I’ll add that I’ve been working on upgrading PC with the help of the Cable Company (highly recommended). They recommended that I start with my power conditioner cable (big difference), the DAC ( clear difference, but not as big), pre, and amps (I haven’t done yet)—so down the chain.
I will also add, if you use digital, consider your inputs there. Going to a fiber system and good Ethernet cord definitely reduced glare (fiber did 90% of it for me).
