It is an audiophile grade high-performance low-cost I/V stage board.
Different from traditional OP amplifier I/V solutions, the Transformer I/V plays music very natural and analog and the sound signature is enjoyed by many audiophiles.
It's fully finished/assembled with customized high quality audio I/V transformers included.
Features and Specifications
