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.\u003c\/span\u003e\u003c\/p\u003e\n \u003ch2 data-mce-fragment=\"1\"\u003e\u003cstrong\u003eBeautiful mid-range \u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003eThe Tube Box S2’s sonic presentation is full \u0026amp; relaxed with a blossoming mid-range more typical of much more expensive designs. The stage welcomes most MM \u0026amp; MC cartridges on the market with a wide range of gain, loading \u0026amp; capacitance settings. The S2 series’ 2-layer aluminum\/steel enclosure shields the circuitry from vibration and electromagnetic interference for more music, less noise.\u003c\/span\u003e\u003c\/p\u003e\n \u003ch3
