history of Vector Research 7000

I have an old Vector research 7000 that I use as a tuner. I have it hooked up to a Musical Fidelity A5, an Opinion cd, and Sonus faber home edition speakers. I found it in the garbage and it pulls in stations better than my Denon DRA 335R. Has anyone ever heard of VR, as it is not listed on many websites and I am wondering if I would get better sound with a used Accuphase or McIntosh or something? I live just above NYC. By the way, I don't know much about this hobby now, but I knew even less when an old neighbor passed away and his daughter gave me his Kenwood KT(forgot the model). I thought it was waaaay too big so I tossed it after a few months. Laugh and the world laughs with you, cry and you cry alone. Alan
