Hi Shake ;~)
First of all, did you mean your speakers are 16 feet away from your listening position (not 16 feet apart, which is pretty wide apart?)
If you like tubes, then the best place to reap their benefit(s) is in a device that actually amplifies the signal. That would be amplifiers (obviously;~), phonoamps, and microphone amps. Preamplifiers are basically source selectors and volume/balance controllers. They don't really do any 'amplifying'. What we want in a preamp is QUIET! Before a signal gets to the main amplifier, having tubes in the signal path only adds "tube hiss" and who needs that? We do put up with a little tube hiss from phonoamps b/c you get great phono amplification (bang for the buck) with tubes. Not to say there aren't some really great ss phonoamps, but they all start at ten times the price of a similarly great sounding tube phonoamp -- of course you don't play vinyl, so none of that concerns you -- but I'm just saying ;~)
If you want a great sounding system starting from where you are now, you should think about a nice pair of tube monblocks for your Tylers. I think the Woodmeres are fairly efficient (the website no longer lists the specs for them) so you wouldn't need a super powerful amp; but more important, if you want to use tubes to enjoy the quality of all the Woodmeres' Scan-Speak drivers, both bass and mids, then you want to preserve all the damping ability that a tube amp can muster -- which means keeping speaker cables as short as possible. Thus the recommendation for monoblocks. If you use a ss amp like your Coda, especially with efficient speakers, it could practically be in the garage as long as the speaker cables' conductors are big enough (10AWG). But tube amplification would really be delicious with those speakers. And some day, if you want to bi-amp them, and get a couple of modest ss amps just for the woofers, you'd be way ahead (sonically) for the money, than you would be just throwing a sub into the current mix (even though Tyler makes some nice subs ;~)
