I had a couple forum members, Mazersteven and MUDSHARK, over the other day to do some comparisons between my RBH TK-5 towers, Canton Ergo towers and the EMP Impression towers.
I made sure all 6 towers were level matched and used an RCA switcher to seamlessly choose which pair was on at any time. We played a very diverse sellection of music that included CD's that they brought. While the music was playing I was able to randomly switch between towers without them knowing which were in use. I would not tell them which set was on at any time (but they'd just get up and check).
After awhile they determined that the Canton towers were the hands down winner and easily picked out from the other two pair. MUDSHARK actually asked me to stop turning them "ON" during the first round since they were skewing his choice. So I stopped using them and just switched between the RBH TK-5's and the Impression towers.
When it was all over, I placed the Status Acoustic Decimo bookshelves into the mix. In the end it became a shootout between the Decimo bookshelf and the Canton tower. At that point it became a toss up. Both have great traits and crystal clear sound. mazersteven actually wanted them both on at the same time. "That's the sh*t", was the actual phrase used.
I've been hoping MUDSHARK and Mazersteven would post their thoughts. Hopefully they'll do it soon. Otherwise I'll try and summarize their comments.
