My setup is: MacBook Pro + wireworld platinium + intona + regen link smal cable + regen + curious USB 0.2 + aqvox ps + audiophileo + i.AM.D v200 chinese digital amp.
the sound is really good but intona on its own is,from my point on view, the main contributor to the overal sound Quality. With the regen, the sound is even sweeter but a little dark and less airy.
when used with the regen, the green led light stay ON permanentely wich means there is a fimware or power supply default. When i disonect the regen from the audiophileo the led flashes as intended. But ,even more strange, when i remove the regen from the chain, the intona is so connected directly to the audiophileo and the Green led flash ???
