Hi Edmond.
My buddies who have the Salks with the Ribbons always thought the Nrt domes were not as accurate in terms of timbre(instrument) sound etc. The combination of the Nrt and my previous prototype crossover (which now is new and they have yet to hear) were the source of the "forwardness" they heard. The Nrt was an improvement to me and to them but still not the sound they were after or preferred. We are hoping to all meet up so we can hear all our new gear after the holidays.
As for my thoughts after getting the RAAL's, they are better all around so far. I have not found anything in which the domes surpassed them. They do not sound any more forward or bright in comparison but offer extended highs in such a smooth manner. With the presentation being so smooth, they may be a hair less forward sounding than the domes, with no hint of sibilance whatsoever.
I feel my buddies will truly enjoy the Towers now with the RAAL's. They are ribbon fans and most only have the LCY version and the RAAL is even better
To me, the RAAL's are extemely accurate and offer the extended highs without any harsheness at all. Whether or not you consider them too forward, is tough to say. In home demo my friend
Good luck,
Brandon
