Raidho and Margules at AXPONA: Amazing how real it looks

I’m in the middle of an audition in the room where Raidho TD3.8 speakers ($119,999/pair) produce sweet music in synergy with two $6,000 Margules Audio U-280SC tube amplifiers running in triode mode. (JVS reviewed the amp in November 2017.) Suddenly, a deep-voiced guy speaks, just to my right: “Ever heard of the Purple Man?” Confused, I look in his direction. Nobody is there.

Being from Maine, I wonder if I accidentally stumbled upon a Stephen King tale.

But a thousandth of a second later, my brain races, confirming that – duh! -the voice is on the recording (nine seconds in “The Peppery Man” by Natalie Merchant). Now I am thrilled and embarrassed at the same time. Embarrassed because apparently I’m no smarter than my dog, who sometimes barks at other dogs he sees on TV. And thrilled because it’s not a surround sound setup. the incredibly The deep and wide soundstage is entirely the product of a stereo system designed and fine-tuned to near perfection.

Built with two 8″ woofers per driver that Raidho says works with “a patent-pending turbine-shaped motor system”, the impressive low end goes down to 24Hz. Above 400 Hz and 2.4 kHz, respectively, two 5″ mid-range speakers and a TD ribbon tweeter take over.

It struck me that the concave baffle of the Danish three-way should contribute to excellent phase coherence, resulting in a soundstage that was unsurpassed by anything I’ve heard from AXPONA. In my experience, most speakers emit primarily rear the imaginary line between the fronts of the loudspeakers. The TD3.8s, if properly configured, break free of this constraint, placing instruments and vocals in all directions. I heard a tuba that extended several feet beyond the right wall and a lead vocal that sounded so close I could almost touch the performer, even though I was about seven feet from the speakers.

There is a virtual reality quality to this amazing Danish product. They should be on the must-have list of anyone blessed with deep pockets and a thirst for state-of-the-art audio.
