I’d suggest taking a look at the Musician Aquarius R2R DAC. I have their Pegasus, which is the next lower model, and unlike many R2R DACs it is very detailed and transparent up top while maintaining the other beneficial qualities of an R2R design. Thinking an R2R DAC would make for a very interesting comparison to your Chord, and if it doesn’t work out I believe you can just return it — thank you Amazon.
Here’s a good and thorough review FYI…

Just another option to ponder, and best of luck.
