I agree with Chad - It's absolutely the way to go. I'm using a TAD 150 Signature and am happy with it. It does have HT passthru. I have also used my Musical Fidelity NuVista preamp which does not have passthru. In that case, I run the front L/R into the Tape input, and set the volume knob at 12:00 - which is the point at which I calibrated my HT levels at.
It's easier if your pre has passthru, but only slightly so.
