Suggestions Please

I have always owned high end speakers and amps. However, I have always used my home theater AV Receiver as the pre amp. Recently I purchased an Audio Research Pre Amp and Audio Research CD player and opened my eyes to a taste of true listening pleasure.

However, gone is the days of day of bass and treable control and I am now seeing that not all recordings are created equal. Albums I loved like "Rush Signals" has no bass what so ever, and Pink Floyd "The Wall" blows me away. I was trying to figure out where my bass has gone and on Holloween, I put in one of those spooky CD's and cranked it up. The constant heart beat was clear and solid bass that blew me away. Once again leading me to re-evaluate my music collection...

So, I am on a quest to buy some new music and I am looking for suggestions in Jazz, Rock, and New Age. Dynamic bass is where my taste is, so any suggestions would make my day...I do like acoustic stuff as well...
