Having owned both as well, I'd say May and DAVE are literally on opposite ends of the sonic spectrum. They sound fundamentally different the way music is rendered - I wouldn't necessarily say one is better and most will have a strong preference one way or another, I too much preferred the May but DAVE is absolutely on the same level. OP if you can stretch just a tiny bit or buy used, my first pick by far would be the Mola Mola Tambaqui then upsampled with HQP, it is unbelievably good, it's basically all the strength of the May and DAVE combined. However, whenever you're buying integrated especially where the primary function is the DAC, the headphone amp if included is usually tacked on as almost an afterthought and a definite bottleneck.
