@glassmonkey Amazing review! I think power is really important for these new e-stat hybrids. I couldn't get the trinity to sound good at all (sounded like a muddy mess) from my single ended Plenue M2 - even at almost max volume. A DAP or amp with balanced output is highly recommended. This was maybe influencing my decision to pick the Valkyrie as my favorite (I had not heard the WAVAYA Octa) as it's easier to drive. But that's a big deal for me as I'll either have to buy a new DAP or a separate amp (which is a deal breaker for me). Thinking about pulling the trigger on the Valkyrie as that e-stat high end is addictive - I genuinely struggled to take the thing out of my ears as it sounded so nice lol.
