Balanced audiophile tube phono stage

Audiophile tube warmth

The Tube Box S3 B is a audiophile phono preamplifier that brings true analog warmth to your vinyl playback. It features a fully symmetrical and discrete gain stage, balanced 5-pin mini XLR input, and balanced XLR outputs. Adjust settings easily from the front panel, and enjoy clean, interference-free performance thanks to its robust aluminium chassis. Available in silver or black and made in Europe, the Tube Box S3 B is a compact yet powerful upgrade for any serious vinyl setup.

"B" stands for balanced

The symmetrical design is the real standout feature! Connect your turntable with the 5-pin mini XLR cable & profit of the balanced signal path. Symmetrical, or also called balanced, transmissions consist of a hot and a cold (also called + and -) signal. Both signal chains effectively carry the same musical information. A true balanced gain stage can now extract the final musical information out of the +/- signals and subtract, remove, all noise that could potentially be added along the transmission. As there are two separate signal chains, we also needed two individual amplifier sections. Definitely unseen in this price range & the best and cleanest amplifier for your phono signal!

Best Wine Opener ever
I hoped I made a wise choice to buy this wine opener and boy did I make the right choice. I have had 2 other electric openers and this is by far the best. You place it on the bottle and press the button once. You hold the bottle and opener and the opener does its job, you don't need to hold the button down. Once it pulls the cork turn it up side down and place it on the counter. It automatically stops and then automatically reverses and ejects the cork. You dinner guests will love watching it. Great opener!!!!!!

Excellent Buy!
I love this little beauty! Works like a charm, and is slightly smaller than its competitors, so it’s easier for packing and portability. I’m a flight attendant, so I actually use this on the plane to open bottles in premium class. It’s sharp looking too…and the attached foil cutter is well designed.
