ref 9SE V2. I had never heard of NuForce or listened to a class D amp at the time, but was immediatley struck by the musicality of what I heard. Neither solide state or tube were my ears/mind hearing, just music. Just as I was about to leave store the shop owner said that he'd just received the IA-7 V3 and wondered if I'd like a demo. Wow, the depth, staging, dynamics and tonality of the amp was amazing. The speakers we hooked it up with being pair of the huge Usher CP8871 with 2x8 inches bass woofers, didn't make it less astonishing. In short, I ended up buying it and I'm really satisfied.
