Hi everyone, Long time no talk. Been extra crazy at work but getting back to normal crazy so I finally had some time to build stands and hook my A15s up to the long term reference system and thought I?d share my initial impressions. The short version? pretty damn good but they need some massaging. This is my first intimate experience with a mantaray horn and I gotta say I like them better than the sectorals. To my ears they are much smoother though their pass band without losing the immediacy and snap you expect with a horn system. That being said, I think they are running a couple of dB too hot in the A15s. The first thing I?m going to try is tweaking the high pass down a notch. The woofer is pretty damn good too. I don?t think it has quite the speed of a 416 but the LF extension is nice, subjectively about the same as my KEF 104/2s but notably more efficient. I?m gonna give the 104s the edge in the upper bass detail department but that is a high mark to hit. The A15s win hands down in the dynamics department, with a 50 watt class A SS amp they were hitting 113dBc peaks without a hint of strain. They are also considerably more revealing in the midrange than the 104s, Everything I hate about CD was laid bare to the point I could barely listen to one. Switching to the vinyl front end helped, it?s tuned on the sweet side and made for a nice ying -yang combination. All in all a bunch of fun and I am pretty much committed to seeing what they can do since I carried the things down the stairs by myself and dread the thought of making the reverse trip. :-)
