I recently bought a nice pair of 1980 Heresy speakers. After refinishing tge outsides I took Michael Crites recommendations and replaced the capacitors, mid horn gasket and the tweeters. I thought they sounded great before and to me they sound great afterwards. I’m not able to discern the differences. I also purchased a Willsenston R300 tube amp. I have experimented with my Amazon echo as a source by just telling Alexa to play something. I’ve Ali connected my iPhone to the echo dot via Bluetooth. And I’ve also connected my MacBook Pro directly into amp. My perception is that the MacBook direct produces the best sound. I want a simple system. I like the convenience of telling Alexa to play something, but I’m not wedded to that. All of these devices must have a dac, correct? If I connect my iPhone via Bluetooth to the echo dot is the dac in the iPhone used or the dac in the echo? Ken Rockwell suggested to me that Apple’s DACs were very good. How do I keep it simple and get the best quality sound? Thanks for your help.
