Quite honestly, it makes things sound better. It can be used as a stand alone preamplifier (not a phono stage). With 19.1 dB of gain it has more output potential than most preamps built. Simply plug you source into the SE560 and from there to your amplifier. It can fill the role of a turntable-cartridge only improvement in your system. From your phono pre (or directly from your turntable if it has a phono pre built in) to the SE560 then to your preamp or power amp. It also can act as a whole system enhancer by plugging your preamp into the SE560 then to your amplifier." - Bellari 🔑KEY FEATURES gain: 19.1 dB gain @ 1kHz input Impedance: 1k output impedance: 100 ohms RCA frequency response: 3Hz to 31kHz THD: .003% @ 1KHz S/N Ratio: >100 dB unweighted dimensions: 5.5"w x 3.5"d x 1.25"h / 140 x 89 x 32mm weight: .8 lbs / 362g 📦COMES WITH power supply
