some words from Germany about my M3 turbo S. I have them up and running for nearly 3 months now. Unfortunately I don't have a LIO. I used to have a Signature 16 from Vinnie which was very nice with my former Zu Soul Supremes. LIO unfortunately is too expensive for my budget.
After about 70 hours of break in I used them with four different amplifiers. First I tried a 300B Trafomatic Experience II SET and was a bit disappointed. Especially voices lacked the richness that they had when using this amp with WLM Divas and Zu Soul Supremes. The low end was a bit poor too. Okay, 8 watts per channel. I then switched over to a Melody EL 34 tube amp. With 2x50 Watts it has plenty of power but when played at higher levels it started to make unwanted noises. My guess is that M3s extremely high impedance at 1-2 kHz ( up to 200 Ohms ) is the reason that the EL34 valves acted that strange. After that I was done with tube amps in combination with the M3s.
I then hooked up a Class T amp which here in Germany is quite famous when being paired to Klipsch speakers. It is a chinese brand and here we call it "Poppy T-180". With this amp voices became sweet and the low end extremely deep. Hard to believe how deep these speakers go. But the soundstage was sort of limited. There was not much space between instruments.
I was sure that there has to be an amp who could do better and after some consideration I bought a Hegel H-160 for a special price during a sale of a big dealer in the Netherlands. I liked that it has a very good DAC built in and with 2 x 150 Watts at 8 ohm and 2 x 250 Watts at 4 ohm it has lots of power. And it has a damping factor of more than 1000. The bass this combo emits is insane. The soundstage is huge and all instruments are perfectly separated. The near live experience of this combo is shocking. It even got better when I removed the bass traps I used to use with all my prior speakers. My guess is that they are counter productive when using open baffle bass systems. At least they were in my room. As I saw some of you also use bass traps it could be worth a try to remove them and step away from the perfect room that is necessary for standard speaker concepts.
The only thing that remains is that mids are not as detailed as I was used to when listening to WLM or Zu. Sometimes when listening to songs which I know very well there is a lack of midrange information. Effects that I clearly remember from the past are less audible with the M3 turbo S. Maybe it's just because there is so much overall information and dynamics. Hard to tell.
What do you think about the midrange of the M3s? Are you satisfied?
The speakers are much more expensive in my country. With taxes, transportation and dealer profit they cost about 4,800 dollars here. But a Zu Soul Supreme is close to 9,000 dollars in Germany
If there was a bit more mid range details the cheaper M3 definitely would be the best speakers I had so far. And I had lots
