Depends. Anything more than a few years old, yeah. But if the source hardware and the amp/active speaker are both aptX compatible (Bluetooth 4.0), then you’re talking about audio CD-equivalent. That’s good enough for a lot of people. And if the system is capable of transmitting at the source and receiving at the amp/active speaker using Sony LDAC, then the SQ can exceed audio CD ... but it still won’t be as good as vinyl or hi-res digital over good wired gear. So, for some people it sucks, but most people probably won’t notice a difference. Just curious but have you listened to any “hi-res” digital yet? I was skeptical at first but Neil Young’s official “NYA” hi-res re-releases at 192k/24bit made me see the light. Errr .. hear the light lol. Now I've got quite a bit of hi-res audio accumulated - and it all fits in the palm of my hand. Pink Floyd Live at Pompeii in 96k/24bit on the OBFUSC/ATION Blu-ray is another fine example to sample, if you can scrounge it up.
