McIntosh MHA50 MY REVIEW. “The McIntosh MHA 50 is amazing” JH
I just received my MCINTOSH MHA 50 that I have been waiting for many months. The performance with my AUDEZE MX4 and AUDEZE LCD i4 headphones is amazing and may even surpass the performance of my $2600 HUGO2 CHORD DAC/amp. With my Tidal Hi-def iPhone streaming source the sound is amazing. Using the free app C CONNECT MQA sound is even more amazing. The question ultimately which is better the McIntosh MHA50 or the HUGO2 Chord I give the edge to $700 McIntosh MHA50 believe it or not. In my opinion the sound is a bit more warm or “tubey” and in general more satisfying. Some audiophiles may say it is a toss up and others that the Hugo2 Chord outperforms the McIntosh MHA50. But I am firm in my opinion. You decide for yourself and a/b the two yourself.

What is the est ship date?
Lisa J on Nov 29, 2017
  We don't have a firm ship date just yet.
It does not mention MQA unfolding, as a feature, which would indicate it does not do MQA. However one of the customer reviews mentioned a free App, that purports to do MQA. Is it a McIntosh App for this product? If so, I presume it would do the second half of the unfolding process for MQA files on TIDAL ( TIDAL does the first half). Does anyone know? The App is called ' C CONNECT MQA'.
A shopper on Jun 9, 2020
  Thanks for your question. The McIntosh MHA50 has no MQA capability.
Would this work inline to a Playstation usb port? I'm sure it would work with the wireless or wired connection from the preamp the PS4 HDMI is already connected to but I am considering adding a monitor set up with fewer components and I'd like more flexibility with headphone options (eg. Audeze LCD-GX).
