Question lang po. Ano best Audio source and speaker combination that is currently available sa market?
Sir, medyo subjective kasi ang question, for me it depends on the listener's taste/preference e.
For me, I'm currently connecting it to a PC via DAC then to the AAPJ tube amp, powering an 8" fullrange speaker set. I've also tried it on Audio Nirvana Super 8 and had great sound coming out of it (with surprising bass output). Gusto ko rin i-try with Markaudio fullrange next time
For me, a speaker with 90+ sensitivity will truly sing with these mini amps.
If you're into smooth jazz, vocals, instrumentals, classical music, this is the way to go (for hours of critical listening).
If you're more into rap, rock and heavy pounding bass, I'd advice you to look elsewhere
