Great customer service. I have a four channel amp sound outstanding (SDS-470). Not GaN. Initially had an issue with one of the four channels out, returned, got a beefed up power supply 800VA torroid and 60,000 uF power supply. No issues since (3 years?), quality product.
Looking forward to trying the new amps from this US company.
