I don't have any experience with HT, but found AP-9's to be a huge disapointment. Some describe it as nuetral & smooth. I found it to be veiled lacking detail & dynamics. Believe it or not, my AQ midnight III blew it out in every respect. Perhaps it would be a good match in an overly bright system, but I even doubt that.
Analysis Plus vs. Harmonic Technology
I have a Plinius 8200 integrated, Arcam FMJ23 cd player, and B&W CDM9NT speakers. Shunyata Sidewinder Golds on both pieces, and an Audioprisim Foundation 3 line conditioner, using a Shunyata Mojave power cord for the Audioprisim to the wall. All cableing is Analysis Plus. I'm not getting alot of extension, I was thinking Of Harmonic Tech. Pro-Silway mk.2 and Pro 9 plus speaker cable as an upgrade. Any ideas? Thanks.
