Are they going to sound much better for music playback compared to his old designs?
My 750s aren't that great at stereo tbh.
With the older Miller & Kreisels, the better sounding models for music were the ones using the 5.25" mid/bass drivers like the 650, 750, 850, and 150. Even so, music quality wasn't great, in my opinion. I think with the 750's they just lacked a bit of refinement. The 150's were more refined as they used three HF units instead of one, which meant that each unit didn't have to work so hard. The new Quattros use four, so things are looking good so far! The 750's weren't the best built speaker either (I used to own some), and while I loved the sound of them, it has to be said that their build quality drew a bit of attention to themselves sonically. The new KK's over the old M&K's is like comparing KEF Q series to the R series - the difference in build quality is leagues apart.
When I sold my last set of S150's, I replaced them with KEF Q300's. I didn't really expect the Q300's to better them, but it was the start of an exercise to find a worthy replacement for the 150's (Miller & Kreisel had closed its doors at this point and ceased trading). Whilst they were very good for the money, they fell short in many areas, but they were streets ahead when it came to music. The Q300's just made them sound musically flat, sounding fully three dimensional in comaprison, which meant these £2k per pair speakers were being outdone by a pair of £500 hi-fi speakers for music.
Will the new ones improve on the old ones for music? I'm sure they will, firstly seeing as it has been many years since Ken's original designs were developed, and secondly because it was the main area that was open to the greatest improvement, and with Ken being first and foremost a two channel enthusiast who records his own music, I'm sure he will have improved this aspect this time round. How good they will be we will find out next week.
What I find exciting is the fact that Ken has a potential S150 beater here in a 750 sized/shaped package. Many used to want S150 performance but refused to buy the squat box the S150 drivers inhabited purely on looks, but now that they can get that (and possibly more) in something more slimline and conventional looking, and certainly more accommodating - I think Ken might have a rather hot product on his hands here. And all for less than the S150 too...
