Integrated amp: jumpers versus cables

I assume we're talking about the jumpers in the pre out/main in section of an integrated amp and not the jumpers on a bi-wire speakers.

If they are designed as kind of an on/off switch to merge the amp and preamp sections together, then how does it affect the sound whether or not you have an IC or jumpers?

What about the integrated amps that work without any ic's or jumpers in their path? Are they inherently better sonically because they operate without any jumpers?

Whatever you'd like to believe you'll hear, you'll probably hear.

I spoke with Bryston service about this when I owned a B60 integrated. They said don't bother. I tried jumpers anyways, it sounded a little different, but worse. I don't think it will help any....

It has metal jumpers--I think they may already be an upgrade from the originals, not sure. I have twice read reviews of this same amp which recommended going to IC's.

I"m just looking for the best connection possible (without spending an arm and a leg)

thanks to all responders.

You might as well try it. Chances are you'll keep them in and eventually use them for you next integrated. If you even had to ask, chances are you can't stop yourself from getting them anyway.
