I don't think it would be worthwhile, especially if you continue using the BAT as only a transport. If you're happy with the sound, keep it. Maybe send it to BAT for the 24 bit digital upgrade. If the upgrade bug does bite, and you do buy another DAC, I would sell the BAT and buy something else as a transport. I have a VK-D5SE, and I like it, but I believe it's tube analog output stage has more to do with why I like it then it's transport.
