I've been using the web player for Qobuz, and it appears to allow for high quality output--I'm streaming at 24bit/96kHz at the moment (though I'm no audiophile, so I guess I can't confirm that's what I'm actually getting).
And apparently Qobuz pays the most per track of any streaming service, which is cool. The only thing it doesn't have is customizable "radio", but otherwise it's solid.
