I really tried to like the Monitor Audio Silver 100, and other Monitor Audio speakers, too, but just couldn't. I've tried multiple amplifiers, including warm sounding Marantz and NAD (the amp character is highly overrated anyway). I've bought the Silver 100 twice and even listened to the 7G version, hoping for some improvement. Nope, just can't stand it. Even though the bass is wonderful, the highs are too shrill and loud.
I've been enjoying a pair of Wharfedale 230 for a few years and I've just bought a pair of Elac DBR62. I was afraid the Elacs would be too bright, since I'm used to the velvety sound of the Wharfedales. And yes, they are noticeably brighter than the Wharfedales. They are at the limit for me. One dB brighter and I would have returned them. The dispersion of the Elacs is a little erratic, but nowhere near as that of the MA.
I've attached a comparison chart. It's just two superimposed charts, I haven't used a comparison tool. (DBR62 in black, MA Silver 100 in red)
Even though I consider the Elacs neutral-slightly bright speaker, the Silvers are still even brighter, over the limit which I consider reasonable to use them. You just can't hear much besides bass and treble.
Also, it's not only the dB's. The MA treble has a metallic character, too, no matter what amp or DAC you use.
In fact, you can't even find that many brighter or shriller speakers than this on the mainstream market. Even KEFs are less bright and metallic. The only worse ones that I can think of are some B&W models which have ridiculously elevated treble, to the point I consider them a curiosity, not real speakers.
I lied to myself for years that the Silvers were ok, tried different amps, treated the room, sold them and bought them again. Nope! Just stay away from them if you want normal speakers. They aren't even neutral-bright, like Elacs or KEFs, they're just overly bright, metallic and shrill, there's no way around it.
PS: Also, equalisation doesn't work either. If you reduce the highs to the point you consider to be at the right level, the songs will sound strange and the metallic character will still make its way through the sound.
