You mentioned the problems with the dynamics of the LRS’s.
Since last month I have a pair of .7’s and, indeed, the dynamic was very blurry while using the Marantz PM7200 Class A /AB Integrated Amplifier Gold champagne, which was excellent for a big, Tannoy Speakers. With the ’7’s it didn’t work so well.
Then, after a research I decided to look for a more powerful amp, which could give more current to the whole Maggies stripes, especially for the more dynamic parts of music. My latest purchase was Pioneer M-73 Urushi Reference Power amplifier, which appeared to be a perfect match for my .7’s. Dynamic of this system is unbelievable! The drums introits, acoustic guitar solos or even the symphonic music, including the operatic performances, are completely different with the wider, more rich and articulate sound. The same symphonic orchestra with the old Marantz amp sounded like half-sleeping bunch of guys led by the lethargic conductor. After changing the amp the same record was a completely different story. The whole orchestra was playing better, conduction was energetic and the sound performance was far, far wider, I would say, with no precedence.
I recommend to everyone while using the planars you must consider and think well about the proper amp, matching this type of loudspeakers. If you’ll ignore this passage, your Maggies will never sound on the top of their capabilities.
Cheers and enjoy Your top quality Maggies!
