And do some comparisons to some other high end Amps Solid State, Tubes and Class D’s, also in other systems I’ll do a more comprehensive review.
I can’t wait for your precise and articulate tribute.
In full knowledge that you may only change one variable between comparisons, all other things being held constant. This will invariably involve comparing components that are not technically equivalent.
But you know that, having read all of knowledge provided on Ralph's website.
No, not really. I seek informed analysis from one who is cool, calm and collected and in control of their cognitive facilitates.

Atma’s are good but overpriced....400 watt Peachtree is 90% there and costs under $3,000
So, you have completed a full costing analysis on all of the necessary inputs (defined very wide) in order to make this comparison?
Others may suggest the exact opposite of what you suggest - that Peachtree is utter junk and something that a person with more dollars than sense would consider buying.
Because 90% there is sufficient?
I say no.
Declare your interests. I have none.
What I do know is that I’d rather pay way more than 5,400 for a 100% "there" than 3,000 for something not quite "there" and possibly has unresolved component or design issues.
Why on earth would anyone settle for less at these price points? I buy for keeps, not to experiment.
|
The irony ! One of the best mfg of OTL tube gear makes one of the most highly acclaimed Class D amps yet. Go figure
What's the irony? Do you even know the meaning of the word irony?
That you say Go figure - you are blessed.

@ricevs Here is another class D amp that will be really good when it hits the street
Yeah, really interesting dude, on a thread about Ralph’s class D amps or any similar (??) Ganfet in production like AGD.
Some here and elsewhere may wish for you to hit the street. No, I don’t know what that means, either, but I’m guessing its like falling over and hitting your head on the gravel.
|
@twoleftears ~try ASR for size.... a happy AGD owner (OMG! also no measurements).
You own AGD and have not even looked at the website where a few graphs are provided like FFT, square wave and a couple other things (measurements) are provided.
Also the product manual.
In other circumstances I’d have enjoyed your considered opinion as you are an owner, but that lost me a bit.
I am a little disappointed that Ralph does not supply similar information. No way am I gunna buy anything without these pretty basic fast facts.
|
@tinear123 Just popped the lid as I do on everything according to my wife and since I'm an engineer and do tend to disassemble everything she is right.
I always enjoy a double entendre. Very dry humour.
Oh, wait, this is an American forum. My mistake.
|
@ricevs When you take your ego sword out and start swinging, you are not in a high vibration.....Do you love yourself, do you love me?
I dunno about others on this esteemed audio forum , but I'm sure something could be arranged elsewhere.
|
@holmz
some might still prefer the signal modified, or distorted, so that the 2nd/3rd harmonics were present.
Some of this may also bleed into people running tube preamps into SS/Class-D amps.
And this is a truth. I am such a one, for a variety of reasons. I am also careful to consider measurements (defined widely) for a component's attributes, again, for a number of reasons.
|
I think that this has been a tremendous thread. Thankyou, Audiogon, and @pstores
|
@jjss49 Perhaps not so weak and lame but rather the ill-considered rantings of someone who I suspect, judging by his incoherence and lack of respect for the English language, was drunk, stoned or high. Whatever.
Exactly what is the reason that you chose to paste that rant on a thread dedicated to discussing the finer points of the Class D amp made by Ralph?
|
@kuribo It should be blatantly obvious.
No, actually. Please provide exactly what tests you wish to be performed. One at a time.
I will agree with you should you be able to be specific, rather than saying just look at the websites of Purifi and download the information provided...that is quite a rude approach to maintain.
If you desire information, it is your responsibility to request it. Politely. I do understand that this is forum is predominately American, and I am not.
|
@kuribo That is quite a slab of tests. I think that someone who owns one will drop-ship one over to Amir at ASR. Probably a couple weeks turnaround.
I’d do it myself, but I can’t because I am on 50hz power.
Also, what I am thinking and I may be wrong, is that this is version 1 (that I know about). AGD are already into version 2, with version 3 probably next year.
This is unlike Purifi, which is settled and been in circulation for quite some years with its predecessor Hypex and variants.
They (Bruno and his silicon mates) are miles ahead in the abundance of research, and have the starters advantage compared to a new entrant in Class D - I think Ralph's amp have only been available this year?
|
@holmz I am assuming your’s are 230v then, in addition to 50Hz?
So it would seem like you may be a long ways from Washington state in terms of shipping.
I’d kick in some $ to help with shipping if Amir has a 110-220v transformer, and if Ralph says that 60Hz is OK.
From a couple posts on AG and perhaps elsewhere, Ralph has said that he is working towards making his amps available to the wider community who have 50hz/240V power supply. I am not the odd exception, as Wiki shows here.
|
@holmz My amps reside, with sufficient peace and dignity under the benevolent reign of King Charles III, in the country known as Australia.
|
@kuribo At $20,000US, for a shiny aluminum box and a fake tube, with performance bettered by amps at 1/20th the price, I can find little to attract me for a listen.
Yes. It is imperative that blokes who are creating Gan amps provide a comprehensive and transparent independent audit of their measurements.
Failing that, it only promotes doubt as to anything that is claimed. Spot specifications are useful for off the rack retail gear. Thanks maybe to Amir, intelligent audiophiles require a whole lot more before opening their wallet.
I am very disappointed that the Gan guys have not taken an initiative on this. Gan is superior to silicon - so, prove it, as many others do in a variety of components and are sometimes subjected to criticism. Everyone benefits.
I am not swayed by any philosophical art or flowery words. Just the facts, thankyou.
|
@sutts if Ralph’s amps can hang with the performance of the Merrill 116’s, well now that would be something special..
Upon what criteria would an assessment be made as to their relative merits?
|
@mapman Measurements may or may not even matter in some cases.
What are the cases in which measurements don’t matter?
|
@mapman The ones that come to mind are:
1) the published measurements are not sufficient or accurate enough to be useful
2) The user does not know how to properly apply the measurements
3) The user simply does not care and prefers to rely on other means to make their decisions.
I agree on point 1. Measurements ought to be much more accurate, They are currently so useless and sloppy. Ought to go to to a at least few more decimal places. We can agree on this. Or not.
Point 2 - that the user does not know. Yep. Many words could be used to describe that person. I won’t dare.
Point 3. Cool.. You have perhaps defined an audiophile - more dollars than sense. Some manufacturers rely on this aspect. And they are reading this with a mix of joy and dread in their minds.
|
Blushing, I was kinda jesting about point 1. Testing equipment is of course more than sufficient, and Ralph's considered comment is important.
|
A rather disappointing reflection on some of the regulars here who if they continue in their childishness the mods will likely delete this entire thread.
|
Talk about audio (however defined) on this esteemed forum. There are many issues to explore and many wonderful contributions. Address the many questions raised.
What is with this with character assassination? That is what inexperienced and puerile teenage girls do at school when they have a crush on some boy.
|
No way would I ever leave my kit on if I am not listening.
A Black Swan risk, one which is very irresponsible to do.
