The preamps recommended above IMO are average to below average in sound and build quality. You would be better off with an old Counterpoint SA-2000 if you don't need a phono ad an SA-3000 if you need a phono. They can be easily upgraded to close to reference quality. If you prefer a 6SN7 sound then the same foes for the DeHavilland preamps, the upgardes make this preamp also sound fantastic.
