Will SS mess with my tubes??

Neither. It will just change change it. Different phono stages will sound different for many reasons. Ultimately it will still pass thru the same line stage section of your reciever. Whether your reciever's line stage and your phono pre-amp mate well is probably only predictable by someone who knows the sound of your reciever's line stage and the replacement phono stage. Best to test drive the phono stage in your system if you can before you buy.

Irichal, Lets assume that you have a modest TT set up with a MM stylus. If that is so then a modest SS phono pre-amp is an excellent idea. They are simple and usually quiet. And you stand a reasonable chance of improving the phono stage you have on your reciever. I'm not experienced with budget SS MM phono stages but they abound. Sorry I couldn't help more. But if you have more than modest stuff and have the appropriate budget clue us in on the equipment, type of cartridge, and your budget.
