Negative Positive
Title: Reliability/Quality Control issues
Review: The first unit I received made a constant rumbling sound, even with no input signal applied. The seller (Electronics Expo LLC) replaced this unit promptly. The new unit arrived and went into use. Six months later the PSW111 failed, and now does not power up. The protective fuse is blown, indicating internal component failure. Although I am satisified with how this unit sounds, I am alarmed by the rate of defects.
