ka-pow, version 4

My VSi60 exploded too, twice now. Once at home, then once back at the shop AFTER they had replaced the tubes and protective resistor. I also saw the floor sample VSi60 have an explosion before I bought mine. That makes four explosions, including Stereophile's review sample.
The amp sounds great, but I'll be considering solid state next time.

Power rating

"The amplifier exceeds that specification from the 8 ohm tap into 8 ohms, with 53Wpc available (17.25dBW) at 1% THD, though only 44W (13.4dBW) were available from the 4 ohm tap into 4 ohms at 1% THD."

13.4dBW is 22 Watts not 44W.

This amp sounds great, what a shame it is prone to self destruction :-)

My dBW ratings follow the convention established by Martin Colloms and the late Peter W. Mitchell in the 1980s: they are referred to 2.83V (1W into 8 ohms). Thus 44W into 8 ohms is is 16.4dBW, 44W into 4 ohms is 13.4dBW. An amplifier that behaves as a perfect voltage source (the ideal) thus offers the same dBW rating into all loads, an easy paradigm to grasp.
