Hi, I purchased the P3 preamp and ZA3 power amp, but when I plugged everything in there was no sound coming out of the speakers. I contacted Fosi via their chat and they immediately took an interest in my problem. Following their verification advice, before returning the product, I identified the cause. Now the system sounds great. The music is rich in nuances and without any distortion. Excellent Hifi at a reasonable price. Highly recommended manufacturer/seller.

So glad I bought this amp! Hooked it up via Bluetooth to a pair B & W 601 speakers (circa 1998!) which had been languishing unused for the last seven years! The sound quality via the Fosi amp is great! I also have Sonos One paired up, and they do not compare to the sound I am getting out of the amp and old speakers. I purchased directly from their website and not via Amazon. This was much cheaper and customer service was excellent, with any queries answered promptly. The order was delivered to me within 9 days! If you have a good pair of passive speakers and want to use them again, go for Fosi!
