Jsonic - You won't need a sub. How many speakers hit the lowest octave without a sub? Also, wattage is plenty for ~97db speakers. You are looking to set up a "tube" system, no? Go with solid state equipment if you want maximum extension at the frequency extremes. But if you want a tubelicious, musical, and real life like presentation with deep satisfying bass and warm luscious non fatiguing highs, the FI-X/Hornshoppe combo will rock. Did you say classic rock/bluegrass/country?? P-E-R-F-E-C-T
Why the FI-X + Hornshoppe combo will drive to insane levels:
1. SET circuits are simple, creating the purest signal possible. Plus the FI is direct coupled meaning no capacitor in its signal path. Pure sonic 3.5 watt bliss. And to maximize these clean watts we have....
2. Hornshoppe's are single drivers without a crossover. All crossovers burn up the first few watts as heat regardless of rated efficiency. Here efficiency is maximized. And did I mention horn enclosures play louder (about 3db) than regular speakers? Along with their benign impedence (easy to drive) and ~97db at 1 watt/1 meter, you won't use more than 1 watt, yes 1 watt, to get to an average audiophile's listening level. Oh yeah one more thing about how efficient this set up is...listening at low volume levels when all is asleep does not hinder dynamics.
Like Restock says, system matching is key. If you go SET, get 95db+ speakers with high impedence drivers without a crossover (or simple crossover). And in a nut shell solid state set ups work best with 100 watts and 87db two/three way rubbery driver type speakers. Mixing between the two usually don't work as well as sticking to the formula (there are of course exceptions, just pointing out Ferreri's like premium gas, while Honda's don't mind regular unleaded).
These products btw have 30 day money back guarantee's so you have nothing to lose. Ed and Don are also stand up guys that have been around and always willing to help you out. Give them a call/e-mail for advice, ask them what type of music they listen to, tell them what you listen to and type of set up you're looking for.
