Conrad Johnson CAV45-S2 8 ohm? 4 ohm? Other?

Anyone here know what the Conrad Johnson CAV45-S2 integrated amplifiers speaker terminals are tapped at? There is only one set and not the usual 4 and 8 ohm ones. I can't find the information anywhere, not even in the manual. Very odd. I used to have a VTL IT-85 and the terminals were tapped at 5 ohms. Thanks. 
Mezzanine, the factory can configure the amp for 16 ohms, which would be what you need.

Hi  mezzanine give me your opinion on the S2.are you using a turntable for a source? I'm thinking about getting one. any  info appreciated.
Tone Publications has a new review out on the CAV45S2.

Mine has become my daily listener. Giving my CJ ET7 and CJ Classic 120SE some time off for good behavior. I will more than likely do the Teflon cap upgrade on the CAV45. It is so easy to listen to, and I am driving 4ohm 87db speakers.
The CAV 45 is a great integrated amp......  its more like an amp with a volume control .   Stripped down, low parts count, sweet sounding.   If I were to buy an EL34 integrated amp, that would be the one.
