Joe restored my Sansui G-8000 and the work is phenomenal. Dead quiet, powerful, and looks incredible. He’s in high demand for a reason, so you need a bit of patience, but the price is fair and the results are absolutely worth it.

Great service, our Harman/Kardon amp works perfectly, and Joe was pleasant to chat with. Was recommended their work through Record Collectors Paradise and I would do the same.

Excellent option for getting your vintage stereo equipment repaired or refurbished. Joseph's prices are reasonable, and he'll be honest about what's needed. He's often busy so don't expect a quick turnaround.

If you’re looking to get your vintage equipment repaired, Joseph is the best out there. He was able to bring my Kenwood amp back to life and make it sing again. It sounds superb now! He’s extremely knowledgeable and passionate about his craft.

I would recommend Joe at Sigma anytime, he has done work for me and in a timely manner, he takes care in evaluating the work that needs to be done and is very professional about it. I have recommended several people to him with all being satisfied with what was quoted and done to there stereo components, as well. Joe is easy to talk to and an all around good person. If you need work done in a professional and timely manner I recommend Joe at Sigma. 😀
