A little over 2 weeks ago a Rockna Wavelight replaced a Chord Qutest in my main rig. The Qutest replaced a Bryston BDA1 in March of 2019.
What has been gained: Wider, deeper, more holographic sound stage that extends well beyond the speakers. Even more highly resolving. Much warmer presentation (which for me and my system was a very good thing). A fuller suite of inputs and outputs including i2s.
What has been lost: The sheer cuteness of the Qutest's wonderfully compact form factor. The Rockna is a very good looking piece, but it is 17" wide and 12" deep. And a seriously deeper hit to the pocketbook.
