You should consider upgrading the 90X to the new 9000. I used a 90X for 3 years and was surprised by the difference that I heard when I switched to the 9000. Made me think the 90X was defective. Cleaner, quieter, more involving. Well worth the cost of a change. Set-up easy; same VTF, same loading, same anti-skating. Plays nice with the K&K phono with 38 ohm loading.
