Pass labs X350.5 jumpers and Power cables

I just picked up a Pass labs X350.5. Aside from an annoying ground loop I left left to figure out it sounds very nice.

The Pass Labs web site appears to be down. I've tried all morning to ask this question.

I want to try some single ended cables I have but read somewhere that I would need jumpers of some sort, I'm assuming, on the input side of the balanced connections. Was this amp supposed to come with jumpers?

This was a buy gone miserable. The was supposed to be nearly new, not even broken in. Upon receiving this amp I noted a lot of scuff marks, a few scratches and considerable dirt and dust. Not exactly an 9/10! I digress.

I noted substantial differences rotating power cables. Is there a general rule of power cable when it comes to this amp?

Thanks!

The Pass has excellent bass quality, but everything matters. Your speakers, Amps, cables , power source etc.

IMHO, The Pass works better with unresricted power.
Please do not plug it into the PS audio Equipment.
Dedicated line also would help, but if not possible, limit the amount of items on the line that the Pass Amp is plugged into.

Dont use the balanced outs to a subwoofer.

I am using the RCA outs from my Preamp to the Fathom F113's . The Balanced outs go to my Pass Labs Amp.
You really should try this.
Actually, the Balanced is a ittle louder than the single ended and does IMHO provide a more fuller sound.
The Fathom F113's can always be turned up if need be.
More to discover
