Although not an expert, let me attempt to summarize my perception of consensus view mixed with my own experiences...
Push-Pull is far more common, easier to implement than single-ended(aka S.E.T.), because you don't need super-efficient speakers.
Many folks go "toe in the water" by using a solid state power amp with a tube preamp. This makes sense for many because the smaller tubes in preamps are cheaper, last long, don't need to be biased, and often commonly found. For example 6922 & 6DJ8 are differnet names for compatible tubes that are common in preamps.
Power amps aren't difficult to bias, but it needs to be done. Some amps like BAT do it automatically. Most require the turn of a screw while a wire or clip is connected to a jack or slot or some type on the amp. You get a common meter from a Radio Shack type store, and turn the set screw while watching the needle on the meter. When in the proper range, you're done. With many amps, once a year or so it all you need(total 15 minutes). Others need monthly adjustment.
Tubes wear out slowly, not suddenly. They usually don't stop one day. It's like dust on your computer monitor...at some point you realize it's time to clean it.
All in all, it's worth it, unless you tend to go for low sensitivity speakers. Those requiring very high power & current will need big tube monoblocks that will cost quite a bit.
I've sold Spectral amps to go back to tubes, they just sound more like music to me. If you can live with 50-60 watt amp, there a plenty of fine choices. If you want SET, someone else is going to have to guide you, as I haven't lived through that one yet...Cheers, Spencer
