Ideas for short interconnects.

Those are called jumpers and some cable manufacturers make them, Audioquest I think. This may make a significant improvement, there are threads here and/or on Audio Asylum that discuss the immense improvements jumpers like this make for the highly reviewed Creek 5350 SE.
Alternatively, there are small cable makers that advertise on Audiogon that might make a special order set for you.
Good luck,

VH Audio will sell you a half meter pair. I purchased a set from them at one time. They are flexible enough for your needs. As previously mentioned the RSAD cables will work as well.

I also have an integrated amp with pre-outs. Does this make a difference versus the stock jumpers? Phil Brady.

Phil Brady,
About twenty years ago I had an integrated Marantz amp with a 2-inch jumper. As an experiment, I replaced the 2" jumper by an extra high-end 4-foot interconnect I had on hand. The improvement was HUGE. I left the IC in until I replaced the integrated amp with separates 5 years later. To maximize synergy, try experimenting with several short ICs.
Best Regards,
John
