Ribbon cable inside amplifiers

I have been looking inside amplifiers on google images, newbie here…wondering if ribbon cable inside the amplifiers is a cheap way for them to build…I was looking at Pass Labs seem to have a lot of ribbon cables…


I had an AGI 511 preamp for years. It used a ribbon cable that went from the board to another board of the rca connectors. A popular upgrade for this was to remove the ribbon cable and use good quality shielded cable to each connector. A very large increase in dynamic range and overall better sq. Photos can be seen on line of the internals of this ribbon cable. A poor design when used within the audio signal path, ime. Many other upgrades were available as well, as mine was an all out assault. Thinking about it, I should have kept it, but I was offered a nice amount of $ for it, so it went. 

I wonder if Pass Labs use ribbon in the audio path?….

What if he does?? I mean it seems like you’ve just kind of randomly hit upon some feature of audio construction you were not previously aware of you are now fixated on. It’s a poor way to judge gear.

This is why I’m suggesting you build your own instead of arm-chair judging gear based on pictures and conjecture and an unexplained problem with a particular use of connection methods.

Listening to the amp is really the only way to judge his results. The proof of the pudding is not in the ingredients but in the eating.

And why are you fixated on poor Pass for using ribbon connectors?  Have you been looking at other amps too?? Lots of ribbon cables there too.

Years ago when modifications to Sony SCD-1 SACD players were in vogue I substituted harnesses of Audio Consulting soft-annealed silver wire for ribbons in the digital and analog domain to good effect.  But it's too much time and effort to repeat such experiments today.
