I have just installed a Technics SL-QX300 old turntable with the Audio Technica ATU 4040 EP cartridge, and I am looking for a phono preamp. A friend suggested the Ifi Zen Phono, but my dealer told me to go for the Pro-Ject Audio Phono Box S2 Ultra which is better, if I can spread my budget. This costs 50% more than the Ifi.... Have anyone experience with any of these phono stages ? Is the Pro- ject worth the higher price ?
