If I had to pick out weaknesses, I’d say your dac, usb reclocking and using Tidal.
The DAVE is a big upgrade and it sounds great with a WA33. Your USB connection could be “dirty” so a usb reclocker would probably be a nice upgrade.
Tidal uses MQA (which Chord Dacs do not fully support) and does not have as large of a collection of hi-res albums as Qobuz. Most of the time, for the new albums I listen to, Tidal is not Hi-Res, but Quboz is (I’ve found it to be quite a big difference in hi-res album availability).
To piggy back on this as well, I 100% agree with Cigg here. I found Qobuz to be better when it came to both sound quality and availability of Hi-Rez content. You can also buy Hi-Rez music at discounted prices through Qobuz with their sublime streaming plan (they just significantly reduced the cost on sept 1st). Most of Tidal’s Hi-Rez content requires MQA compatible devices to be used to its fullest They also do not offer the option of purchasing music at all.
Lasty, if you are investing a lot of money in a high end system I personally think you owe it to yourself to at least consider investing in locally stored content, especially in .wav or .aiff formats if you can manage it. The differences in sound quality can be quite significant over Hi-Rez streamed content. Local > Qobuz > Tidal
The source can make a significant difference in a system as can the content you are playing with it.
