Personally, I think traditional floor standers like these are a mistake for you, both becuase of the small room, and because of the passive nature of your speakers, as well as limited power you can provide them.
That said, I love the little Jolida 302with the right tubes! Actually, I like the 6550 ran SJ502b better. Still, those little tube bugers are great sounding bargain gear.
Yet, 50 w/channel is not goign to give you the control and authority, even at low levels, especially with passive speakers you're mentioning!
Now the tubes, as mentioned above, will still have some snap, and will soft clip better than SS, that's for sure. Basically, tube gear is more forgiving of distortion on speakers, yes I concure. And, the tubes do do best on the Energy C1,c3,c7,c9 designs from my experiences. They are a bit foreward and etchy, and like tubes...you bet. The Kef's I've heard briefly, and struck me however as better speakers through and through. but then I like the Kef sound a bit personally.
HOWEVER, again, I still think for rock and heavy dynamic stuff, having either active speakers or enlisting some bass managment to your system is the way to go. I'd even go so far as to recommend picking up the Outlaw Audio ICBM, and putting it in your system, yes!!!!...and thus integrating a well possitioned and preferably "EQ'd" sub into your sytem for best control and dynamic range!
The ICBM will add a "smidge" of softening to the dynamics, but very very little...and nothing compared to the loss of control and dyanamics you'll otherwise have if you simply opt for the "full range" approach from your passive speaker choices listed above...not helped any by the 50w/ch indeed.
In the small room for certain, but in bigger as well, I'd like to see you go down the road I just mentioned, but with perhaps smaller more accurate transducers, I.E., mini-monitors for your room! Spending more on "quality" rather than quality is a better deal. You can then take the time to get a more flexibly placed subwoofer of high musical quality in the system, with things crossed over under 80hz to the sub! You're dynamic range will be leaps and bounds(at least 100-200% better dynamically) with things crossed over to an active participant in the bass region, namely a powered subwoofer(s).
Another option for you in that small room/low powered(yet potentially musical) system is to do speakers with powered woofers built in! Def TEch BP2006's are such, and they are foreward, dynamic(8" powered 100w+), clear, and sound great with tubes. I actually put these on par with the Energy C series, but they're bipolar...if that matters to ya. It's a consideration. In this senario, your amp wouldn't have to drive the difficult bass, just the mid/tweet combo. You could also "EQ" the woofers for absolutely much more dynamic, detailed, fast, and accurate hard hitting bass! Another advantage of active speakers(or active woofered speakers).
This set up would act like a well integrated "sub/sat system", just not as ultimlately flexible, yet entirely effective!
Of course, you gotta like the speakers to begin with. And those DO DO WELL WITH TUBES!..believe me. Although, they aren't as ultimately resolved as the best high end stuff...yet musical and fun for sure.
Anyway, you can check out other floor standing active speakers as options. Otherwise, I recommend smaller better monitors in a small room, crossed over to a sub with bass mangagment. You'll be way better off for rockin, definitely!
