A friend let me borrow a Driverack PA recently to bi-amp my hi-fi setup. I was using it to test in concept my plan to run 2 JBL 2235s active with a low pass cutoff around 80Hz, essentially creating a subwoofer. (I'm running the top section full range since it naturally rolls off around 80Hz.) The concept worked brilliantly. But based partly on threads on this forum, I decided to buy an Ashly XR-1001. To my ear, the analogue Ashly sounded much better than the digital Driverack PA. Note I was only using it for low end pass band duties, but the bass was much deeper and tighter. Frankly, I was shocked. It also sounded more natural. The controls are of course much easier to use to boot. Brought a big smile to my face.
