Coming out of the blackhole called work...retirement

Hello All

I have just retired and emerged from the mud of work that encompasses everything and acts light a blackhole for hobbies and enjoyment. Now that I am seeing some light I want to upgrade my 70's something stereo to something I can really enjoy. I read in a post from long ago about a preamplifier called a George Lightspeed. It was Australian, quality sound according to the posts and cheap. Is this something I want to consider or must I look at products in the thousands or 10's of?
