RE: Thanks for the answer and another question.

No receiver.

So, are you taking 2 channel audio out from the DVD player and inputting that at the pre-amp? If you are, the player should take care of the 10 dB gain for the LFE channel when it mixes things for 2 channel output. Just ensure that the player is set for 2 channel output in its setup menus and make sure you're using the dedicated 2 channel outputs rather than the L & R outputs of the 5.1 channel outputs and you should be right about the LFE gain issue.

If you're doing something other than simply taking a 2 channel audio signal from the DVD player, ie you're taking more channels out and sending some of them to something other than the pre-amp, then we need more info before anyone can give you any advice.

You talk about 'bumping the bass setting on the pre-amp'. If you mean boosting the bass tone control, then I wouldn't recommend that. Tone controls start to operate from a frequency well above the sub crossover frequency, sometimes as high as 1000 Hz. You're going to have an effect into the upper bass region, and probably even well into the midrange, if you use the tone control to boost bass. It will certainly boost what the sub is producing, but it's also going to boost what the main speakers are producing too. If you just want to boost the extreme low bass, then you really only have the option of playing with the sub's gain unless you're prepared to spend money and either replace the Luxman pre-amp with a HT pre-processor, swap your pre and power amps for a receiver, or (much cheaper) get a device like one of the Behringer products designed to provide bass equalisation and use it to provide the boost.

You should really only need to do that if your taste is for more bass in movies than in music. Otherwise one setting should really do it for both. Perhaps the simplest solution is simply to set the sub where you're happy with it when you're playing music and just leave it there. Over a couple of weeks you should adjust to that particular sound with movies and once the aural adjustment is made, any concerns about bass levels may vanish apart from the occasional movie where it seems as if the overall mix is a little bass shy, something that seems to be rarer these days.
