Janeb, which dealer/retailer advised you in building your current audio system? Why did you opt for the Coltrane supremes and not for any of the other speker systems you listened to (what do you mean by the power requirement of the the top of the line Kharmaspeaker? The Edge poweramp you are using is powerful enough to be combined with the Grand exquisite? Were you able to compare the speakers under more or less the same conditions or did you visit different audio shops?
Janeb, as you probably know the speakers need at least 400-500 hours of playing before they show what they are really up to. What kind of speakers did you listen to/take into consideration before you decided to opt for the Coltrane Supremes? Could you give us some thoughts about the tonality of the system used in combination with solid state amplification? I am using tubes myself.
I am the owner of a Marten coltrane supreme system as well. I am wondering how long you have been playing your coltrane supreme system and are you happoy with it?
