Model no:   BUF-003
   

  

All tube buffer amplifier with RCA-balance converter

This is our basic model of a unity-gain balanced input to RCA output buffer amplifier. This amp can convert any RCA input into a balanced XLR input.

If you have a balanced output CD player, and an RCA input pre-amp, then you can add one of these units with a short RCA cable (less than 1ft). Connect from the BUF-003 output to your pre-amp input, and then you can use an XLR cable to connect the CD balanced output to the BUF-003 balanced input. By using this type of configuration, you can convert your pre-amp input into a balanced input, which will greatly improve the dynamics, focus, depth of sound stage, and openness. This conversion method can also be applied to pre and power amp connections. If you have a balanced output pre and want to convert your RCA input power amp into balanced input, simply add a BUF-003, then your power amplifier will become a truly balanced input power amplifier.
