Innovative miniature sized phono preamplifier with tube output and high end sound!

Tube Box S2 is our very first product to feature a fully discreet circuit design without using any operational amplifiers (OpAmps). It also is the first product to come with replaceable tubes for tube rolling and sound-shaping. This gives the customer many options to pick from and alter the sound signature to his preference. Tube Box S2 will give a full and relaxed laid back sound with lush mids, just like you would expect it from a much bigger high end tube phono pre-amplifier. It offers support for both MM and MC cartridges and comes with many gain settings to be switched on the front panel. Five variable input impedance settings are available to adjust to any MM cartridge, the 47k ohm input impedance setting is fixed and suited for high output MC cartridges. The aluminium/metal casing is adapted to our DS2 line in looks and protects against vibrations and electromagnetic interferences for superior sound.

A true high end solution in a much smaller package!

Great product!
Color: Black
I love this sponge holder. It is great for organizing my sponge and soaps. The steadiness is very strong. It is metal and has a drain at the bottom that you could pull out and clean. The appearance is nice. It is small enough to fit perfectly on the edge of your sink right next to the faucet. It is definitely worth the money.

Nice to keep things organized
Color: Black
My sink area is tight. And I don't like when thing look messy, this helps things look organized. The only thing is I wish it had suction cups to stay in place. Outside of that it's a good product.

Drip pan works great!
Color: Black, Color: Black
I like everything to have a place. This little sink organizer does not disappoint. It’s perfect for a small apartment where space is limited. The little drip pan works great preventing water from accumulating and stinking.
