This is just my own personal preference but I'm more attracted by build quality than SQ. Don't get me wrong, hifi gear has to sound good, but I find that it is harder to find an amplifier, CD player, DAC etc that doesn't sound fine provided the amp is well specified for the speakers. Get a great recording and some good well set up speakers and SQ is pretty much sorted. I just bought an all in one lifestyle system (oh the horror....) which performs fine. Great quality build however is harder to get and once you get properly high quality gear then why change it? And I don't think good build quality necessarily means expensive (though it might, not all that is expensive is well made but genuine quality may not have to cost a lot), in the 80's and early 90's a lot of entry level Sony, Pioneer, Yamaha etc gear was better built than expensive boutique gear. Hence why I bought a lifestyle system as a replacement working hifi for the lounge while I keep my nearly 30 years old Sony ES gear as my real hifi passion.
