Hello, I just got the JH Audio JH-3A Amp for my JH16 and find the sound quality to be not very good and the volume is lower than connecting the JH16 directly to the iPhone.
I also tried the USB connection to use it directly with a Mac Laptop and had the same results. The JH16 directly connected to the Mac produce better sound and more volume than the JH16 / JH-3A combination which distorts after turning the volume up.
Anyone having the same issues? What is the preferred cable / method to connect the iPhone to the JH-3A?
