Default Post 9 was not for you or because of you Sparkle..it is a generic

advertising, made from time to time....the focus are forum diyers, builders...to invite them to build some.

take the time you need....do not make it in a hurry.

I would like to inform to newcomers, new guys in our forum, that Dx Corporation does not exists in the real world, it is just an idea, alike a club, a group of people that enjoy build and have built Dx amplifiers.

People use to come asking for boards to sell.... we have not boards to sell.... Dx Corporation is not a business for money...it is a business for enjoyment, to have people happy listening nice amplifiers and for free.

regards,

Carlos

Default No discussions dear Wayne...my class A amplifier were mufled

yours not..and that's all.

will not discuss the subject..already told and you are asking wanting discussion.

Thread is about Dx Blame ST, with increased bias to force output to operate class A..this is the thread topic.

regards,

Carlos

Default Sorry to be so short, so direct... this comment was directed to the ones use to build

Dx amplifiers, the "mufled" comment as i use to say that to them... they know what i think about class A as they have asked me to make an class A several times...i said them..increase your output bias as other transistors are already in class A.
they will not understand why i am posting something in class A as this may be an "abomination" in my life..something very strange to happens here..to publish, design, adjust, assemble or anything in class A..i hate heat...if heatsink is hotter than a human fever then it is too much and i increase heatsink or a fan blower is installed.....here is too much hot to class a amplifiers.

I used to build..thousands and thousands amplifiers Wayne...50 years doing that..addicted, sick, crazy for audio... i cannot leave without build..daily..sometimes two each day.... and because of that i have my conclusions...they are based in a very simple sittuation... a non complex analisis.

First build - result - mufled..losses in high end..sound alike below a pillow, or behing a curtain, a clothing material covering the tweeter...loss of brigth.

Second built... result....the same

Third built..... result....the same

After 100 i have concluded.... finally!...that sounded mufled...and as several where operating class A, with different schematics, different designers..then i started to think that class A sounds mufled to my ears, to my taste, in my home, with my musics, in my subjective and personnal evaluation.

I am building.... rigth now, a class A, from NP....because this one i have not build..will not post conclusions, as do not want to bother NP..but i want to know if this one is different..buiding to me, to myself, to check a different schematic never assembled.

What are my spectations?.... mufled of course!...you may say... change your speaker!.... and i did it several times.... i have not assembled yet... spectations only..things will happens near future (explaing in details to no english speaking people alike me...we use to misunderstand very easy)

I accept that others loves class A..reason why i have suggested this one to my dear friend from Croatia..he likes...so...he will enjoy.

regards,

Carlos

Default De nada..you are welcome.... sorry.... i dislike to discuss

as i have made that several times... had created enemies because of that..now a days i am limiting to post my opinions, as i do not like debate... do not want to convince others..i would like them to try amplifiers alike i do.... to assemble and them to evaluate by themselves in the place to leave under the rule of "I think so! ".....so, they will understand what i mean and will not need to argue about things they have perceived too.

Sorry...i was too much short...you deserve more attention, i apologize..too much acid i was with you.

I am ---ing tired of discussions and people trying to give me hard time... really upset with these things.... i am trying to calm down...it is beeing hard as i am mad against some few guys, alike a crab inside a hot can (people use to cook crabes this way...awfull that... alive!)

I am from Rio de Janeiro... a french town, another culture...in Northeast, where i am living now, they cook crabs this way...alive!

regards,

Carlos

Crabs are always cooked live, anyway pretty soon it will be worldcup and another heated debate ...

I ask questions just to get an understanding of what you expect, everyone has different requirements , subjectively you opinion cannot be wrong , we can only agree or disagree .

Many amplifiers sound good and are not Class-A , so subjectively there is no hard or fast rule .
I had asked the question regarding Class-A because some of them have sounded that way to me also. Very smooth, but dark with no energy, yet others have sounded fantastic ! I had never attributed it to being Class-A, so i was interested in hearing your comments on such.

Where is best for listening Audio/Live Music in Brazil, Rio or Sao Paulo? I know they had a high end Hi -FI show in Rio last year. My family friends are from around Puerto Alegre.

I find this video about audio entertaining, best to view when you start to take things 2 serious ...
