Pass labs X350.5 jumpers and Power cables

When I got my second Pass amp, the jumpers were missing. The kind people at Pass sent me some, free of charge. Cardas also makes jumpers, if you feel the need to pay for them.

Like Zenieth, I use a Shunyata Python with my amp.

Sorry to hear your experience so far has been frustrating. Hopefully, you will like the X350.5 with your system. IMO, it's a great amp.

Playing with the system last night I was rotating interconnects and power cables looking for a good balance and what the Pass is doing in my system. A few quick observations. I cannot get the bass where I want it. This could be part of the Dynaudio C1's character and I was hopeful that the Pass's current would solve some of the woolliness, and it did to a certain extent. My ears are still accustomed to the line arrays which do bass. Oh my do they do bass. And they do it with lots of drivers.

I tried plugging the Pass straight into the wall, bypassing the Power Plant Premier. I think I like it better without a regenerated AC. I'll have to revisit that scenario.

The C1's I think sound better with the Pass than do the line arrays. The Nuforces through the Power Plant Premier to the line arrays was breathtaking at times. I could have left well enough alone.

I'll check room response today with some RTA software and a mic. I can see a second sub in this system.

The front panels of the amps are pretty beat up. I wonder if Pass doesn't refurbish front panels?

Thanks for your opinions.

The Pass will probably work better with balanced cables.

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.

I also confirm that Shunyata Anaconda or Python work good with Pass amps. In addition, I had quite satisfactory result with Exact Power EP-15A.(AC Regenerator-filter)
I also recommend XLR cable use over RCA.
