Currently using a fully upgraded Beresford BM mkI DAC to drive the audio from PC, CD, TV and IFI Zen Blue 2 LDAC into an old school G-class Hitachi amp from 70s. I upgraded caps and resistors on the amp, paired it with decent Klipsch speakers and pretty happy with how my setup sounds. I guess I owe the sound quality to the amp and speakers though, though the DAC isn't bad on its own.
Unfortunately the lack of the remote control in the system is becoming more annoying than it used to be, so I am thinking of upgrading the DAC to something more advanced.
The are plenty reviews on https://www.audiosciencereview.com and I'm considering Topping DX3 pro+, but maybe someone wants to talk me out or recommend another dac that sounds similar or better than my Beresford through RCA outputs. Headphone amp is't important, my headphones are connected to the amp anyway.
