Is there a cheap tube stage that you can insert between CD/pre and power/reciever? Does it actually do anything? Also are there any "vintage" sounding speakers out there, that are new? I mean warm/softer top end just sort of mellow sounding. I've been listening to lots of older stuff, the Beatles, The Who, and stuff and some of their recordings through an average/cheap stereo sounds sort of.....annoying, and thin and harsh. I want to construct a smaller setup specifically for pleasing sounds from older recordings, not so much about detail and super hifi clarity.
