Oh how I wish Class D amps ...

Anybody ever heard the International Rectifier 'd' offering?

I've got a stereo module out in the garage needing a +-50 volt ps / case/ and all the wiring / connectors.

They sell OEM and I've never seem 'em referred to at all anywhere.

Another poster stated: "Sir Timtim,with a price difference of around 4500 buckaroos i would expect complete annihilation." refering to how a non-class D amp (McCormich to be specific) compared to a class D amp (W4S to be specific).

This is where the line needs to be drawn. The class D amp manufacturers and the owner proponents of them make statements that these amps blow away the best of the class A amps at many times the price. Yet when anybody compares them to another (non class D amp) at a higher price and the class A (or whatever) amp wins, this reference to price is always drawn.

Are the proponents and manufacturers therefore saying that "their" class D amp only beats faulty amps that cost much more or the "good" amps that cost much more?

I honestly cannot put my finger exactly on the part of the class D amps performance (that I have owned and/or auditioned), but I do know that over time installed in my system I listen to music less and enjoy it less when the class D amps are installed. When putting my class A amps back into the systems, I find that I return to listening to more music and enjoying it more.

Is there a future where class D amps will compare performance wise with the better class A amps (regardless of cost)? I sure hope so, but so far, I have not heard a class D amp that can compare to the class A amps that I "like" or own.

Most recently, I installed my BC Ref 1000s on a pair of maggies I picked up recently, and this seems to be the best I have heard from these amps. But I have yet to install these speakers on my main system with my class A amp as a comparison.

I think it is just that to SOME people class D sounds great and for OTHERS not so great. You happened to be in the second group. Some reviewers and makers (like Jeff Rowland) love class D while others hate it. It is all subjective.

On the other hand it would be hard to find 2x1000W class A amplifier to compete with BC Ref 1000 not only for monetary reasons but also for power requirements (10kW@110V=91A)

"On the other hand it would be hard to find 2x1000W class A amplifier to compete with BC Ref 1000 not only for monetary reasons but also for power requirements (10kW@110V=91A)"

Not to mention size and weight.

I pay no attention to this sounds better than that discussions. There are many viable high quality options. You just have to pick and chose. Everyone has different wants/needs/requirements.

The undeniable advantages of Class D is size, weight and power consumption. Also frequently, but not always, cost. That matters to some (like me) and not others.

I do not expect any new amp technology to sound radically better than older technologies categorically these days. There is a limit to how good any system can sound, usually determined most by source material and listening room characteristics.

I will say that the clear benefits of Class D are of the most significance when compared to similar high powered monster amps.

In cases where smaller, lowered powered Class A or Class A/B amps suffice, Class D amps may still suffice as well but they tend to lose their distinct advantages.

Any of the class D users driving a pair of soundlab speakers;if so whats your opinion?
