 Would you pay nearly $100,000 for an amplifier?

This is as close to perfect as any amplifier in the world has reached and it's Australian.

When I read the specs my initial reaction was disbelief. My view was shared by the other engineers in the office.

But apparently it's true and the design is a real breakthrough..

There is a VERY interesting story about the company, the people who developed it and how they did it.

At one time, and if money wasn't an object, and it had valves, I may have but not now, due to hearing loss (not total).

That said, I've always believed that if money is to be spent, spend it on the loud speakers rather than the amplifier and this was backed up by a bloke keen on the subject who said to me that if the amplifier will amplify signals between the critical 20Hz - 20kHz range then it is doing its job.

That said, this beast doesn't look bad. I like the inclusion of the woodgrain at the base.

A valve a day keeps the transistor away...

Their patented ultra-low-distortion circuit uses both positive and negative feedback!

That seems to be one of several patents held by this entity. I believe the latest amp uses Class D techniques and a digital implementation of the PWM.

In answer to the original question, no I wouldn't buy it, even if it was gold plated.

The money would be much better off growing in super.

And I wouldn't be able to tell the difference (if any) due to hearing loss.

You can pay more or equal money and get much less performance.

Remember Western Electric?

Oh but they must be better, they have that tube sound!

A pre-war Western Electric 1086 amp can fetch as much as a Halcro, especially if it's loaded with orig WE tubes (262As & 300As) WE 262As are especially hard to find. I sold an output tranny for a 1086 a few years ago, got $1200, found it in a draw in a projection booth Smile

"..latest amp uses Class D techniques and a digital implementation of the PWM"

Reminds me of the "amazing" Sinclair X10
