I'm doing just that and with great success (IMHO). In my case I'm using a vintage Sony preamp (TA-e77es) as a phono preamp as it offers gain for both MM and MC cartridges with two loading choices for the latter. It is virtually noise and distortion free and drives a Sony receiver with line in and the preamp out driving a SS or tube amp of my choice. So much flexibility and despite what purists might suggest, no noticeable distortion even with all of the electronics in the path. The receiver amp and speakers are not in the path and it will not, as suggested by others, be harmed by this arrangement. Go for it and see how it sounds to you!
