Good work. What is the performance closest to a retail amp you are expecting or aiming for? what is your reference?

This is a DIY project , if things are well planned, it can leave commercial amps available in India far behind.

Quality will be best, when it comes to audio, things depends on individual perspective, ears and taste and media and place.. and .. lot of things apart from parts, PCB and PSU. out aim to pair the best available in market.

This pre-amp will provide adjustable input gain so one can select suitable gain depending on input source and amplifier. I have used good quality parts and low noise op-amp.
