There is nothing at all about the special 40s that sound metallic, edgy, harsh, etc. they are the definition of smooth, big, bold, with slight warmth, tremendous bass, sweet high end and have amazing imaging and soundstage width and depth. These are the best speakers I’ve had in my room under $10k. I’ve had a lot. The 40s need the right amp. Not watts but current. I’m running them in my 12x13 room with a 20 watt tube amp, a 40 watt tube amp and a 200wpc solid state. By far, these open up and give the most magic with a 20wpc raven nighthawk v3 amp. I couldn’t want for better or more. These speakers are jaw dropping good. With the wrong amp they can sound thin, and a tad hard. That’s the amp, not the speakers. They beg for tubes...
