I posted this here since I believe that this is where most of you have the experience with MIT cables and 2 channel audio. I am in the market to upgrade my speaker cables and most likely will go with the biwire method. I currently have a set of 3.1tl's powered by a Mcintosh MC-352 /C-45 preamp.Hopefully I will also be aquiring a pair of 2.3tl's in the near future. Am I correct that the Shotgun S3.3 are not made anymore? There is a Shotgun-MA series which looks like it must be a few grades up as per the cost. Would the MIT model replacement for the S3.3 be the CVT-1 line. Has anybody had any experience or advice with the CVT-1's? While I'm at it, are most of you running your systems thru line conditioners. Any feedback on the Ultralink PGX line?
