Today I had a fun, rare audio treat at my buddy's house. I brought my 4367's over to compare to his K2's.
We had several other Musicians/Audio-Nuts over for the same event. We listened to some records, but mostly streamed Tidal through the Mark Levinson 519 Player. The rest of the gear is also Mark Levinson, 52 Preamp, and 2 each 533 amps.
Each speaker was bi-amped of course. The extra 2 channels of the amps are usually used to power the centre channel when the room is being used with his Synthesis gear in Cinema mode.
Going into the "audition" I was hoping that the 4367's would be superior to the older K2's because of their "superior" horn profile. That was my bias anyway. I changed positioning of the speakers 6 or 7 times in order to attempt to get the best from both speakers.
In the end, the K2's were just more homogeneous top to bottom, and spread a great, wide sound-stage without calling attention to any particular part of audio spectrum. The 4367's hit harder in the bass, but the treble was more shrill or pronounced. In my own system, I've unconsciously adjusted my gear to tame that forwardness .
This impression was shared by all present.
Those who hadn't heard either of these speakers were absolutely stunned how loud the music could be played cleanly and enjoyably. Great, foot-tapping, chest-thumping engaging speakers.
What fun!
