I own almost their entire line {no sierra towers} but sierra books, 170's, 200's, and 340's... And I have to say, if you dont like how they represent music, you dont like the music.. They sound how the music sounds, kind of like NO attitude of their own....
I try to buy other brands but their is nothing I like better... I do like my Wharfedale 2.2 setup, but it was affordable and looks great, I was going to go with sierra towers but my entire system cost less than a pair of them towers, soooo...
I will hear a set of speakers and either like them or not within minutes... I heard the E55ti and before the song {Bruces candy's room} was 40 seconds in I new I would never own them speakers, I dont know what was missing or what, but it didnt sound good to me, it may not have helped it being a song I know in and out, but that is what you want to do, play a song you really know and make a decision, if you hear new stuff that impresses you with clearity and resolution then you may have a keeper, if there is something missing and its not how you remember hearing it, then pass... If the highs are too forward and the lows are too laid back then pass...
I heard the tekton lores and Knew rite away they were special, I always audition Bruce {I have seen him live 17 times and heard him played on everything from ipod intergrated speakers to d7000 headphones {they were impressive, but out of my price range}, and when I played him through the tektons, it reminded me of every concert I ever went to, this may because of the Eminence's pro audio lineage or the full range foundation but it was great and I had to have them... Now they are rite by my bed, and get their share of use....
Just look listen and buy something you will enjoy...
Im listening to my 2.2 rite now, my wife is sitting next to me with her ipod in , and Pink is playing through shuffle, I wouldnt change the sound 1 bit.... The only change I made to this system was a set of custom made 100hz high pass xlr xovers from Stan. And that just cleaned up the low end when playing extra loud, it free'd up power for the mids and highs, while letting the subs do their thing with no interference from the 6.5" woofers...
Anyway, give the ascends a try, Deena over there is a peach, she will be a huge help and nice as pie... They make a great product for a great price...
