The sale may already be pending but I can give you a quick comparison. The chain is from my P/C Gungnir D/S via USN (Gen 5). I believe both amps have stock tubes (the MCTH definitely does). Describing music through words is kinda like trying to paint a picture of what something tastes like, but I'll do my best. The DNA obviously has more of that (hard to define) tube-ish-ness people talk about, which makes sense since it's not a hybrid, and the MCTH is. The adjectives 'wet' and 'warm' never seemed clearly defined to me, but I'll say there's some more 'weight' to the notes, as well as a bit more perceived 'air' & 'room' in and around the music. The MCTH comes off leaner, but with a little better detail retrieval overall. The MCTH is more peaky in the treble, slightly sharp on some recordings. The stage feels larger overall with the DNA, not that the MCTH is closed in, but the Sonnet 2 is a step up. The mids are great on both amps, but I do prefer the 'lush' presentation with the DNA...as always YMMV. I hope I touched on all the salient points , but if there's something specific you were wondering about, let me know.
