Burning CDs of downloaded music

Is there a way to purchase/download individual songs and burn them to a CD while maintaining CD quality (16 bit, 44.1 kHz)?

I currently use a home theater subwoofer in my stereo.  I am considering upgrading my subwoofer.  Since my only recent reference is my stereo, I am not really sure what high quality bass should sound like.  I looked at subwoofer reviews on YouTube and unfortunately, I only own 2 songs from their playlists.  My thought was that I would like to get to know those songs from the reviews on my system so when I visit stereo shops I would have a better idea if I was hearing improvements.  I am not set up for streaming.  CDs are my only digital source and my DAC only has one SPDIF input.  If I could create my own compilation of those test songs on CD, I could understand their performance on my system and use the same CD in a stereo shop.  

If I can’t make such a CD, is there a less complicated way to figure this out?  I’m sure the stereo stores will have streaming.  But that doesn’t help me get to know these songs on my current system.
