Be aware that stereo amps that can be run bridge/mono will usually not be able to support speakers with lower impedance. The Schiit Vidar can be bridged mono, but it is only safe with an 8 ohm speaker in this mode. For 6 or 4 ohm speakers, the amp will likely over-run and shut itself down.
@mancub - I don't know that you will get any more value from this thread versus your last thread. The Emotiva amps are great for the money, but use cheap components. If you got the XPA-1 Gen 2, I would put Isoclean fuses in them to take the edge off the bright/harsh character. However, the XPA-1 will be fine running down to 3-4 ohms.
Is Parasound A21 not in your consideration?
Those Odyssey Stratos monoblocks look very nice! They do not have a trigger input, so you'll have to manually turn them on/off for listening.
