hk570i has more output power than harman/kardon wrote. I measured one channel with 8 ohm resistor ladder, RMS voltmeter, oscilloscope, 1kHz signal from sound card and got 66W at circa 2% THD - it started cutting sine wave above this value. This receiver might be reliable but in my hands it doesn't fully.
Choosing between Harman Kardon and JBL requires considering factors such as sound quality, design, affordability, purpose, and personal preference. To decide, consider if you want clear and accurate sound (Harman Kardon) or powerful bass (JBL), a sleek and sophisticated look (Harman Kardon) or durable versatility (JBL), an affordable option
The BMW 3-Series Harman Kardon system employs Logic7 surround software with a full equalizer, internal hard drive, and even Spotify built in to get the most out of the 16-speaker, 464-watt system with two bass speakers under the front seats.
