help me pick a phono preamp.

Edesilva, sorry you've had a bad experience, but just to balance the dialog over the Grado PH-1, another Audiogoner, "Dennisb," recently purchased the Grado Sonata 0.5mv cartridge and the PH-1 phono stage and he seems to be very pleased with the combination. I don't recall what line stage he's using, though.

Just a thought... Have you tried calling Grado and asking them about what you're experiencing? They've always been pretty good about talking directly to their customers who have questions.

"Rolling tubes" is to swap the tubes that came with the unit from the manufacturer with other tubes of different make or vintage (but that are still electrically equivalent). Swapping the tubes will change the sound; the obvious goal is to gain an improvement.
