Bypassing / Jumping Pots? Ex: Rotel RB-1050 or Parasound HCA-1000a

Hi Gents, what is the general consensus on removing pots from the signal path? Looking at an RB-1050, there are two pots for each channel at the front, introduces wire, probably signal quality loss, and would do nothing for me.

Conversely, when looking at Parasound's HCA-1000a, there are 'THX Level' pots at the back, throttling the input..

In either of these cases, what might the procedure be to remove these pots from the chain, simply jumper?

In the case of the Rotel, I found the schematic here:

Parasound, I was able to find this photo of the back of the pot/input board:

Appears to me the Parasound is a significantly better amp, but interested in your thoughts on this too.
