Simplistic NJFET RIAA

When I bought my setup I was leaning towards the 10x5 as my father has one and the sound is awesome, but the dealer, a very knowledgeable character Told me that with my current setup (brio r integrated amp, rega rs3 speakers) I would be better with the goldring. The big step in sq would come with an upper in the line dynavector like the d17 or the d20 but I would need a better phono stage and whatnot. I'll be improving the phono soon to bipass the internal phono stage in the brio, which should add something to the picture.
