Review on Enhance Your Audio Experience with OREI DA51 Optical Fiber Coaxial DTS Digital-to-Analog Audio Decoder by David Sanchez

When I first plugged it in it worked as advertised and gave us great sound for about 15 minutes. Then, after about 15 minutes, it started making an annoying squeaking noise from just the center speaker. Swapping cables didn't help. When I turned off the input, only the scratching came through. If I unplugged the power or unplugged the center speaker's RCA plug, the noise would stop, so it must have come from the unit. I wrote to BomBay through this website explaining the problem but never received a reply. I called Revain, explained the problem and then had it sent back. I chose a similar product from another manufacturer.
