Replace Silver interconnect cable , please advice

Silver can even sound more musical than copper. It depends about the quality of the silver what is used. One thing is a fact that the best quality in silver Always beats the best copper in resolution, speed and drive. I use the Acapella pure silver XLR. This one is very dynamic and has a warm mid freq. I recently bought the brand new Audioquest Wild Blue Yonder with the new xlr plugs. Also this cable is very musical, with a very deep and fast low freq. Cheap silver cables can sound harsh and miss dynamics.

I tested many interconnects on Pass amps. You need an interconnect which can give a very sharp and realistic dimension of instruments and voices. Pass Labs give a deep and wide stage, but does not give the small and direct image you need. You need to understand all the properties of the stuff you own before you can choose an interconnect. Becuase they also have there own properties. For example; MIT and Shunyata make the stage also deep and wide and have the lack of a realistic dimension of instruments and voices. This irritating misstake is often made at shows.

Damn, How close are you to those speakers ?
Toe them in a bit and spread them apart if you can.
Also ,Can that couch go up against the back wall ?
That would help alot IMO. It seems to me that you are way too close . Now these are just my opinions ... just trying to help

Bo1972

so what model do you think are good match to Pass?

If I know Bo1972, I think he will recommend either the Diamondback or the WEL Signature.
