Dose anyone know who's the SQ champ year '07,and is it possiable to know what equipments he/her is using..(just wondering)

There are quite a few IASCA classes.

TalkAudio has a few 'SQ champs' over the various classes.

BJ83 in rookie, Mcc also in rookie, Andy4k6 in street am, myself in street semi pro, andy bgsi in street pro, Nige in Ultimate pro....... the list goes on.

A rough summary of Orcas post would be something like this:

Source unit: Pioneer P90 or Alpine F#1

Amps: Genesis, DLS and Sinfoni

Speakers: DLS Nobelium, Hybrid Audio Legatia, Focal Berylium

Subwoofers: Image Dynamics, JL Audio, DLS

today there was a guy (in my country) wanted to trade his (new)power block sinfoni for my (new)ARC se 4000+cash!!! do you think it's a good deal
