Reference class phono preamplifier with unique continuously variable impedance control

This ultra low-noise and low-distortion preamplifier is truly made for the audio connoisseur. It offers not only breathtaking performance but is capable of adapting to virtually any phono cartridge through variable its impedance control. Impedance adjustment can even be done during playback! Due to the use of premium components, such as the SSM2019 from Analog Devices for the input stages and the Linear Technology LT1010 as its high current buffer stage, Phono Box RS delivers ultra low levels of distortion and noise. Its very low output impedance makes it insensitive to selection of interconnect cables and lengths.

A selector switch permits use of fully passive RIAA or DECCA equalisation. The Phono Box RS offers fully balanced circuitry and both XLR and RCA inputs and outputs. Vinyl playback has never sounded clearer, more detailed and smoother than with this superlative phono stage!

Great Replacement
The good. A perfect fit for my left turn signal lamp. 2003 BMW 330XI. Works and looks good. Has weather seal. We will see how it stands up to the Florida rain and car washes. The bad: As you can see in the picture the right lens retainer clip came in broken, Probably damaged in shipping. No big deal I just needed the left, I'll probably just super glue it and store it as a spare. Overall I got my moneys worth and I'm happy. Product was as described and arrived on time. I will buy from this seller again.
