Ditto...5k intergrated should have an excellent phono preamp...if anything the Rega 1 is probably the weak link."
Just in case I wasn't clear in my first post, that's the point I was trying to make. Don't limit an upgrade to just a phono preamp. Something else, such as a new cartridge, may be a better option.
