Best quality Hi-Res download store for UK

Hi there

New user here (hello), hoping someone may be able to help.

I’ve been reading the forum for a few weeks now and I’m about to buy my first few Hi-Res albums. Just wondered which was the best place to buy from, if they all the same quality or are some better than others?

One of the albums I want is Michael Jackson – Thriller which seems to limit me to Qobuz or Onkyo Music/Technics Tracks (which I assume are the same as they’re both powered by 7 Digital). HD Tracks list the album but don’t offer the FLAC Hi-Res in the UK for some reason.

Prices are similar between Qobuz and Onkyo so wondered if one offered better quality (or is there another store I should be looking at)?

Appreciate any help you can offer.

Kind regards

David
