The system sounds better all the time.

Finally got the four Platinum bypass caps in the 2nd amp and also made another left-channel preamp-to-poweramp IC. This is of Neotec UPOCC-silver NEI-1001 (?) and KLE Innovations Absolute Harmony highest-quality solid-silver RCAs*.

Also started removing the SuperSubs from the front wall.

Tonite we pulled the drivers and then the front panels which left the hollow boxes lined with 2" plastic foam. The subsequent mild damping of the rear wave from the Super-7s has improved image placement and solidity and reduced instrumental blurring, thus improving transparency.

Will be building some panels combining broadband absorption and bass trapping for those about-3'-wide-by-6'-high soon-to-be-blank walls.

HOT DAMN it really sounds better!

* The KLE Innovations connectors are the successor to the Eichman plastic-bodied, low-metal-mass RCAs of years ago; see link.
