Very satisfied! I bought the PA115 to my turntable (a Technics SL-BD3) wanted to connect to my Soundbar and Suubwoofer my TV because I do not have larger systems with amplifiers and phono input and at the moment also wanted not to buy myself. Well what can I say ... come today, unpacked, connected and functioning properly. Sound is good, the part is very compact. Hum at high volume may not exist for me, but I did bolted the ground lead of the turntable with one of the screws on the side of the amplifier. Understand there not complaints. Perhaps it is partly due to the players of the people who have problems. Anyway, I can only recommend the thing, I also saved by Amazon also 13Euro.
