What amplifier is going to mated with this preamp? Impedance matching is key.
For example, the Juicy Music Blueberry has a 3.5 kOhm output impedance. It
must be mated with an amplifier having high input impedance.
Be certain to check the output impedances of all the preamps you consider, and
check that they will properly match with your amplifier. If you have a tube amp,
then your possibilities are pretty wide open. If your amp is SS, then you need to
be very careful with matching.
