Stellar right out of the box
The Tube Box S2 uses fully discrete circuitry, rather than operational amplifiers (aka Op-Amps, used in simpler, more affordable designs). The standard, user-replaceable tubes sound stellar out of the box, though the design opens the gates for sound-shaping via tube rolling should you want to take it a step further.
Beautiful mid-range
The Tube Box S2’s sonic presentation is full & relaxed with a blossoming mid-range more typical of much more expensive designs. The stage welcomes most MM & MC cartridges on the market with a wide range of gain, loading & capacitance settings. The S2 series’ 2-layer aluminum/steel enclosure shields the circuitry from vibration and electromagnetic interference for more music, less noise.
