What am I doing???

I am sure its somewhat common that as someone needs different things from their system the system itself needs to change.

So let me tell you a bit about my system. NAD T742 with PSB Image T55 towers, B15 Monitors and C40 center. Using an oppo dv-981hd as my main source. I think its a budget minded but not bad system....

Well now I want to move to vinyl, and of course the t742 doesnt have a phono in. So I have been looking for a nice phono stage. I am getting quite confused now, I kind of like the idea of going with tubes, but then I read reviews for the onkyo a-9555 and wonder if it makes sense to just go with that?

Could I just use the onkyo and sell the nad? Is it better to go with something like the pro-ject phono stage? I was considering a Conrad-Johnson EF-1 Phono Preamplifier.

I would like to have the ability to build up my system piece by piece so part of me things that a seperate preamp even if it is a bit nicer than necessary is a good investment in the longer term.

Also vinyl wise listening to lots of Beatles, U2, and some indie pop-punk type of stuff oh and the Ramones. TT is a technics sl 1210 mk2 kab modded. Shure Hi Fi M97XE cartridge.

Hope that helps....any suggestion at all is welcome.
