Amazing Tube Based Phono Pre-Amp
Exceptional sounding. Tight accurate fast base & larger soundstage than my internal phono stage of the LP60 AT Turntable. It transformed the sound, corrected the center imaging well & just brought out a complete slightly more warmer sound. Equally detailed and warm at the same time. Exceptional device for someone who wants to try tube based pre amps for the first time for their vinyl player.

Excellent
Bought this after lots of research. Decided to buy after watching YouTube video of cheapaudioman. Are perfect phono preamp for enhancing sound of vinyl records. Highly satisfied with the product. My vinyls sound extremely good. Happy with the selecter switch. Can choose the sound output suitable for my ear. Also highly recommended for vinyl lovers who cannot afford high end phono preamp. This one does a perfect job. My amplifier and vinyl player has inbuilt phono preamp. This one exceeded my expectations.

Great little piece of equipment
I was using an ART Pre DJ preamp foe a few years and just bought this for fun as the fosi preamp has had some great reviews. Great build quality though the tubes need a bit of care and effort to place them properly. This preamp has been a revelation in all senses. Played some of the best sounding LPs in my collection, Alan Parson iRobot MFSL and few other steely dan albums. The low end has improved significantly, great mid range and normal highs. Might try out new tubes at some point but totally satisfied currently.

excellent pre-amp for MM turntable
I own marantz receiver with fluance TT. when i connected TT to phono input of the receiver the performance was good but low frequency was not as expected. After connecting this pre amp output to the aux of receiver(not to phono input) has shown excellent performance with very good amplification at all frequency ranges. A perfect preamp for turntables

Nice product
I found the preamp nice even though I have just used it for about one hour. It has yet to be broken in. You get a tube signature sound in your solid state setup. I am presently using it as a aux preamp and have not tested it for phono.Good value for money.
