Slee...welcome.

When you're in 6 channel bypass, the digital menu is bypassed.

The only way you'll miss LFE when in 6 CH bypass is if you haven't connected your player's analog SW out to the 950/ICBM.

If you have made that connection, the only way to avoid DB is to turn the analog BM switch to 'on'.

The easy way to remember that the digital formats menu doesn't apply (large/small, crossover, distance) with DVD-A/SACD is that it is Bypassed, thus the mode title.

It sounds like you are getting double bass the way you have it configured now, because the 950's analog BM sends a copy of below 80Hz signals from the sats to the sub and the stas at the same time when the switch id 'off'.

Hope I understood the question and the answer helps.
