Angry Pre-amp for TA2022

Does ta2022 need a pre-amp?

I found most ta2022 board has a ne5532 pre-amp, some have not.

If connect ta2022 to usb sound card and cd player, is the pre-amp required?

Thank you.

I find I need a pre amp to get full volume with a CD player.

Unless you can alter the gain of the amplifier you will probably need a pre amp.
