I am not aware of any preamplifier with adjustable input and output impedance. Not saying no such device exists, just that I've never heard of one. Other than that, the new Esoteric preamps (C-03x and C-02) may satisfy your other requirements (the gain of each input can be adjusted +/- 18 dB), except that they use sealed sub-chambers for the internal power supply rather than a separate power supply box. But be prepared to pay large!
Preamp: adjustable impedance + GAIN
I am looking for a preamp which must meet the following requirements:
- solid state,
- fully balanced,
- Two sets of main output XLR and RCA, (adjustable output gain is more preferable)
- adjustable input and output impedance,
- separated power supply,
- airy, dynamic, musical, big soundstage, transparent, emotive vocal.
Please advice me.
Thank you so much!
