I think they are phono pre amps that I am asking about..
you hook up your turntable to this phono pre amp if your receiver doesn't have a phono input.. are they like DAC's, usually better sounding than most built in phono amps in receivers?
I am asking, since I think i'll be keeping around one or two turntables I got for cheap.. and I want them to sound their best and take it to the next level without buying a new turntable. Phono pre amps seem pretty reasonably priced from what I can tell if you just need a no frills one.
I see NAD, Parasound and Cambridge or Creek Audio make em for not much dinero.
