Ron,

As far as I could see on photos around the Gryphon bass towers are always placed in the same plane as the panels - it is probably why there is no phase control in the crossover.

Considering the Siegfried , phase errors should be negligible and IMHO you can forget about them at 200 Hz - the Siegfried's have very extended bandwidth for a tube amplifier (> 200 kHz) and can use switchable negative feedback, if phase error was high it would become an oscillator at high frequencies!

In your application IMHO phase and group delay are not an issue in your system. If needed the usually also very small phase shift of cables can be easily calculated - your preamplifier balanced output impedance is 50 ohm - see http://sim.okawa-denshi.jp/en/CRlowkeisan.htm. But for such long distances I would surely avoid some very high capacitance audiophile cables that can have capacitance as high as 300 pF per foot.:mad:

Thank you very much, gentlemen!

I have prdered two pairs of 50' Mogami 2791 interconnects with Neutrik gold-pin connectors and a B&K Precision 880. I will keep you posted!
