From another thread, you say:
"I'm not sure if p2p has that much of advantage comparing to well designed board. It's certainly safer for some people to do p2p than work with badly designed pcb. I don't know if Frred's board is ..."
I am confused... very much... Why you say like these within days?

I will offer a few possibilities:
1) not careful in composing one's sentences. some of the times.
2) forgetting about what one said earlier. all the time;
3) genuinely confused. all the time;
4) ulter nonsense. at least some of the times.
5) all of the above.

good night.
Variac,
Fred is definitely an acquired taste, like escargots or tripe or guinnes but once you see the grand scheme of what he's trying to accomplish he's pretty hard not to get hooked. I know I used to dislike him alot more than you do now. I have changed. I think in the end he proved to be correct about alot of things.

Peter,
A well laid out point to point is probably the best if the circuit is not too complex and you can design it not to short out when moved. 😉
The differences become smaller with SMD's and now that there is low capacitance solder mask..................who knows? The advantages of point to point are diminishing and there is the groundplane issue.
I am working on a new current feedback power amp and one of the tests I want to peform is lifitng the front off the pcb and wire it point to point and check for differences.
I think you should revisit the A75 and see if you can improve upon it...........just a suggestion.😉
Chris,

I knew this question will come up😉
The answer is simple, to design well a PCB one has to make quite a few versions and compare. It is just too time and resources consuming. That's why p2p, simplicity at it's best 😉
Although I might think that my A-75 board is good, I didn't compare it to anything else, so I can only think.
I also said: "... that much of advantage". It doesn't mean no advantage at all.
I should add that "what I say may not be understood by everyone, that is, if you understand what I'm on about, you probably don't need to be told anyway...."😉

What gives you impression that I think nice boards are good designs? I only said that i'ts nice looking, I didn't say it's a good design.
I believe that my DAC board, although not good looking is a good design. Do I make myself clear?
On a second thought, what makes you think that a good design cannot also look nice?
Boy you guy go on & on & on... i go away for a weekend and you guys are fighting over ghosts...
Halo is welcome back -- he only has to abide by the copyright guidlines (that was only the only issue ever), he has not so agreed
Mr Jung i know not...
Fred asked us to retire his membership... i told him i would be happy to reinstate him whenever he wanted (althou given he has an aol email account there is no telling whether he actually is getting his mail). He asked us to do it quietly, so until now we have not mentioned why Fred is retired, and i won't say more in respect to his wishes.
As to the thread that went to Texas, it was Fred who reported it, and asked us to do something about it, so we moved it... no conspiracy at all.
The guiding rule for mods is do as little as possible... as SY has pointed out many a time, we are more akinn to janitors, than to police.

Dear Peter Daniel
Here in diyAudio exist many experts about electronics. They have excellent knowledge. Meanwhile, I am not an electrician. I know some of physics, mathematics and structural strength engineering. Regarding the electronics, I know somewhat on hobbyist level. Therefore, I often make my errors in my understanding of electronics. Whenever I have such errors, many experts here in diyAudio correct me and I learn lot from them and I appreciate their advices very much. That is why I like this diyAudio.
You have a great self-confidence in your thinking whenever you talk about electrical circuits. But, I feel that actually you do not know even not so much as I do. You are however clever in covering your knowledge using your sweet words and thin ears. You are too much relying on the sweet words and thin ears, and try to stand out.
Please, do not receive this comment as I offend you.
Ultimate target of diyAudio guys might be to pursue the best sound from their diy-amps, and nothing else. Nevertheless, in my opinion, they should not be fooled. Fact is fact. We need to study ourselves to come closer to the truth. You should feel your responsibility with your words, particularly as a maker of commercial products. Sweet words and winking face might be useful in normal conversation or in a drinking bar, but not very much useful in telling the truth.
I hope you will agree with me.
Best Regards
jh6you
Fred asked you to can his own thread? And then presumably "acts" offended by starting another entitled "Since my thread went to Texas"? And then "retires" without despair or moral duress? Yeah right... along with the funny green men at Roswell. Perhaps he was a victim of alien abduction?
I don't buy what you're selling planet10.
Perhaps those WERE the ideals but the numbers of members smelling a stench is growing inversely proportional to the number of intelligent members leaving.
So your janitorial decisionmaking/priorities seem a little poor, eh?

It seems like it is your opinion that I am so wrong, not a fact as you have stated. Yes, you are entitled to your opinion also
It seems like a pretty egotistical thing to have a personal "Grand Scheme" I don't want him to impose his scheme on our forum.
He drives away people that he decides to abuse , and this is arrogant and egotistical. Yes "personality cults" seem to spring up here, and these people get more influence than others, but invariably they are they people that are putting in the effort and are rewarded by appreciation. Of course these people need to be watched to be sure they don't overstep their abilities and knowlege, but as I have said before, he picks targets, then thinks of ways to attack.
Sounds exactly like something Fred would do...
I wonder if his ego will allow him to stay away?

jh6you,
I have to admit that you are very clever with words as well. I mentioned many times that my knowledge of electrical circuits is very limited, and this is not something that I try to hide with sweet words or winking face.
You are quite correct though, that I am very confident in my thinking and in what I'm doing. It does not come from my knowledge of electrical circuit design. It mostly comes from my awarness of what I'm capable of and from what I did so far.
I'm not making any effort into understanding electronics. I learn only what I need, to put a certain design together, and that's about all. That's why I don't have to rely on so called experts. My main strenghts are in mechanical and structural design, and here again, I don't need any particular knowledge. Whatever I create is driven by my imagination, common sense and clever way to use materials. Nothing special to it, really.
I'm not trying to stand out. If you feel that I do, it's only beacause of what you see posted here.
What I don't understand is why some people expect from me to hear some sort of truth. What exactly you mean by that?
Let's try to see what kind of discrepency you found in my posts. Here's the first one:
And here's the second one:
What do you find wrong with those two comments? They certainly don't exclude each other.
Jelousy?
It seems to me that there are the talkers and the do'ers.
The talkers are often the technocrats, with lots to debate. While they are debating the do'ers are achieving.
People are judged mostly on their achievements, and this is right.
The reason that Peter has such a high profile here is not because he was a moderator, or a design engineer, but because he achieves good results. These amps are not the ultimate in what the chip can achieve, but are done in a way that is accessible to almost any member, regardless of experience level.
For those that can do better my request is: Do it 🙂 Show those who've made gainclones by Peter's methods that there is much more that can be done, instead of shouting down his efforts. Give them something to move on to.....if you can.....
Edit: Oops I thought I was on-topic, but of course this thread is off-topic, which makes my on-topic post technically of-topic

Re: Jelousy?
😀
I'm on a completely different path from the "norm":
Power amp:
- Regulated PSU
- Buffered (OPA627) Inverted LM3886
Preamp:
- OPA627+BUF634
This is much better, IMHO and whatever.😀

you are right on. an empty shell, not matter how fancy it is on the outside, remains an empty shell.
Peter and Fred are probably on the two extremes of this: Fred is very knowledgeable, but nasty. Peter doesn't know nearly as much as Fred does (below average in terms of electronic knowledge on this forum, in my view), but has good presentation.
so if you put up with Fred's presentation / approach, you will learn real stuff from him. on the other hand, if you focus on peter's presentation, you will learn his, urh, presentation.
