A very nerdy thing I’ve enjoyed doing is listening to the many different combinations of inexpensive phono preamps and cartridges presented on YouTube. Here is how the setup in my home office sounds. Listen quick, in case YouTube decides to yank it, despite many other unofficial copies of the song already being there.
The cartridge is a Grado Black ($75), the preamp a Behringer PP400 ($25), and the turntable is a Technics SL-BD20D. The Technics was the last of the P-Mount (T4P) models, and it was purchased new for $99 from J&R Music World, an outstanding retailer and mail-order service that is gone, but not forgotten.
