Tubes or stick with S/S

I've never seen a tube driven sub, so an all tube pre/amp system (as I have) with one or two (or a swarm) of solid state amp driven subs seems fairly normal, and using 2 RELs with the mains left alone works for me. The tube amp I use is a 12wpc or so single ended thing, and the subs total 250 watts...sounds sublime.

I follow Had's stuff on Ebay as one of my "saved sellers" (in fact the only one of those), and if I actually felt the need for another Had amp I'd buy that 300B version immediately (I wonder why his amps don't sell in the first hour of listing 'em)...still, "almost" unobtanium  seems accurate when a very well regarded amp designer manages a couple of dozen Ebay only amps a year, likely because of commitments to build the Inspire headphone amp for Moon as well as the previously mentioned mono amps...by the way the mono amps are 25 watts each and at 4 grand a pair seem to represent a serious bargain in this Kondo Ongaku $95,000 world. Buy a Had amp pair and save over 90,000 bucks...money to bribe the kid into college, get that Porsche Cayman, buy your own massage parlor...endless possibilities...

Note that Dennis Had's amps are almost unobtainium and I found mine, a late 2016 sep ("p" for pentode), simply from a lucky Ebay score. You can buy the mono blocks from Moon Audio but they're pricey although likely worth it. My little Firebottle version is 12wpc or something (depending on the tubes you stick in it) and drives Klipsch Herersy IIIs with gusto. A Steampunk tone monster that has astonished me from day one. I'm also a mechanical watch freak...latest faves are an Oris Divers '65 with the distorted deco-ish numbers, and a Ball Trainmaster Power Reserve (tritium glow tubes...who doesn't like those?)...another hobby that exactly zero of my friends care about. 

Tubes are simply more interesting as you can swap 'em out (you eventually have to do that anyway, so that part of "interesting" is built in) to adjust tonal preferences, they look cool...my 7581a tubes have that blue glow fluorescence, their linearity and harmonic "musicality" are what solid state stuff often claims to resemble yet rarely manages to cop the mojo, and a great tube amp actually does reveal stuff you could be missing in your recordings...besides, when friends come around you can bore the crap out of them by showing off your tubes...trust me on that one. Has anyone ever said, "hey man...look at this lovely Class D module?" Maybe somebody has, but who cares?
