I have owned many MAC components during the 60s, 70s. I even worked for several high end audio shops during the time. MAC gear is good stuff made well but just not the best sounding gear for the money. Back in the 60s and 70s the MAC had tech that would travel their dealers and test and fix any gear they made that was quite nice of MAC. However, that was when Macintosh own the company and that perk no longer exist as MAC is owned by some Japanese company.
MAC gear is still built well and only the ultra high-end gear is built to a higher quality. Regardless of how much you love your MAC gear it's not the top sound gear buy a long shot. It's not bad sounding either just not near the top either. However, it's way good enough to listen to music. Would I trade my Pass Labs for MAC no way. So if you own it an enjoy it that is what counts, listening to music not to equipment.
