Looking at your present set up and listening preference(%75 analog,%25 digital) without knowing what cartridge you have on the VPI Jr, my advice is try to upgrade the VPI JR and/or a high quality MC cartridge (if you don't already have one),the result may be better than upgrade to more expensive preamp. If you upgrade to a higher quality preamp now, you still need to improve your analog front end later to take advantage of your outstanding speakers and the rest of your source components.
Upgrade turntable or preamp next?
I just bought the Vandersteen 3A sigs and the Bel Canto Evo 2 amp. I already have a Conrad Johnson PV 12 preamp with phono stage which I bought new in 1997 and a VPI HW 19 Jr turntable which I bought new the same year. I play lots of records, but also listen to cds at home about 25% of the time. I've been thinking about either buying a Supratek preamp next or getting a better turntable in the 3,000-4,000 dollar range. Which do you think would have the most positive effect on the system? In other words, which is my weakest link? Thanks for your help.
