Hopefully this brings the price of vacuum tubes back to earth...

Looks promising. Pero I doubt this will be patronized by the majority of tube lovers because most tube lovers are "purists".
I am already imagining the issues that will be brought about by this technology:
1. It really does't sound like a tube
2. It's not analog
3. It's unrealistic sounding
4. Who would want a tube sound without the lovely warm yellow glow of the tubes
(same argument with solid state and digital amps)
Though i'm sure there will be a mixed market for these. Unfortunately I think hindi siya bolt-on sa mga existing tube amps because of the power supply differences. Preamp or buffer ang implementation?
