Whether you end up being happy with tubes may depend on how carefully you select a tube amp/integrated to match your speakers and which produce a tone you find attractive.
I'm not familar with your speakers so I won't make any recommendations on amp types, but for example (remember MWilsons comments on the generic sound of tube types), if your speakers/system are more on the cool side of neutral and do not have really deep bass and you want to warm it up an amp based on EL34's could work quite well, an amp with KT 88's might as well, but you probably would not like either KT90's which can be bright in the highs, cool in the mids but very tight in the bass, or 6550's which are not as bright, nor as tight in the bass, but more or a balanced tube that will let your components sound pass less altered.
In addition, in selecting your amp, you will want to insure that it has the ability to drive your speakers in the first place, which has all to do with minimum impedence values of the speaker, its impedence curve (which should be as smooth as possible - no big impedence spikes or dips), nominal impedence of the speaker, and output impedence of the amp itself.
Don't get wound up about tube 'rolling'. Its a hobby within a hobby. Ultimately though it can be one of the most fun things about tubes - if you want to change the tone of your system.
Lets say for example you buy a new CDP which initially sounds too cool in tone, your amps ability to accept a wide variety of tubes gives you a lot of flexibility in changing the tone of the CDP. You don't have to get a new CDP, just a couple of tubes.
However, I have found that most amps which accept a wide variety of tubes usually sound best with the type of tube which their design was based upon. I would not buy an amp designed around a KT88 and expect it to sound as good with an EL34 as an amp designed around an EL34.
FWIW, YMMV, however despite comments of others, don't let anyone kid you, changing tubes makes a difference. Sometimes its small, sometimes its big. But there is a difference - it just depends on whether or not the difference is in an aspect of audio that is important to you (for whatever reason).
Hope that helps a bit.........
