Review on π KooBook 1-Piece NE5532 Op Amp HiFi Preamplifier Signal Amplification Board - Bluetooth Pre-amp, DC 12V-35V by Peter Burkart
Major Disappointment - Poor Audio Quality
As a newcomer in the Home Audio world, I bought this product based on the high ratings it received. However, Electronics are definitely not its forte. As a result of my tests, I determined that the audio quality was terribly low and full of static. The only good thing about this preamplifier is its Bluetooth connectivity, which is easy to set up. Unfortunately, that doesn't make up for the overall poor performance. Would not recommend.
- Easy to use with Bluetooth connectivity
- Requires a DC12V - 35V power source, limiting its portability
