For DAC/streamer you must avoid expensive product like dcs and mbs and you should start with well engineered product. For amplifier you can stretch as they may sound deferent compare to dacs.
I would suggest matrix dac/streaming x https://www.matrix-digi.com/en/products/321.html
Or DAC only like Topping D90.
