To pictorialize the last paragraph…

… here we see the hardware pre minimal assembly. All connection points are superbly tidy and of top quality.

The 3D-printed Vibron footers conceal a hexagonal threaded shaft. That connects via bolt to the cabinet then the footer slip onto the stand-off.
Once perched on the stands, the combo seemed tailormade for each other. My tape-measuring then Google-walking skills had been up to snuff.

The quality of Viper's textured scales was surprising. I'd frankly expected a certain amount of imperfections due to print-head irregularities and droplet splatter. Reality was a stern correction notice straight in the shiny eye. Doubt had just been evicted, effective immediately. The competition—what competition, exactly?—really ought to lose a few sleepless nights just to demonstrate proper sportsmanship in the face of dominant defeat.

Viper's reptilian tongue reflects in a bifurcated sales strategy: Poznan direct or local dealer. The former is €4'400/pr prior to local taxation and customs clearance but with free worldwide shipping. The latter is €6'900/pr flat, all associated fees included. "I tuned Viper to sound good with drier class D and standard class AB amps. They definitely don't like very warm sluggish amps." Neither do I. No mushy peas for Viper. England is one island over. Their ATC SCM11 rubs shoulders with direct-sold Viper. On the mainland there's Dynaudio's Evoke 20 or something from any number of brands like Focal or Triangle. To get closer to Viper on ambition and execution, we'd need to look at the €10K/pr Serendipity by Wolf von Langa; or Joachim Gerhard's Surveyor which pulls even with Viper after Irish VAT. But such considerations are between you and your accountant.
