To answer some questions:
Randyhat - "
BTW, what speaker cables are you using?""
I'm currently using a bi-wire pair of MIT Shotgun S3.3 Gen 3.
The universal iconn spades barely fit in the barrier strips but
are otherwise an extremely solid connection. I do have a bi-wire
pair of AudioQuest Volcano DBS cables but they would have to be reterminated as they have bananas on all ends.
tomic601 - "where did you source the bits from"
The Acrolink 6N-P4030 cable was sourced directly from Japan several years ago but is no longer available. The new Acrolink 7N-P4030 II is available from VH Audio as is the Furutech FI-50M(R). The Schurter 4781
is available from Revolution power. BTW, the FI-50M connector has made substantial improvements on every sub I've used them on. Even just cutting off the molded male connectors on stock power cords and implementing the FI-50M makes a great improvement.
I'm continued to be amazed at the resolution of the Quatros and the image/soundstage they throw, both on music and movies, is outstanding even surpassing my Nola Viper 1AX speakers which are noted for their imaging/soundstaging due to their open baffle/dipole mids and tweeters!
