I myself would perhaps audition the PS Audio GCPH for $995.00 They offer a 30 day in home trial with full money back (minus shipping) if not satisfied.
Looks to be a good solidly built unit, 4 loading selections on rear of unit, 4 gain settings, yet has an adjustable gain control on front, with also a phase, and mono button.
Seems with this unit, no matter what output your cartridge, you get a perfect voltage in to your pre-amp, and with the front gain control knob, you don't even really need a pre-amp. You can run this unit directly into an amplifier.
Tubes are great, and offer warmth, but that's perhaps provided you wish to run the gamut of rolling tubes, taking chances buying NOS tubes, the possibility of gettig burnt with tube hustlers, and in the end may eventually blow more on trying out tubes than what the unit itself cost.
If you can possibly find folks here that live close to you, and perhaps audition some units, that would be a great plus. Some places like Musicdirect, and possibly Elusive Disc will also offer trial periods with units, in that if you don't like them, you can return them for full refund, or exchange. Mark
