Testimonial

This is simple electronics that just works and occupies a small unobtrusive box ... uh called "BOX." Just plug and play insertion of the RCA cables from my turntable into the input and from the box outputs to the input of my amplifier. No earth loop issues and no need for the fairly well written small manual.

I’m new to vinyl, and got a turntable and some albums before I knew about preamps. So while doing research I came across this one, and it’s a great value for its cost. I don’t claim to be an audiophile, but, I can tell you, to me, my records sound great and I am enjoying this format thanks to this preamp.

I am tempted to explain here why a phono pre-amp is so important but without putting all that detail, the output signal can be very prone to noise. Even with a dedicated home theater type receiver, you may think that your phono input signal is appropriate but often will still benefit from a phono pre-amp that is more targeted to handling that phono signal. I was very pleased by this preamp, and even impressed by the headphone capabilities, going direct from phono to headphones.
