As we all know, there is no need for oxygen free copper. It offers no benefits in audio applications. Nor for car starting applications.Where do you get oxygen free jumper cables? I'm having trouble finding them at my local auto supply.![]()
Other (anecdotal) reviews regarding Class D have said that the distortion is low, power is abundant....but mid's and lows lack texture and slam.
Agree on the 2nd sentence. But education by demonstration is useful too. We don't need to turn people into scientists to make them aware of how senses don't work in isolation, that one input channel integrates with other inputs and memory to produce perception. There are lots of good demos how vision is lot more than imaging from the eye, e.g. we can show a lack of color discrimination outside the center field and that the color we see out there must then be coming from somewhere else. It would be good to collect a set of such audio demos.The only antidote is education in the nature of modern electronics (pretty much universally transparent) AND the mechanisms by which our human auditory system fools us. Calling people mentally ill will not help (and is insulting to those who suffer from actual mental illness)
We can point to D amps with plenty of power and to non-D amps without. So a classist account doesn't work there.Slam: sufficient amplifier power to play dynamic range peaks without clipping;
If it describes the recording then it doesn't describe the amp.Texture: fully subjective reviewer's creative way to rather describe the quality of the recording they're listening to...![]()
Looks ok except for color coding and insulation. Do it again properly!Works for me!
It's not welding cable, but it is 2AWG, so I've got that going for me, which is nice.

And bi-wired too, because I could, at speaker and amps, same terminals both ends, all from the junkbox.
:P
Gotta handle all those Cold Cranking Amps the battery -eh, I mean the amplifier can supply..I use 2 pairs of car jump leads.
I don't know for sure without comparable bench test results. But I am inclined to assume that all three of those expensive amps are competent. Even if the Hypex and Purify amps test better I would expect that the differences will not be significant in practice, assuming all are suitable for your application.Getting ready to purchase a Buckeye NCx500 2 Ch amp to drive B&W 802's. I have read glowing reviews and Amir has put this on his recommended list above other seriously expensive amps. I was originally considering ATI 6002-2, Anthem STR, Mark Levinson 5302. From reading reviews of the Hypex and Purify amps, it seems that the new class D amps are outperforming the "higher-end" A/B monsters. Is this actually the case?

I'm in the process of converting a stereo 3-way passive speaker to fully active.
I really like your post and argument.Don't get me wrong, I loved the AHB2s, but the Hypex measure almost every bit as well as the AHB2s and are audibly identical.
In this case the ears don't matter, as they won't perceive a difference. You heart probably won't notice a difference either, unless your brain causes your blood pressure to increaseI believe I can answer this. Your ears, brain, and heart matter.
Had there been a discernable audible difference in favour of the AHB2s, I would have kept them.However, I have a question. Hypothetically, had there been an audible difference where the hypex was found lacking in comparison you may have stayed with your AHB2s (inferred from your post). I am curious, is it correct of me to come to this conclusion?
I didn't expect there to be any audible difference between the AHB2s and the Hypex, but I wanted to be sure and compared them level-matched on some familiar tracks to see if I could detect any difference. I even listened with a mono Hypex and and a bridged AHB2 (level-matched) as a stereo pair.Pressing the issue, you already had the data and trust the test results. What could you possibly have learned in a non scientific approach to comparing the two?
You won't find better sound by looking at amplifiers.For me it's not a question of missing something specific, it's the question of what does better sound like and how do I get that better within my very limited means. So mostly it's fomo.
Thank you very much for your thoughtful reply, and for not taking offense.Had there been a discernable audible difference in favour of the AHB2s, I would have kept them.

If you haven't already, then take serious stock of your room. Get hold of a microphone (a UMIK-1 costs about US$100), download a free copy of REW, find one of OCA's guides, take some measurements and do some room digital correction. I promise, you will gain more improvement than with any component change.
This will be my next purchase and endeavor. I must admit this frightens me more than just a tad. I have no idea how to interpret any of the graphs or charts you both know and understand.If you haven't already, then take serious stock of your room.

I have come to trust the pink panther and what the consensus seems to be. It's sad, I know, but it is pretty much the best one can expect of me at this stage of my life.
I hope they are better at audio than at typography and visual design.
There's a really good pdf tutorial linked in the video description.
