Default Upgraded Jumpers for Integrated Amplifiers?

To help get this integrated forum going ...

Does everyone here recommend using upgraded "cable" jumpers to replace the default jumpers provided by the manufacturers?

How about on the MA6600 in particular? Has there been any particular success with any one jumper?

What are the options? I see that Cardas has a nice looking jumper pair.

Cheers

I started a post on this topic a couple of months ago and subsequently purchased the Jena Labs Dussy jumpers - which did make a considerable difference.

Newb mistake not to search for the answer before posting a thread. Sorry! It sounds like the Jena Labs offering should be on the short list.

Has anyone found any alternatives to work well? Any synergy with a particular set of jumpers and the ma6600?

I shouldn't imagine that the results from using the Jena Labs Dussy Jumpers with the MA6600 would be much, if any, different from those realized with the MA7000, which were significant.

The amps are similar, and I imagine the results would be the same.

kfr01.......I would imagine replacing the stock jumpers on the MA6600 with a quality pair of interconnects would prove to be equally advantageous, as well.

I experimented with several different brands of jumpers on my MA6600 but I could not hear any difference.

BuffaloBill.......Did you stay with one of the tested jumpers or return to the stock jumpers?

Anyone tried the Cardas?

My XLR cables between DAC and Pre and Pre and Amp are Cardas, and I've been favorably impressed with their neutrality.

Put in the Jena Labs jumpers and could not hear any substantive difference in sound, but did not do a serious A/B listening test (too much effort for a $70 tweak - installing and removing RCA terminated jumpers is a pain).
