We'll lead with it because it's the conversation starter every time someone listens to this amplifier for the first time. The S6 grips speakers with a control you don't expect from a pure tube integrated. When we ran it with our Aurai Z165 speakers, they played deep into the 30Hz range with speed and authority that should not be possible from a tube amplifier at this power level. This is no-joke, solid-state-like bass control in a tube amplifier chassis.\u003c\/p\u003e\n\u003cp\u003eThe midrange is everything the EL34 is famous for: dimensional, layered, presence. Guitars and vocals have an intimacy that draws you in. On difficult recordings from the 1980s — the kind that expose midrange hardness immediately — the S6 is relaxed and honest. Nothing artificial is happening.\u003c\/p\u003e\n\u003cp\u003eThe highs extend naturally and smoothly without any sense of roll-off. The S6 does not sacrifice the top end to protect the midrange.\u003c\/p\u003e\n\u003ch2\u003eThe Construction\u003c\/h2\u003e\n\u003cp\u003eEL34 output tubes, point-to-point wiring throughout, zero global negative feedback.
