From my experience with Chris Johnson @PCX, I would investigate the SE+ upgrade. I had SF Power 3SE+, SF Line 3SE+ and Benchmark DAC-1 XLR mod from PCX and all with EXCELLENT results.
I heard the BAT vk-5dse in a friends system that not familiar with so can't comment. He did mentioned a problem with the transport in reading disks and difficult getting it repair from his dealer.
