I hate when salesmen at audiophile shops question your taste in music. I didn't ask for their opinion on my music, I just want what they are selling and that is it, if they do, I generally leave because they don't deserve my business, either way, you can always go online and buy things. It's not my fault if they only listen to music to hear timbre and this and that piece of tiny detail instead of listening to music to enjoy it. I buy nice gear because it helps bring out every last little bit of detail even if the recording itself isn't that great quality, don't expect me to change my taste in music just so I can have higher resolution recordings of music I don't like and try to listen for details that I don't care for.
You listen to the music, not your gear. Music is always first place in importance on the audio chain. What if your favourite song was only available in 192kbps MP3, would that make the song not your favourite anymore?
Basically, get the best bit-rate you can find of your favourite music. Don't start listening to anything you don't like just for high resolution quality. And don't ever let a salesman put down your music and discourage you from buying good gear to enjoy listening to it with. It doesn't matter if your music was recorded in a basement, mixed and mastered on a 300 dollar computer and put on the internet as a 192kbp Mp3, if you truly enjoy it, the more expensive gear will only allow you to get better results no matter how horrid the sound quality of the song is. Ofcourse you aren't using expensive gear to it's potential, but if you enjoy the music with the gear used, that is the only thing that matters.
