Paul, For less that 1K you can pick up a EAR 834L. This is a very basic, simple to operate, preamp using 3 tubes which have very very long life (5yrs at 24/7 +/-). Tonally it is much like your Tylers - smooth and musical, but not dull and boring. It is voiced very much like my ARC SP10II. I have used one in a secord system for about 5 years with zero problems. Tube rolling with this is cheap and easy, assuming you want to fiddle with the tubes.
