One of the reasons I’d like to give these a go... Specifications
It’s gonna need every bit of those ratings to drive the 9’s! Without dropping a name I was advised they’re rated into 2-Ohms. It’s worth a go... |
joysjane Don’t think your gunna like this It seems the WFS SX-1000 uses the same B&O 1000ASP ICEpower module as the Bel Canto Ref1000M monoblocks. Stereophile say they turned them selves off when presented with a 2ohm load, which easier than the Kappa 9’s load which is a below 1ohm horror load. "Ref1000M monoblock offers very high power from its diminutive chassis. It does work best with higher-impedance loudspeakers" Maybe it’s time to sell the Kappa 9 if you really need to go class-D My friend with Infinity Renaissance 90 little easier load than the 9’s was trying to do the same with Class-D’s, didn’t work out either, went back to his big Krell, which luckily he didn’t sell.

Yep, WFS SX-1000 uses those same modules. Spec sheet specifies 2.0 ohm minimum load, as well as 40 amp current (peak). Unlike the Icepower 1200AS1/2 being rated at 2.7 ohms. Also included in the specs:

Hi joysjane, FWIW as it might not be the same animal, I have a five year old W4S ST1000 and it could play Maggie 3.6's loud but with no control of the bass. It had trouble with Thiel CS3.6's and was a joke with the CS5's. In my set-up, a Coda CS (300 WPC 8 Ohms, 600 wpc 4 ohms) did much better but got constrained/harsh with the CS5's at higher volumes. My current amp, a McCormack DNA-500, is effortless with the CS5's. Any change now would be to eliminate my perception that I think I still hear a bit of grain or there is a lack of the sound coming out of a black silence. Based on listening to a X350, Pass might be better but they are hot and huge. Again, FWIW. Thanks for listening, Dsper |
