sound like a typical tube product - i.e. thick & textured, focusing more midrange than frequency extension?This was the "typical" tube sound of the 1980s .not at all of today's top-perfoming tube products.
And no, the Lampi B6 has extension and clarity in the top octaves that is quite impressive .qualities that I have heard many SS DACs not come close to matching. As for the bass, there is plenty of presence and weight in the bass without the "need" for blaring bottom octave output.
