Regardless of what you think, his LM4780 pcb _is_ good when it comes to the physical layout and I think it's fully professional in every sense.roibm said:

Poor guy.
Judging a design by a picture of a flashy PCB is really beginner's stuff.
I have it in my hand.... you know. 70 um coppper and lot's of copper areas and lot's of vias. Grounding, perfect! Beautiful looks.carlosfm said:Judging a design by a picture of a flashy PCB is really beginner's stuff.
How it sounds? I have no idea... yet.
OK, I had a hard time to say "inte helt och hållet" in english. I ment not 100%....carlosfm said:Totally?
They can't make good souding amp ...
Carlos, get down from the tree. 😉 I had try to build with this chip best amp with all of my knowledges about amps. Well, it play surpraisly good and I mean, that without problems I may compare it with your amp. All is only on one PCB, becouse I don't like tufts of wires, which you can to see in mostly of DIY machines ( and as I remember, in your too ) and don't like many questions about grounding, hum etc., which escort nonperfect constructions. From this look is my construction good enough and I mean, that better than yours. I was asking people here for interest for my PCB, but it is not my main business and after your attacks I have feeling, that better will be **** it. I have also different amps ( and better ) and I know very well " state of art " sound - be sure, that it is not coming from some silly GC.

Time out now, Carlos and Pavel!
Pavel if you want to put any of your designs on the "market", like pizza money or more... or less, do it Still I get lot's of hit to your pages and now and them I get questions wher to buy the pcb's (Pavel you are a bit slow to reply) so it's definitely worth a try.
It's still OK to organize a group buy or if you let someone else to do the job for you.
You could charge very little (just above zero profit) or you can charge a little bit more and donate some of the profit to the forum. Your choice.
Since you already have tested your pcb's you only have to put up a list of interest first. You will get 100 boards easily!

Re: They can't make good souding amp ...
But I wonder how you can tell your chip amp sounds better than the one carlos has?
Have you listen to his amp? Have you built your amp just like his? I don't think so. Then, how can you tell? Are you some sort of Upupa the Great-know-it-all?
To drop the pcb was wise considering your attitude.Upupa Epops said:

The minute is gone, may I continue now?peranders said:roibm, time out you too. Drop this subject for a minute.
😉
Peranders, to tell you the truth I don't like people talking without testing at first. If you like them, that's you.
As about your pcbs, I have all parts, all smd are in place, tomorrow I'll be listening to it eventually. I hope there is something more than just no DC at all, since this design took me a lot more to complete than brian's design. I also have a brian board with snake oil(bg), so it would be interesting to see how it compares to that.
Re: They can't make good souding amp ...
Sell it first, find out later.
I know how to make a silent amp, with or without wires.
It's not because you have a separate PSU PCB that it has to be bad.
I do that because it's more practical for me.
I agree that if you are selling your PCBs for everyone (including beginners) to use, your and P-A's approach is more fool-proof.
But it doesn't mean it has to be the best implementation, don't give me that cheap talk.
Remember, I didn't criticize your (or P-A's) amp, I haven't heard it, I was just defending myself by your senseless attacks, you seam to follow me around.
And lately you are threadjacking everywhere.
I have my experiences with these chips and I can predict if it's a good implementation, if it will sound good. Because I did try many things.
But I keep those thoughts to myself, I don't post like you, I don't attack like you, I don't treat other members as a bunch of amateurs.
If you have constructive things to say, you are always welcome.
Otherwise you are not, and I will always reply to your stupid and unapropriate insinuations.

Don't expect too much from me.peranders said:
My system is not that good, so my comments will be valid only for my system. I will mention this again when I'll post the results.
So... back to upupa epops...
He talks about his amps and how great they sound. I wonder tho, what cables does he use? What preamp/source? And much more important, what speakers?
If he has one of the best systems in the world to test the amps with, he would have a valid point. I doubt he has some of the best, so I bet he can't be right.
It would be clear why he positions the chip amps in the "children" class if he has some low SPL speakers, or if he uses some high capacitance(or L or R) speaker cables. Would be nice if everybody could tell what's the best amp just by using any system, but the things don't go like this. And amp is just part of the system, and you need much more than a good amp to have good sound.

To roibm : I never said which ones will be better, read my words attentionaly. I was compare this ( my ) amp against several discrete types and I must say, that this one wasn't winner and I don't belive, that any miracle connection can't change it - chip have own quailitative limits. Many other amps are worse and I belive, that to many guys sound of this amp is realy surprise, 'cos are accustomed for these commercial " lemons ". When I read here only comparision with some commercial products, have it for me only " low weight ". I can't take to others enthusiasm, I say again that it is good product, but not miracle. You are calling me mockeryly Great-know-it-all and many guys maybe agree, but I mean all it honestly and more to lead guys to thinking about it.
Upupa Epops said:
Upupa, no more fights, please.
Just understand one thing:
When you call every commercial amp a "lemon", that's not pretty.
It makes it sound as your amps are the best thing on earth.
Besides, you are only generalizing.
You can listen to a Lavardin IT, like this:

I post this link, but forget the commercial talk from the manufacturer.
Just listen.
