Has anyone used a Vidar in BTL mode (400W at 8 ohms) ?
Documentation limits its use to speakers only 8 ohms (and above I guess).
However, since the impedance of even an 8 ohm speaker can WILDLY vary and go even down to 2 or 1 ohms in extreme cases, does this cause any damage to the amp if used continuously ? The amp is supposed to have thermal shutdown so I presume it would not be damaged but has anyone ACTUALLY used it extensively in this mode ?
The idea is for about $1500 (two Vidars), one can get a 2 x 400 W amplifier. It is an incredibly sweet deal.

Assuming their website advertising is correct, Vidars are rated for maximum 200W/8 ohm and 400W/4 ohm loads. You can't just dial up more 8 ohm power without increasing the size (voltage and current) of the power supply and the amplifier together, or using two amplifiers for each channel in a bridged mode.
Amp. power ratings though, are supposed to allow for anything other than stupidly low speaker impedance excursions, otherwise manufacturers in general, would be flooded with warranty claims. https://www.schiit.com/products/vidar

Oops, I've misread the ad. thinking it was a mono amp, like other Schiit models I checked out. Let me correct that to 100W/8 ohms and 200W/4 ohms, doubling the power to 400W as you say, in bridge. It's nice I guess, to a have a beefy 600VA transformer too - that should hold up the power but there 's always a bit more risk involved - Maybe it's fine though, depending on the output silicon - good find.

Ian, you need only two Vidars to get 2 x 400 watts. EACH vidar in itself is a stereo amp which in bridged mode provides 400 watts mono PER ONE VİDAR.
