Hi all--new to register but long time lurker. Just getting back into hi-fi listening and wanting to get a decent amp for my system (Topping E50 dac, JBL stage 530 speakers, SVS p1000 sub w/WiiM wifi for streaming HD music). If it matters, I like to sit about 8 ft. from the speakers in a 12x18 room, and most of my music is high dynamic range. I'm looking for a sub $1500 integrated amp that has an adjustable (or at least multiple fixed setting options) high pass filter so my 530s are taken off the bass frequencies. Ideally I'd like the sub to handle 100Hz and lower, but I'd settle for 80Hz. Any suggestions?
