Tube DAC on the way. Went with a simple Maverick TubeMagic D2. Will update with impressions on how it changes sound once it arrives, with pictures of course.
Also considering getting a simple tube amp that acts as a pre-amp and headphone amp between the DAC and Emotiva, so that I can tap in with normal and/or high impedance headphones when not using my Hifimans, and also to see how a tube as a pre-amp might further affect control of volume and sound in general. Maybe a Little Dot MKIII or Dark Voice 336SE. Thoughts?
