I desperately need some recommendations for a high gain, low noise fet for a phono stage I'm pulling together.
Its made up of 2 linear gain stages, with passive eq. The gain stage topology is essentially a very simple triode type circuit. (Yep, you read that right). With just 1 device in each stage.
I'm trying to achieve extremely high MC gain (good enough for low o/p Ortofons, etc) and I'm just terrified about ensuring that in particular, the first stage is treated with the care it requires. (Hence my search for a high gain, low noise device).
I understand Toshiba fets have a decent sonic reputation . Any recommendations anyone? (Toshiba or anything else)

Fets
The Toshiba 2SK170 or 2SK389 (dual). The 2SK147 is even lower noise but not in production anymore. (nobody is getting any of my stash) For more info:
