Another strong recommendation would be the Keces Ephono & Epower supply for $699. Mine is about three months old, and is awesome for the money. I have had two AVA phono preamps. Prior to the Keces, I had a separate AVA paired to my Benchmark LA4. The Benchmark replaced a AVA T10 RB with a phono preamp.
Along with external adjustments, it also is two separate chassis.
It did not take all of the 14 day trial period to decide which one to keep. The AVA is a garden hose compared to the Keces fire hydrant.
The attack, and decay, of acoustic instruments, is palpable.
