Here's the breakdown:
Monster HTS 5000 MKII power station
B&K AVR307 A/V receiver at 185W x 7 into 4 ohms
Zenith DVB-216 DVD Progressive Scan
Sony 51" HDTV ready monitor
LSi-F/X side surrounds
RT35i rear surround
Samson S1000 500W subwoofer amp
SVS Ultra subwoofer
I helped him calibrate it with my B&K SPL meter and the AVIA disc. We also ran a few FR sweeps on his subwoofer.
We played a bunch of stuff at reference level. We were seeing 117 dB peaks on the bass. The subwoofer is very impressive - very clean and powerful and seemingly limitless headroom and never sounding strained even at ridiculously high playback levels. It absorbed 500W and laughed at us.
I didn't have time to REALLY sit down and evaluate the LSi series on some classical, but my initial impressions were of a very detailed and neutral sound with excellent depth and stable soundstage. That Vifa tweeter is very impressive.
Overall, a VERY nice system.
