The new phono stage that I am working on right now would likely be a hybrid design. The highest gain portions of the design will be achieved with all SS components. I do believe that the final stage(s) should use tubes however.
The goal is a high-gain, flexible, QUIET and very musical phono stage for $2K-$3K with external supply.
To be clear, the PH 150 stands alone, but this design would offer the same amount of gain and similar flexibility of loading and other adjustments. It will be quiet and very musical, all at a price that is much more affordable.
