Driving SF Extrema with one BAT VK-60 ?

What's the driver configuration, sensitivity and impedence of your speakers? I am not famaliar with them. I run a VK-60 powering my Avalon Eclipse, which everyone says is a power hungery speaker with no problems. My speakers have a tweeter and a 9" mid woofer, impedence is 6 ohms and they are 86 or 87dB sensitivity no problems at all. Good luck

I use a McCormack DNA-2 with the SMC Revision A.Fantastic sound.

Ted, i do not think one VK 60 will be able to power the Sonus Faber Extremas. The Extremas need lots of power. Are you serious, your friend said the Extremas sounded good with a 300B amp. Unless it was that high powered VAC
300 B Amp, i dont think any 300B amp would sound good with the Extremas. My friend is using 2 Meridian 557 Amps bridged on the Extremas. This combo sounds amazing. I would think, your Rowland 5 Amp would be a much better on the Extremas, then the VK 60. The VK 60 is an awesome tube amp. But i dont think it will have the power for the Extremas.

I'll have to 2nd tireguy's opinion. I have one VK60 driving Wilson Watt 6's. Most everyone says this is a very difficult load. Impedance is 4 ohms and dips lower than that at certain freq's.

I'll take more one day, either a 2nd vk60 or the new vk75se, but it's been great for the last year. The VK60 can drive more than you think.

I would say the VK-60 would work, but would recommend taking a listen to the BAT SS amps, which are exceptional and would probably better fit the impedance and current needs of the Extrema.
