Can't speak to commercial designs particularly, but my home brew dc coupled (as in -3db @ 1hz, reduced to unity gain @ 0hz - given that I've smoked a couple woofers in the past with it as is due to offset or motorboating problems upstream, I've never had much desire to run it flat to DC) high damping factor (>100) balanced triode OTL has been my hands down reference for the last seventeen years now. Not expensive at all to maintain, either ...after all, there's hardly anything in the signal path but tubes and resistors. I still have half or more of the original tubes in it - even at the output stage - I just can't bring myself to replace some of the oldest 6AS7G's, even though their emission has surely dropped somewhat by now.
