What should I do?

I think that you would be better off with a Premier 16LS. It may cost a bit more than the 17LS, but it is the better preamp. You would do well with the Calypso as well.

Jack, I think that the 16LS is a better sounding preamp than the 17LS, but I don't know about the 17LS2. The 16LS had a lot of the ART technology in it's construction. I have read that the upgrades from the 17LS to the 17LS2 are like night and day and the LS2 is far superior. However, I wasn't insinuating that any of these preamps were unacceptable. They are all excellent and in all likelihood you will be very happy with the sonics of any of them. I hope that if I ever reach your age that I will still enjoy my music.
