"If silence is golden, The Tube was 24K pure gold..."

"The Tube Mk.II's reproduction of microdynamics was as good as it gets in my experience, regardless of technology"

"No solid-state preamp I've heard can match that sense of continuousness and flow..."

"So while The Tube Mk.II subtracted nothing critical from the sources feeding it that I could hear over a long audition period, it did add one thing I noticed: an extraordinarily high level of listening pleasure. "
M. Framer

"The fact is that for any "audio checklist" factor I can think of — quietness, dynamics, tonal accuracy, frequency

extension at both ends of the spectrum, spatial presentation, focus, and above all the ability to draw me deeply inside the music — The Tube Mk. 2 is simply the finest audio instrument I have reviewed"
