I'm not much of a 'specification' guy, but in describing the speakers, the 1 thing which would help and was NOT listed was sensitivity / efficiency. Listing the wattage of a speaker is, in general, meaningless.
Now, if you want to integrate a 2ch / HT system, an integrated with HT bypass may be useful. Also, my PSAudio integrated, from the GCC series has a set of preamp outputs which could be used to feed a HT receiver w/2ch music. I use these outputs to feed a sub.
And as a matter of convenience / ease of use, you may want to avoid tubes, if as you say, you are 'in the middle of nowhere'......All you need is to have to solve a problem via the mail or over the phone. SS has the edge in overall UPTIME of gear. Yes, there are exceptions, but unless you are willing to learn lots about tubes and go thru the learning curve............
