As most of you know, my partner and I have been repairing, upgrading, modifying, rebuilding and manufacturing audio components for twenty plus years. He has a masters in electronic engineering. He is the guy who people turn to when their tach cannot fix something. So while I believe a few people here are good parts swappers, probably most cannot fix a hum, or noise, or change a design to make it sound better. We offer our services to everyone who needs them. Plus we enjoy meeting new people and assisting them the best we can. We have our dedicated Listening Room in Northern New Jersey so people can come by and learn, and enjoy listening to various components we have in our room.
Happy DIYing!
