All points of view are relevant and valid, but for me the Q5 is anything but meh, it sounds fantastic. If you are going to compare it with full-sized, or mega-buck rigs you will hear a difference, but that can be due to expectation bias. I have been around here a long time, lurking even before joining in 2011, and I have been into audio gear since the 1980s. When it comes to reading impressions of entry versus high-end gear I have NEVER, EVER, read somebody not find the more expensive, or full-sized gear that costs more and looks better as sounding better. Never, people always hear the differences. Sure, in theory it could be because the differences are there, but it could also be that we are conditioned to expect bigger, more costly gear to sound better.
Anyway, my point is that I don't hear the Q5 as meh, and I know that for some they will never believe that small footprint devices can sound as good as their full-sized counterparts. I also freely acknowledge that there can be small differences that are audible and different people will respond differently so the poster who said the Q5 is meh, absolutely valid for him or her, not questioning that, but I am so glad that has not been my experience. To this day I consider the Q5 one of the very best purchases I have made in this hobby. No regrets here.
