My 2 channel upgrades are nearly complete. This thread proved to be a valuable tool in selecting amps and convinced me to buy speakers without an audition. Thanks to all for your contributions.
The DI's with upgrades have 60 hrs of run time and are sounding excellent with an LM508IA 48W SET. This is a beast of an amp and could have easily sent me to the chiropractor. The sonics of the Devore O/96 and LM508 setup heard at Pitch Perfect while impressive, don't really have much on the DI's. The bass definitely sounds tighter with the DI's and images are better defined but that is usually attributed to the Live Dirac hocus pocus I run. Tonal accuracy may be a smidge off compared to the O/96's but again, the DI's sound more live.
A notable also ran is the Raven Blackhawk. The vocals were wonderful with plenty of high frequency shimmer. I would have kept it, had it not needed a repair. That was my opportunity to upgrade, yet again :(
