McIntosh mc452
yes. I tried it. It really sounds great. Bought some good grade speaker wire from Audioquest and some good spade lugs. Ran all new wires.... four sets. from the amp 4 ohm taps to the mids and tweeters and from the 8 ohm to the woofers. I think it is significantly better clarity, separation, etc. I was using the jumpers previously, not bi-wired. I wanted to get a little feedback before trying. But I'm a believer now. Thanks
