This really deserves a new thread, but all this talk of classic bassists leads to the problem of getting hold of their old recordings (many probably never reissued on CD) and properly playing it back. Few people get good bass from their old LP's. I've been buying stereo gear since the 70's, and the following does the best job for me on vinyl LP bass reproduction at a decent (not cheap) price:
1. Grado cartridge. Nothing beatss a Grado in their lower priced models ($300 and less). Mount it properly in a decent tonearm (Audioquest, Rega, etc.)
2. Belt drive turntable without servo feedback. The servo feedback type (Technics) tends to cause "hunting" of the proper speed. A hefty motor and belt drive is the audiophile standard for pitch stability. VPI makes a variable speed control you can hook any belt drive turntable to. Try to get a heavy platter with record clamp as well; it damps resonances and cleans up the bass a lot. My VPI turntable uses thick machined acrylic for a platter.
3. A tubed phono amp. Tubes in early amp stages preserve natural timbres. You can buy separate units now that you can add to a line stage preamp. An old tubed preamp can also be used just for the phono section; use the outputs in the recording loop to bypass the line stage section. Better line stages exist in modern preamps. Some modern solid state phono amps are OK.
4. Modern solid state power amplifier. I have listened to quite a few tubed power amps, and they tend to lose control in the deep bass, no matter how well they sound otherwise. If you could afford something like one of the big Conrad-Johnson Premier series tube power amps, that might get the job done, but they are muy expensivo. Their solid state MF series does a killer job in the bass department, and they are the best solid state I ever heard that Joe Six-Pack can afford. For some unexplained reason, they always languished in the shadows of their tubed brethren and are available at good prices on the used market. They outperform the MV series tube amps in the bass and never need tube changes, and are commonly available on eBay. An old B&K or Sonographe power amp can't be beat if your budget is tight.
5. Modern remote controlled preamp, because I like to vegetate in front of the speakers. If you are on a tight budget, an old B&K Pro-10MC is the value standard, it has a phono stage but no remote operation. Sonographe is also good.
6. Your favorite set of speakers. Everybody's ears, homes, WAF (wife acceptance factor), budget, and sense of style are so different as to make a firm recommendation useless. I like Vandersteen.
7. Buy this even if you buy none of the above: Orbitrac 2 record cleaning system by Allsop ($40), Audioquest antistatic record cleaner brush ($15), and Discwasher SC-2 stylus cleaning system ($10). The best you can do without spending $500 on a motorized wet vacuum cleaning system. The LAST Factory makes the best record and stylus preservative chemicals. Change that worn stylus and take care of your records at all costs!!!

The amps tend to be the most expensive part of the equation, and Conrad-Johnson has the best website that lists all their past production models, all of which they still service and intend on doing as long as possible. Invaluable for referring to when identifying that unit you saw on eBay.
