On that last point, don't sell your preamp so fast. I have a 380 and a 39 that I just had upgraded to a 390s. I too was considering selling my 380 and running the 390 direct. I have run it through the 380 to my 332 using balanced cables and compared it to the 390 driving the 332 solo.
Depth of detail and dynamics were significantly better running through the preamp compared to running the 390s direct. The 390 direct sounded good but the 390/380 combo was far and away more engaging.
Just my .02
