I have the Orchid with a WE396A tube and recently acquired a
Pontus II. I really like the Orchid a lot, but the Pontus like Ozzy said,
adds more resolution at the top end. Vocals are a bit more forward
and crystal clear. I seriously considered doing the Grannyring
upgrades, but in the end decided to get the Pontus II. That being
said, I can't part with the Orchid just yet.
