Help with diode choice problem please

Rectifiers NEVER effect the sound. Simples.

I translate: he wanted to say that he can't hear the differences diodes could cause (and do cause for that matter).

Everybody can compare a Naim style rectifier to the more common bridge rectifier: it will make a difference, in many cases a not so small...

(see here for diagrams)

Perhaps he wanted to say if an amplifier is halfway to decent the choice of rectifier diodes won’taffect the sound, if they do there is something fundamentally wrong with the design.
 
It's a pity that that experts like myself have to waste so much time correcting the bollox talked by those like jpk who don't know their arse from their elbow on technical matters at the end of the day but no, I said precisely what I wanted to say.
 
I am a diy amateur, correct, and in many cases do not understand why something sounds different, also correct. But I know what I hear. BTW there are simple technical explanations why the mentioned diode configurations do sound different: you as a pro should know them.

Same for all other of your claims which you take your time to spread all over the forum such as a resistor can't sound different, a cable can't sound different, etc. etc.

At least you should make clear it's your personal opinion, based on the fact that you can't hear the difference.

You spread a lot of bollox as well (did I spell it correctly? I learnt that word from you:) ), and exactly this type of ignorance is what the world needs the least.

Finally you should lern to respect and tolerate other opinions and stop just bashing against anything you don't get.

But that's just my personal opinion :cool:
 
Your opinion on electronics is worth about as much as mine on brain surgery... but I don't go around trying to tell surgeons where they're getting it wrong:rolleyes:

If you knew enough for your opinions to be taken seriously you wouldn't need to keep asking beginners level questions in the DIY area... and basic knowledge such as the outer foil being identified on certain types of capacitors would not be a revelation to you.
 
And you are the one who judges how much my opinion is worth...? :D:p

Like so often you don't answer on what was said, instead you come with new claims...

jpk is a DIY amateur and does not deserve to be spoken of and insulted in this arrogant manner. If this is going to become a more frequent way of behaving on this Forum then I'll be looking elsewhere. Shame on you Jez.

I see it in precisely the opposite way to you! Yes he's an amateur and not a particularly knowledgeable one and he has the cheek and disrespect to try and tell a pro of over 40 years experience "how things are" when he doesn't even understand the basics, and after I'd took the time to try and help him... several times.

Day after day it's like watching people who've just passed their driving test and got their first car queuing up to try and tell a pro automotive engineer how they should be going about fitting an oil filter and that they've been doing it wrong for the past 40 years!

TBH I'm getting so sick of idiots who've read "The Ladybird Book of Electronics" or seen a video on youtube thinking they now have the knowledge to challenge the professional opinion of actual engineers (and even the laws of physics!) that I'm giving serious consideration to only giving technical advice and help to paying customers and via PM in future.
 
I talked about what I hear, not about what I know (except that I know what I hear :cool: ). On the contrary I admitted several times that I don't have professional knowledge about electronics. But I do have knowledge of music and what can be heard of it through an amp or system. If that is worth nothing, what's the point of the whole audio business...?

In other words: if an amp designer can't hear a difference between Mozart and Haydn (just as an example from the view point of a classical musician) how can he make the amp deliver the music? I have 40 years experience of understanding these composers. I am not joking. I claim the following: there are amps which clearly transport the content of what the composer wanted to express to the listener. And there are amps which do not. I will have a strong opinion on any amp at least in this regard.

Jez, you are the one who raised the discussion about competences, not me. I am as competent in my field as you are in yours. We all should serve the music, at best as we can. So please stop fighting!

BTW I highly regard your opinions on brain surgery :D
 
Oh dear
I did not want a simple advice thread to degenerate into a slanging match:(

I really appreciate ALL the advice you kind people have taken the trouble to put down for me

I really hope everyone will continue to do so ..both for me and others ...it's what makes Pink fish sure a great forum.

Please don't make me have to ask for this thread to be locked....let's just leave it there and all move on:)

Thanks again everyone

Tim

I play half a dozen instruments myself, not very well! How would you feel if I said I'd read "The readers digest guide to the concerto" and I then posted on a public forum that as you don't agree with me, on your own specialist subject, you obviously DON'T in fact know the difference between Haydn and Mozart?? Get my drift?

I'm very happy for peace and harmony to reign:) but if you want to tell me how to do my job then at least wait until you've got to the stage of having actually designed a few amplifiers first:)

Says the man who asked for and was given the schematics and PCB design for an amplifier and didn’t say “thank you”, glass houses and all that.

Well if that is indeed the case Russel then I humbly apologise, I really wasn't aware that I had done that. Kindly fill me in on the details my misdemeanour.

I don't really see how that excuses Arkless's insulting and arrogant manner though.
 
Hi Russel,

I do indeed owe you a public apology and here it is. I checked back through my emails to 27th August 2014 and found two emails flagged red for a response from me, which never came. I suspect it was something to do with my Heart Op which was that same week. I now have a pacemaker!

Sorry

John

Perfectly reasonable excuse for forgetting to reply, best of luck with your health, no need for apologies!
