What should be an upgrade over the FiiO A5? Nowadays I see a lot of dac amps with this form factor, but most of these are equipped with a dac as well. As my intention is hooking the amp with a dac. I have read lot's of positive reviews of the Khadas Tone Board. It's successor, the Tone 2 Pro seems like a major overhaul from the already very good KTB. just need something's to amplify the signal. Has audio gear manufacturers stopped releasing dedicated amp?
