Review on Nobsound T12 Phono Preamp: turntable preamplifier, headphone amplifier for MM & MC with built-in RIAA by Victor Ewing

UPDATE: Been working 3 months now when I turn it on I get horrible feedback on my stereo (loud buzzing). I've checked grounding, tried multiple outlets, etc. Nothing seems to help. Worked great initially but is now outside my return window. will buy more expensive and reliable. Original post: Super easy. Connected and tried. Works as advertised. I once heard a loud hum when listening to a recording at about 90% volume on the unit (it suddenly started about halfway through), but turning the volume on and off and lowering the volume knob fixed the problem a bit, and it hasn't returned since then. For $35 I have no complaints.
