I recently picked up a pair of Def Tech SM55’s for $100 to use as surrounds with the $100 pair of BP2004 TL’s I also snagged. I have a CLR2500 from a previous system and the Def Tech system’s only purpose is for secondary use in my bedroom. I was reading reviews about them and came across this review as well as 3 others claiming bi-wiring really opened them up. I use 12/4 KnuKonceptz Kable for my mains and center channel as I really like the cosmetics of the wire but don’t believe for a second that biwiring them makes a difference. Upon reading the reviews I listened to the same tracks the reviewer did, using a similar source (iTunes through a MacBook Pro) and neither myself nor 3 other friends could tell when they were bi-wired in a blind comparison. Why do you guys think websites publish this stuff? If Emotiva and Def Tech want to start sending me review products I’ll tell everyone I can and scream it from the rooftops that bi-wiring shows the true potential of your speakers! Never mind the scientific measurements that prove otherwise!
