Does anyone know if JMA's Mark Deenen is still active?

After missing out the other day on a Juicy Music Audio Peach II preamp being sold here by JMA's Mark Deenen, I got motivated and bought a standard Peach with intentions to have Deenen perform his current upgrades.

I assumed that since he was selling a preamp that meant he was available, but he hasn't answered any emails sent to the address listed at www.juicymusicaudio.com.

Does anyone know what the deal is? I figure he must be in his 70s and perhaps is completely out of the game. Maybe someone was selling the preamp for him.
