Phono stage or pre Amp? which is most important.


Hi
I've just got back into vinyl after many years of digital music listening. Bought my myself a cheap turntable(Linn Basik, Akito arm, AT 95e Cartridge) and a project phonobox e phono stage. Just wondering how important the phono stage is compared to the amps it's going into. I know the project is only a £50 box so just wondering what next step up would be. My pre is a NAC 202 with NAPSC, Power is NAP 200, speakers CM6 s2. Is the Naim Stageline worth the money or is there a more budget friendly step up.
Cheers

The phono stage is the most important piece of line level electronics as it has to deal with a very low input voltage. Signal to noise ratio becomes more critical as accuracy of the RIAA reversal. In the context of the system you have the Project should be fine. If you decide you really like vinyl then I would upgrade the cartridge and phono stage at the same time. I am unfamiliar with the Naim. I like tube phono stages like Audio Research.  
I used that same Linn table/arm combo for years and never considered it "cheap". Don’t be the guy that "knows the cost of everything and the value of nothing". Regarding your question, a budget phono-pre can sound excellent so I'd go big on the main preamp for now and get a better phono-pre later.
As an ex-Naim person, the biggest improvement you can make to a Naim system is to upgrade the power supplies if possible.  I had a 202, but I don't recall if you can use a hi-cap with it.  If you can, pick one up and your whole system would be elevated.  IMO, the phono preamp is fine with your cartridge.
