Of course the heart of the system consists of two amazing parts: SAM1HF and SAM2LF modules.
I'm very, very impressed with the HF modules. They have no horn-like deficits at all. It was a revelation to listen to them with my eyes closed (paradox, I know). It was a transporting experience, that exceeded my first encounters with the Performance Series Ti drivers by a mile. Now the PS Ti drivers got better--much better--after a few days listening, but I don't expect that the SAMs will, but who knows? In any event, the SAM1HF starts off at a higher level of performance that the PS can't achieve.
The real delight is the SAM2LF. It's a tough little f@#$%r that reminds me a lot of the HTPS400. It takes no prisoners and performs unbelievable feats. If the 800 Array is a fantastic speaker, the SAM1HF coupled with the SAM2LF is twice the speaker. Just mindblowing.
