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!

Nice big tire toy
Size: Large 10", Style: Rubber Dog Toy
Our dog has had a tire toy about the same size as this one for 2 years, but it's finally been worn down from his love and zest for it along with weather. When I saw this one, I got excited! Great size for our 80lb 3yo pittie and pretty tough too, although, it's beginning to show signs of wear in only 3 weeks of him playing with it. It's not nearly as rugged as his old rubber tire. We'll have to see how long it actually lasts before I say the price was worth it or not.

Great dog toy for large breeds!
Size: Large 10", Style: Rubber Dog Toy, Size: Large 10", Style: Rubber Dog Toy
My dog Judge is a 110-pound German Shepherd that loves this tire! It is not the traditional ball that dogs like to play with, but it is so much safer since larger breeds might choke on a ball, as it’s easier to swallow! Judge doesn't go anywhere without his tire! From an owner's standpoint, it’s great also since it’s easy to throw and roll as well as last longer than most toys since it’s made of thick rubber! Best toy for the money I have found by far! Judge has the size large 10”!
