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!

Measurements just didn't add up.
Size: X-Large, Color: Sky Blue
Quality of the shirt was nice but the measurements did not add up. I wear a 17 1/2 neck and 36/37 or 37/38 sleeve. I ordered an XL and the sleeves were a little to short and the neck was way to big. Could never wear a tie with this shirt. So going up in size wasn't an option because of the neck. The next size up that had longer sleeves was a 3X, not happening. So if I went down in size the sleeves still would have been to short and the shirt would have been to tight. If the shirt fits you then you have a good shirt at a great price with lots of colors.

Nice shirt. Wrinkles alot.
Size: 4X-Large Big, Color: Light Grey Vertical Stripe
Like the style and construction of the shirt. Fit and finish are as expected. Unfortunately the fabric wrinkles easily. Definitely requires ironing. Wish this shirt was a wash and wear but it's definitely a wash and iron before wearing shirt. Otherwise I have no complaints. Fabric is lightweight and could be used in summer as a dress shirt.
