Re: Pre-amp for Golden ears
To combat microphony, your 'shock mount' needs to achieve good mechanical isolation across the entire bandwidth it is going to be subjected to. That makes it a big deal because then you have to make sure the primary suspension resonance is below the lowest frequency in the room.
A valve and its holder are quite light so the springing must be very soft.
Alternatively, add mass.
And you don't really need to isolate one preamp pard from each other so why not mount the whole preamp on some sort of suspension? Remote the switches using relays. Motorised pot?
Otherwise, join the dark side and use a few transistors.... they can do cascodes, too.
