Opened up the sound
This perform better than the inbuilt phono stage of the turntable or the onkyo receiver. The voice is warm and pleasent. A good stylus with the phono preamp is a must if you have a turntable.

Works fine but power adapter not suited for UAE
This item does the job with my record player (Fluance RT85) however one little gripe is that the plus is not suitable for UAE/UK - it is a 2 pin plug. It is on the product page as an image (not text) but after some scrolling - would help if its in title description. Small gripe to an otherwise great product.

Très bon
Déjà le poids de l'appareil donne une impression de qualité, mais se confirme à l'utilisation, amplification réglable,son très bon, pas de souffle ou bourdonnement, parfait pour moi.

Polecam
Myślałem, że będzie troszkę większy, ale robi mega robotę a żarówki dodają tego smaczku do gramofonu. Polecam!

Too Good To Be True For The Price
This Preamplifier is amazingly good for the price and compares favourably when compared to my €1,500 Preamplifier. Appears too good to be true for the price, but it delivers clean smooth musical sound with zero gain noise.
