Hi,
(1) If you need a 845 or 211 to power your speaker load, you will do better with a really good solid state audio amplifier, one that is of high quality.
(2) For someone asking such basic questions as cap versus transformer coupling, I would seriously caution you againt building amps with ultra high voltages for lowest distortion. ONE mistake with 1,000 to 1,100 VDC will likely kill you. It is very quick, permanent.
(3) A DC SE amp with 845s, low B+ is quite possible - 5 Watts output. Triode connect a 7788 and DC connect it to the grid of the 845. It will be more transparent, being a two stage, and will creme all the three stage amps out there, handily.
