Ill soon post a writeup on my speaker comparisons but this is an excerpt that speaks to the OPs dilemma. I bought a pair of 60xts along with a 50xt center over the holidays but they went back in the end. I really wanted to like them. Partially because they would be a major pain to return because of their size. I initially liked them but I found glaring flaws. First the good. They had pretty good sound staging, the fxt tweeter is quite a work of art. It conveyed emotion, liveliness, reality in the voices and instruments that are hard to get at any price level. ( I have paradigm signatures with the beryllium tweeters in my second system). I find the fxt tweeter less edgy and fatiguing than the Be tweeter.
Now the bad, first off, and this is the main negative, the build quality is bad for a 3k pair of speakers. The front baffle is made of cheap mdf and painted black. In my pair the speaker cones were not centered on the cut outs and looked cheap. While the piano black finish is nice, the gold plating on the binding posts started chipping the day I got them. Secondly, I found that since the bass drivers were so far from the tweeter midrange array, there was significant lobing. The sound was incoherent, with bass tones of voices and instruments separating oddly within space. Imagine hearing a voice without the bass weight, then imagine hearing the same voice through a door. Now together. Odd. This may have been due to the fact that I am only about 8 feet from the speakers. But I did not find the sound cohesive at all. I also found that though pretty great, the fxt tweeter was too directional for my 8 foot distance. This affected soundstaging, which only made it pretty good.
I now have a pair of Ascend Sierra Towers w/RAAL. Notable differences are that the the RAAL tweeter is not as crisp but just as detailed if not more so. The RAAL tweeter sounds very sweet, not as forward as the 60xt tweeter. One great benefit to this is that I can turn up the volume on the towers for room filling sound without hurting my ears. The RAAL tweeter had much better dispersion than the 60xt tweeter, soundstaging with the RAAL tweeter is excellent. Its a draw between the two. I really did like the 60xt tweeter, the music seemed "alive". The bass of the Sierra towers was much more cohesive. Lets just say the sierra towers were more cohesive, period. However there is less bass authority coming from the 5.25 woofers compared to the 60xts 8 inch cones. A sub is required for great two channel listening
. I'm getting my SB-13 next week
In the end I am very happy with the Sierra Towers. My decision rested on a last point that mattered most to me. Build quality, craftsmanship, and customer service. The build quality of the Sierra towers warmed my heart. Each speaker was wrapped in a thick felt blanket out of the box. The binding posts were solid brass, the drivers were recessed in the cabinet. Ascend hand matches the speakers, my pair has perfect side to side imaging. (the 60xts were poorly matched, I heard a few decibels difference between the front speakers) Dina, the sales and support person at Ascend picks up the after two rings and can walk over to Dave F. for any questions. (Ascend founder and CEO)
Hope this comparison helps. One note, not to the OPs question, but the Sierra Horizon center is much better than the 50xt ML center. That did sway my decision. I really did like the trio 60xts and 50xt center. I just wished that they were 1/3 cheaper. That would have justified the purchase for me, because I am a stickler for craftsmanship.
