Very nice and necessary gadget for magnetic TT

I have connected the Fosi Audio Phono Pre-amp to my Technics turntable and line out to my Sonodyne amplifier and speaker out to Philips HiFi-International 3 way speaker system. The line out audio signal is strong and produces hifidelity sound and it's bass and treble combination is truly fantastic. I find this pre-amp a must buy for all vinyl lovers to keep alive and enjoy the magical experience of listening to original hifidelity music since in today's time it is difficult to repair faulty phono lines of past amplifiers and also hard to get new amplifiers with phono line nowadays. We can convert any amplifier or home theatre system into a phono turntable compatible amplifier via this Fosi audio MM pre -amplifier
