Kris,

thanks. Here's what I have:

>>There is a caveat: The combined input impedance of the power amps must be at least 10 times the output impedance of the preamp. Otherwise the load will kill the sound of your playback.

I use a mixer as a pre-amp and it has two master outputs. (+6db 2V) is a switchable 6db gain for each output. I currently use the 0db setting.quoting specs from the manual:
"
Outputs Level/Minimum Load
MASTER (BAL) 0dBV/600Ω 1V (+6dB 2V)
MASTER (UNBAL) 0dBV/2.2kΩ 1V (+6dB 2V)
"

not sure what "minimum load" means.

and my three amps have the following input impedance:
Jeff Rowland has selectable: 100k, 20k, 600 ohms
Arcam Alpha 5 - "unknown" but can measure
Spectron 1KW - will need to measure

>>BTW - what is your opinion of the delay capabilities of the DBX crossover?
I have not extensively (avoided) used the delay functionality. I had delayed the subs. The function works very well but I am not sure if it screws up the sound out not. I think it's good for subs. I have not used it for mids or highs, I aligned those channels physically.
