Thank you

Any chance USBAPP can support Tidal downloads?

For classical purchased downloads, two sites I find valuable: Presto Hi Res from the UK and eClassical from Sweden (mainly BIS label of Sweden). For Jazz, HD Tracks.

Took me quite a while to get my head around the SR15. After a week of use, I can honestly say it is the best DAP I've owned and I've had teh Astell and Kerns, the Sonys, the Ipods, the Fiio-the lot! I had an issue with the slowness of downloads to offline but I was advised to save the downloads...

Me too. Very impressed. The sound is great, powers my Oppo PM2s with no effort, my Shure 585s with crystal clarity. The only downside is Tidal management is a bit of a hassle (simple with Fiio X7ii) and the keyboard is for tiny people. That said, great DAP.

How long does it take for the A&K A&Norma SR15 to charge up?

Had the same issue with the X7ii. Great player, great sound but teh software really annoyed me. And I have had Fiio stuff for years. Had to sell it after a while and picked up the SR15. Just charging up now so I haven't had a chance to hear it.
