Nope no contact from them (though if anyone from mqa is reading this I would still be keen to speak with you to sort out some tests that would be agreeable to both.)
One reccuring theme I've heard from various manufacturers is that mqa is becoming quite... Pushy about how not just mqa, but non-mqa content is handled.
This is a direct quote from a manufacturer that spoke to me:
"Now, the MQA file, un-unfolded, is usually a 44.1kHz or 48kHz file, while unfolded it is played at the highest sample rate supported by the player that is a multiple of these rates (so e.g. 352.8 / 384kHz / 705.6 / 768kHz). There are few to no DACs out on the market that can handle a switch from e.g. 44.1kHz to 705.6kHz without an interruption to the sound, well, I should say I am not aware of any such DAC and certainly none of our company's devices have one, not even sure if it's theoretically possible. This is the reason for the interruptions to the sound many of our users are reporting when beginning to play an MQA track, seeking through it, skipping to another track, basically anything other than playing a whole MQA album in sequence.
Now, MQA understandably do not want to want this to happen to their audio, so the recommendation to all of us, is to resample all incoming audio to their highest 44.1 / 48 multiple, regardless of whether it's MQA, in a manner consistent with MQA unfolding so that no break in the sound would occur.
If we followed this recommendation, we would have to abandon the [name redacted for company anonymity] for bit perfect rendering of PCM audio at different sample rates."
