The sub trim should work as described on the HPF/LPF analog crossover. What should not work is the x-over point. It should remained fixed at 80Hz.

For me, this really opened up a whole new world of enjoyment with my 970 for two channel listening -- both on CD and vinyl. I think you'll find the preamp section of your 1070 is surprisingly transparent and really gets out of the way of the signal path. It also opens up a host of possibilites for addtional tweaks and upgrades for 2-channel performance. This includes the aforementioned outboard DAC option, as well as adding an outboard phono stage. Or if you've really got the upgrade bug, consider a finesse, two channel amp for your mains and hook it up to your L/R pre outputs.

You read my mind w/ the amp and turntable.

Unfortunately I'm out of space in my entertainment system (see below). The wife is open to replacing it with something that I can (stealthily) add components to, so I have to fix my little problem first...I already caught hell for stacking components (my Toshiba and Denon players) on TOP (god forbid) of the furniture.
