As a dealer, I hope you'll pass on these comments to McIntosh. Perhaps they'll listen to you. I wish they had crowdsourced this decide. It would have generated a lot of attention and provided them with valuable feedback. I wonder whether anyone on the design team actually uses a portable USB DAC/headphone amp,
As it is, I'm a bit torn. I've been a fan of McIntosh gear for some time, but it's generally been a long distance affair, since I've never been able to afford their products. Finally they come out with a product I can afford, but it's missing a few key features. I just purchased a set of AptX HD compatible headphones. If the MHA50 were AptX HD compatible, I'd probably buy it - even if it lacked MQA decoding, which is another feature that's sadly missing.
