I so feel you, man. The stack thing - went there, it was a nightmare. Just not functional in any sense - connection was unreliable, my phone became an unwieldy monster, and with the Q1MkII form factor it’s even worse since it obscures the lens... plus what you write about the 3M expenses, I mean, seriously, stop doing that to yourself You have plenty of gear already, so I don’t think your Ali basket will bring as meaningful an upgrade to your listening experience as the ES100 will. It’s seriously transformative! A much better solution than a dedicated DAP with all the shortcomings those have. I have a V30, which is like a great midrange DAP and a fully functional phone rolled into one, and even that elegant solution is often less desirable than using the ES100.
