I am looking for a stop gap active preamplifier to drive a Sugden Masterclass amp. I hope eventually to find a used Sugden Masterclass pre-amp however they are thin on the ground. The only pre-amp I have to hand is a Quad 34 which is a poor technical match as the output voltage is too low as well as being rather sonically restrained.
The matching Sugden LA-4 pre-amp has the following specs so something with similar specs would be ideal.
- Input impedance: 50k ohms (single-ended), 25k ohms (balanced).
- Output impedance: 600 ohms (single-ended, balanced).
- Input sensitivity: 100mV for 1V output.
I only need two inputs and balanced operation would be great but not essential.
Budget is under £500 (preferably well under) and needs to be something that can be moved on quickly when the time comes. So I am looking for something that is reasonably well known and not too quirky. Look forward to seeing what is out there :-)
