Good luck to whichever your choice. I also started with H1 and was looking to upgrade. Tested the TT and then the Dave. I cannot remember the TT signature now but recall it being an improvement but not as wow-ing as when first listening to the Dave. From then on, chord now have mojo, poly, h2, qutest and blu2, and possibly more to be announced at the Munich show. I would advise that you choose one for your use case. Even if you don't need it on the go and need to move it between setups, then quetest or h2 might best fit you depending on whether you need the pre and amp sections. I'm not a fan of using battery powered products for purely desktop use, so if the use case is purely for a single desktop setup, then Dave imo is the way to go. There's much discussion on bluh2, bludave and possibly bluqutest, and speculations of standalone m-scaler. My personal take, bludave is still at the current pinnacle. If chord cannot fulfill the demand for the blu2, I don't really see them releasing a standalone m-scaler; and even if they do release one, I don't believe the price will be significantly lower as what many are hoping for. You can of course also wait till the munich show before deciding on your next move, since it's just a few weeks away.
