Bluetooth is lossy. Consider a DAC (Digital to analog converter) instead. This one has served me well: https://www.parts-express.com/dac-digital-to-analog-audio-converter-optical-—coaxial-—usb—180-998 Much much better than Bluetooth. Nothing gets lost in translation. 24bit / 96khz
I'll be glad the 1250 is back in service come winter - those heat sinks aren't just for show. I should build it into a coffee table and use it as a foot warmer. ;-)
