infinity 1b's- should i go tubes for top end???

audio friends,, i have infinity 1b's. a parasound 3500 for the bottom end and a rotel 1090 for the top end. the sound?? i think it sounds great. smooth and clean with great power. everybody says tubes for the top. to do this would mean selling the rotel for maybe $1000 and having to put out another $1000 to get say a 100wpc setup. amps in my range would be something like rogue 150's, audio research vs110's, cary slm100's. lets face it, i would want at least 100 wps for the mid/tweed panels. the BIG question is on just how much of an inprovement in sound is there going to be??. everybody says the rotel 1090 is a great amp, i tend to agree, and it does sound good. i would just hate to spend the time and money without decient results. and the reliable factor. the rotel probable will last for years. tubes?? how much up keep will they be just to get a decient year out of them. can someone convince me either way.

If you were close enough no problem, but i dought that's the case.Do you not have any options to try any tube amps in your area?I really think you will be quite impressed and I was a skeptic when first reading about this same combition with the vintage Infinity's.But a good deal came my way and WITHOUT hearing the amp bought it and I'm not going to consider a ss for the topend again while I own Infinity's anyway.
Like anyone else I like to try pieces before buying but everthing that I bought the Mac with the 2b's was one of the best investments that I've done.If you can I hope you can try!

Mixing tube and SS amps to the same speakers sounds like a risky, overly complex, and potentially expensive solution unless you really know exactly how well the amp configuration will play with the specific speaks in question based on experience of others.

Personally, I would not go there.

If the speaks are a good match for tube power, just find a good tube amp that fits the bill or, particularly if speakers are not tube friendly or you are tube shy, consider using a good tube pre-amp. Switching to an Audio Research tube pre has produced wonderful results from top to bottom in my system, and the sound is just very clean, smooth and effortless, not "tubey" sounding at all.

Hi Mapman......not a risky situation of mixing tubes with SS amp on these speakers. I have heard 3 RS 1-B systems and they all used SS on bottom and tubes on top. Just need to follow the instructions when connecting the amps to the crossover. Infinity always felt SS amps on there servo controlled woofers were a better match. However, as I said before.....go for it...it you can get a monster tube amp for the bass (say a Hurricane) and one for the top...boy, give it a try!!

thank you all for your responses. im going to try some tubes for the top. my first choice i think is going to be the rogue 150's. they are resonably priced and have good power,something the 1b's like. if anybody thinks they are not a good start, im listening. tell my why. i know there are alot of tube amps out there but im not into paying over $3000 for them. i think these will do the job.
