Not available until Q2 2021 - consider the Tube Box S or the Tube Box DS2
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!

Orders for items not in stock
Given the vast amount of variations of each product (e.g. AudioQuest cables) or Pro-Ject Audio Turntables - we keep the most common options in stock (i.e. gloss black finish, or 1.5m RCA cables) whereas longer cables or cables with terminations that are less frequently ordered will be ordered as required.
Generally speaking - we receive orders within 2-3 days for UK suppliers and 3-4 days for European suppliers (i.e. AudioQuest, DALI).
We want you to be 100% satisfied which is why we'll give you an email/call if item(s) aren't in stock and give you the option of changing the order, cancelling or if you're happy to wait a few days, we'll get it out as soon as possible.
