Hello to you. How big is the difference between phono pre amps actually ? Between them as standalone and standalone vs inbuilt. To be honest I cannot hear a big difference in sound between my inbuilt phono and Pro Ject Box MKII and if any, then both sound as good. Are 200 pound phono amps worth the price ? I think the phono amps should be definitely loud enough. It is pretty hard to find any that have high gain...above 40dB for MM. Usually they sound so quiteter than CDs. So how's about the sound according to you ?
