Is a Tube Amp Capable of High Current?


I need your help.

I have a pair of VERY inefficient speakers (Platinum Solos), but am also a big fan of tubes. I know that tubes can work with power-hungry speakers as I have done it with a pair of Magnepans...BUT...I'm not certain that it will work in this case.

The speakers are rated at 84db with a nominal impedence of 6 ohms.

I am purchasing an Audio Research D-125 which is rated at 115wpc.

I know that people always say that "tube watts" are more powerful than solid state watts, but I'm not really sure what that means. I also always hear people say that you need a "high current" amp. I've always taken this to refer to solid state, but can this be true of tube amps as well? Is the ARC D-125 high current?

I'm not a head-banger and certainly prefer quality over quantity when it comes to sound. Also, my room is not particularly huge, so that shouldn't be too big of a factor.

I need your advice. Am I setting myself up for disappointment? Does a load like this inherently require solid state amplification?

Thanks!

I second Angela100's suggestion of Wolcott amps (disclaimer - I'm a Wolcott owner & dealer). No, they won't double their power output going from 8 ohms to 4 ohms, and again into 2 ohms, like a beefy high-current solid state amp will. But, they will deliver their rated power into a 1.7 ohm load, which is pretty darn good for a tube amp. Especially for a tube amp that uses EL34 tubes, which are traditionally noted for their midrange performance, rather than their stability into difficult loads. But Wolcotts are the amplifier of choice of many Sound Lab owners, and Sound Labs are a difficult speaker to drive.

A feature of the Wolcotts that is quite welcome with demanding loudspeakers is the adjustable output impedance control, which allows the user to fine-tune the amplifier/speaker interface.

I'd be happy to answer any specific questions you might have.
