I did something wrong with my amp, a Parasound HCA 1500a. Actually I have been using the Looping Inputs, which are designed to send the stereo signal on to another amplifier, as main regular input. I mean I connect my preamp output to these looping inputs.
When I got aware of my mistake, of course I corrected it.
Can I have damage something in the amp? Everything seems to work ok.

Beside, I have to turn pretty much my preamp knob to get loud volume, but this might have been always like this and I?m noting it now because I feel I did something wrong?

Thank you.
