I've had my 990 for the past few months. Excellent. I just hooked up my new 7125 on a temporary basis until I get some properly sized interconnects. I have a few XLR to RCA, high quality interconnects (have to buy a couple more),which would be perfect to tidy up the rat nest behind my rack. Are there any drawbacks to doing this? I kind of think it should be OK, but I am far from an expert. Any feedback would be greatly appreciated.
