Pass labs X350.5 jumpers and Power 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.

You can make those jumper pins yourself. Just grab some solid-core copper cables and cut a piece, strip any outer jacket, and bend it into an "U" shape. When my house was under remodel, I found tons of 12 gauge ground wires that my contractor was throwing away, so I just pick them up to be used for situations like this.

Pass amps have one of the best bass control, or I should say most realistic bass rendition, I've heard.

I am using a BMI Orca II Limited Ed. powercord. My buddy also uses one of the Shunyata snakes on his with a pair of Dynaudio C4s. It took him a long time to get the bass dialed in. But they sound incredible right now.

After some experimenting last night I found that the Pass plugged into the wall, a dedicated circuit using 10awg copper with a Furutech outlet sounded superior to the PS Audio PPP. Thanks guys for the confirmation.

Too bad about the balanced interconnects sounding superior to the single ended. I hope to prove that wrong as I wish to use the balanced outs on my Cary SLP-05 pre to the Fathom F113's and the single ended cables to the Pass. Having mostly home brews but of significant quality, I'll be rotating cables until I get a handle on what I'll need to further the SQ.

Anybody want to drop by with some cables ;-)?

I made some crude jumpers last night and used my DIY RCA's which sounded great. I tried another pair and whooah sounded like crap. I mean crap. I went to the back of the amp and noted that one of my jumpers fell out. Now I know what jumpers mean to this amp!

What I'll do today is to grab some gold pins from a Burndy trim trio connector and 3 twists of 24awg gold plated jewelery wire and make some jumpers. I try that against the simpler 12awg copper approach.

Thanks.

As the night wore on and I played with setup on the system and sub I found a really nice balance and settled in to some of the best sounds I've heard. I took a room measurement using the Mobile USB Pre and RTA software and saw an amazingly flat response. 1 dip at about 180hz with a slight bulge at around 50 which I could dial down with the Fathom. But generally flat from 20Hz to 20KHz where it dropped very suddenly. It seems the Esotar tweeters I'm guessing don't sing beyond 20Khz?

I've got some very nice power cables but not of the cost of the Shunyata's. Looks like I'll be looking at the used market soon for a power cable.

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.
