Not long after I got a pair of ADS L1090s (very similar to 1290s but with ~7" dia. twin woofers instead of 8" ones. Then I moved to the Boston area and it was easy to get some factory platform/plinths for them. A year later I got some floor spikes for the plinths. This tightened up and clarified the sound. I towed the speakers in toward the sided of my head and got an improvement in imaging.
A few years later I got a VSP Labs Gold Edition very high current MOSFET amp. This was J. Gordon Holt's favorite amp when it was in production in the mid-'80s. It put out 200 wpc into 8 ohms, double that into 4 ohms, was stable down to zero ohms.
That extra power and current made the bass deeper, fuller, *and* cleaner.
