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.

"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.
