schiit vidar in btl mode

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 and overcurrent shutdown so I presume it would not be damaged but has anyone ACTUALLY used it extensively in this mode to write about their experience ?

The idea is for about $1500 (two Vidars), one can get a 2 x 400 W amplifier. It is an incredibly sweet deal.

@cakyol,

Buy a pair of Schiit TYR amps, and be done.

Tyrs are double the cost.

Tyrs are double the cost.

Yes! And its triple the amp compared to a Vidar. Example: 55 lbs. 12 lb choke. 160,000uf filter capacitance. 24 150W Toshiba output devices. 7 internal power supply rails, including HV boost rails that uses unique discrete CFP regulators. Sounds like overkill? It is. Tyr is our most insane amplifier ever, designed for driving difficult speakers without breaking a sweat.

Read through the FAQ's on the Vidar website.  Notice what they say about using a single amp into a 2 ohm speaker.  You can apply those same comments to a pair of bridged units, except now they apply to a 4 ohm speaker.
