The S-200 Signature is a versatile tube stereo power amplifier from VTL, sharing the MB-series' selectable tetrode and triode operating modes within a two-channel format. The S-200 Signature brings VTL's most storied engineering heritage to dedicated stereo power amplification.
Key specs that matter
Input sensitivity is 700mV, with input impedance at 45,000 ohms on both connections. Output power is 200W in tetrode mode or 100W in triode mode - a distinctive selectable configuration. Signal-to-noise ratio is an exceptional 110dB. Maximum power consumption is a substantial 1,000W. At 470 x 457 x 230mm and 54kg, the S-200 Signature shares the MB-series' chassis dimensions within a substantial two-channel commitment.
Sound and use context
Expect the warm, richly textured character tube amplification is broadly celebrated for, with the distinctive tetrode/triode selectability offering the listener a choice between greater power and a more characterful triode signature.
Pairing
VTL's own preamplifier catalogue, including the TL5.5 Series II, offers natural, brand-coherent pairings for a coherently voiced, entirely VTL-based system.
Alternatives
VTL's own ST-150 offers a related stereo power amplifier alternative within the same broader catalogue.
