Queensrÿche | The Warning (Remastered / Expanded Edition)

Jethro Tull | Aqualung (Steven Wilson Mix and Master)

It does have the option to up-sample using SoX or r8brain, with multiple available parameters. Don't know if it's the same as HQPlayer, but it's very usable.

To be fair, regardless of the noticeable (to me anyway) sound quality bump with Audirvana, if you have other requirements, Roon may be the better choice. For example, if you have multiple streaming endpoints (multi-room configurations), Roon is very much engineered for that use case. I don't...

Audirvana doesn't have a built-in EQ, so you'll have to find a plugin you like to do the job. FYI: The Audirvana Forum is a good place to ask about plugins and such. https://community.audirvana.com/

I've been using Audirvana + Qobuz for about 2 years now, and even with the additional expense of the SaaS subscription model for Audirvana it's worth it to me for the sound quality. I hope you find it worthwhile as well.

Can someone remind me of the differences between the A, B, & C flavors of the firmware?
