Looks like the QX-5 Twenty will have digital volume control after all. I think this makes it an interesting choice if you have an all-digital library. QX-5 Twenty + VX-5 Twenty should make for a great combination.
Re: MQA - my guess is that record companies would mainly be interested in this from the marketing aspect - look it's 'high-res' (even though it seems to be a 'lossy' codec) but backwards compatible with all existing hardware as well as compact enough for streaming services. There's a lot going for it, but in the end, it's all a numbers game. Sonic performance is not necessarily the prime motivation.
