Adcom preamp question

I just added an Adcom preamp to my 2 channel system. Assuming I don't want to use the bypass outputs, how do I choose between normal and "not" normal. I read the whole thing about bandwidth and dc current, and didn't get it. I'm running it with a NAD amp. Thanks.

    Lab is full full range from like 1hz to 100hz. Normal is for amps that don't have tremendous range. I had a GTP-500. Too harsh. Excellent bass slam though.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.

    GFP 565 with 3 different main outputs. I'm using normal because, well, it is normal.

    I did the same. It puts less stress on amps that are trying to reproduce inaudible frequencies.

    'Of 3 line outputs the only difference between 2 of them is, one is direct coupled and one has a bypass capacitor while both are connected directly after the tone control defeat and highpass filter switches.
    The 3rd is connected before these switches.'
    I use 'Bypass' because it has sounded best to me. Every time I switch to each of the others to play with tone & loudness I feel the sound loses some drive which the added controls can't compensate for..
