better late than never I guess....but the Z-PH20 has been available for sale now for a couple of months. Meant to add this here at the time of release, so goofed up here
Anyhow, this is a huge improvement over the Z-PH10. In hindsight, this improvement should have been done a long time ago. The main change is the addition of MOSFET output buffers, this will allow the Z-PH20 to be used with many different preamps, not just the PAS preamps we sell.
The RIAA stage has also been completely overhauled.
The result is an excellent MM preamp, this will put to shame many so called high end tube phono preamps out there!!
Anyway, enough marketing jargon.
