Among the enhancements to VTL's new top-of-the-range mono amplifiers, the Siegfried IIs ($65,000/pair), is a completely revised signal path and fully balanced negative feedback loop that uses no global negative feedback. The power output remains 650 watts in tetrode, 330 in triode. "It's the same platform and same tubes," Luke Manley conveyed, ensuring that owners of earlier Siegfrieds can have their amps fully upgraded. Driving TAD Reference One speakers, the new Siegfrieds produced "Best of Show" sound.
