Another marketing gimmick?

As far as I can tell that is the case,  pretty bizarre but as you say there will probably be a market.

Perfect for the buyer "innovative stuff?"

A look at the manual, and it appears the designer even put orange LED's in the faux tube. This thing is just....odd.

It better sound good for $14K! Plenty of SS amps for less, that sound great.

There's always a market for snake oil. The real question is how big that market will be.

I'll wager you could put the metronome inside a tube and it would stop that annoying "ticking" sound!

you're on to something....let's collaborate$$$$!
