Well, it took almost two month and much more money then I thought but I was eventually able to get very decent sound out of monitors. The SL600 sitting on my “fundamental channel’s” tripods did not do well as I told before and I was forced to sit them in their original stands. Also, I have concluded that one of SL600 tweeters was defective. It worked fine but it did not sound as good as it did initially. Presumably it went down while was playing in my room. The bad part that I was buying the tweeter 3 times as the few that I have bought did not sound as good as I expected. Took some money to do so, well, “C'est la vie” … Anyhow, all my experiments with better MF driver and tweeter did not succeeded and I end up with driving SL600 as they are, with a moderate high-pass at 70hz. Of course a separate dedicated LF sealed Scan-Speak section compliments the SL600 under the bottom from 100Hz and down.
Wow, what an interesting sound! Different but very interesting! Also, what is wonderful job the Lamm M1.1 does on the SL600. I still would like to have the M1.1 to be slightly less granular and less abrasive but it would take a different amplifier. Still, the M1.1 inhale very interesting sound into the SL600. Surprise, surprise it have very unexpected dynamic sound, despite of its 88dB misery and do not fall apart easily with complex music. I was playing on my new monitor setup the Shostakovich’s 8th Symphony, properly performed and mastered. What an interesting things. The their movement should be Mahler-like effective and cinematographic however it should be also in the Shostakovich unique style be trite and vulgar. Most of audio do it effectively pornographic, stripping that sense of self-duplicated disdain. The M1.1 with SL600 did it right as it should be: a perfect salsaof the dual baby-tornados from movie “Twister” dipped into Russian hair-down self-Moronity and Soviet dancers of comedians…
The only thing is that I feel that I will burn them quite fast. After Macondo, that I generally listen quite loud (because I can) I have tendency to drive the SL600 relatively too hard. Well, if they will not live for long then they will have a good short live (I got a couple of SL6 for parts). I wonder if any cold running, AB, good sounding SS amps out there to make my “summer during global warming” setup?
