DartZeel CTH-8550 vs PS Audio BHK 300 Mononlocks

I know this is a crazy comparison but I am currently trying to decide between the Dart 8550 Integrated (used) or a new set of BHK 300 Amos with the BHK Pre (new). I am currently upgrading from a Yamaha A-S3000 and like convenience of the integrated but feel like the BHK monos might be a bigger upgrade. They will be fed by a VPI HW-40 turntable and a PS Audio DirectStream and will be running a pair of Joseph Audio Perspectives.
