I thought you said using opamps meant you were using an appnote? Now you are confusing me. I also thought you said opamps sound like garbage... why are you making a garbage DAC for DIYers (your definition, not mine)? Sounds hypocritical.


No, I do not think I said that op-amps sound like garbage. I said that you newer will reach maximum performance using op-amps. But also, that you newer really will fail.
It's like buying a toyota. It will newer fail and most of them will run OK. But you will NEWER get that BMW driving feeling.

If you read what I say, the 32 bit DAC we will launch, will be far less complex, and NOT aim as high as the current DAC. The main goal is NOT to make the best DAC ever made... More like... making a cheap DAC that will kick *** to most mid-priced DAC's... let's say under $2k. Our target price is $299. The goal is value for money!

By using an op-amp, we can finish this DAC faster, and know from the beginning how it will sound, in general.
The special feature is a NON FEEDBACK option, still using an op-amp. Guess you do not see that every day ;)
 
Hurtig; post #361: "Our target is 299USD... But no guarantee!".

I do not get your point, but I know that you hoped to find something bad about us... Bust sorry. We will NOT sell this DAC!!!!!!!!! Is it really that hard for you to understand??????????

Our target price is for the total BOM including PCB, transformers and all components. This meaning that DIY'ers can order the parts from Digikey and a PCB supplier themself, and still get it all for less than 299 USD.

Please.... before you search for something else to discuss, tell me what kind of problem you see in this.
If you just keep on searching for new issues, you quite clearly show, that your only intend is to start some trouble.
 
Shush! They want to offer a commercial product in the members forum's, as they have zero advertising to pay for don't you know. Why buy a Vendor's Forum spot, when they can advertise here for free :spin:

Clearly you have the same malfunction as NicMac.... You simply do not understand.
We will NOT sell this DAC at 299 USD.

The target of 299 USD is for the complete BOM including PCB and all components.
We will most likely upload a complete Digikey BOM, so that everybode can order themself. Also Gerber will be public, so that you can order the PCB yourself.
And yeap... The Target is 299 USD, and this will NOT involve buying anything from us.

If you still have problems understanding this, I'm sorry to say, that I have to give up on you. Keep up the good work :D
 
Kurt you and your partner must stop your poor attitude here, and stop attacking other products in an obvious effort to promote your own. We don't like members with aggressive attitudes and they tend to not last long..
This is an official moderator notice.

I agree.... and will do.

Then please tell me, why you have NOT reacted on the fact, that a group of users in here, is not only attacking some products. They are directly attacking Kurt von Kubik and me, with their constant accusations of us trying to promote a commercial. Even though some no brainers have a hard time understanding, we really are not trying to promote a commercial product. We just had 12 PCB's left from our DIY project, that we agreed to let other users have. Just like when others arrange a group buy.

Please let me know, if it is OK if Kurt von Kubik and me starts accusing a few people of almost anything we can ever imagine??? If not, you should consider reacting on those doing this to us :)

I found an actual listening impression of the DAC on a Danish forum. It is in Danish but if anybody is really interested I will will be happy to post a translation.
http://nerds.dk/?forum=viewtopic&p=81334&highlight=#81334

Ha ha ha..... You just blew your cover!! I don't know if you remember, but you seem to be italian. And now you found a danish forum about our DAC, all written in Danish. Wow!! Did you install a Danish language pack into your head :confused:
Or.... Do you just happen to be someone else... :D

BTW... did you know that a danish audio manufacturer went to the court, because they were selling a 120 watt amplifier, only capable of delivering somewhere between 9 and 12 watts. They even got the court to sign that fact, along with the fact that they tried to bribe the independent valuer appointet by the the court... Heard about that company too ??:D:D:D:D:D:D:D

Hi Hurtig

Being a little to fast?

If you think NicMac is the one who asked the question on the danish site, you are very, very wrong - I'm the one to blame.
But I'm also guilty in sending the link to NicMac as I know he would be interested and don't participate on danish hifi-site despite he (also) speaks danish.

And yes this is my first post on this forum. And no, this profile were not made for the occasion - It's more than five years old!

The saddest 1. post on the hole site - sorry to you all

Just type "Hurtig" and "DAC" into Google and it's the 5th hit down on the first page. Duh.
 
While we wait for NicMac to come with a translation of from the Nerds page, I have taken the liberty of translate it. I should mention that the user ”Janils” is a wellknown danish audioreviewer from the magazine ”High Fidelity”. He has been a reviewer for more than 15 years, is very respected, also for his behaviour on the Danish audio forums, where he always is honest and very polite. So the writing he made on the Nerds forum is definitely unusual from him. He wrote:

No it does not get into High Fidelity (Translators note: he refered to the previous post, where a writer asked him if he would write about the Kurt Von Kubik Dac in High Fidelity).

From Greater Copenhagen HiFi Klub was 10 men on visit at Gryphon Audio. After this fantastic experience, we went by Kurt Von Kubik. Brave to invite us, and we was well received.

Kurt is not here, so he cannot reply (Translators note: Kurt Von Kubik is kicked out of the Nerds forum due to his behaviour). I will therefore moderate my statement. It is a fine little DAC they have made. It is smooth and neutral. At a price of 6000 to 8000 kroner it will be a good purchase. (Translators note: this is equivalent of the pricerange: 1171 to 1562 USD).

But can you evaluate “the worlds best” over a pair of small Dali speakers ? They where connected to a relative large (enormous) Klass A amp (where the ventilators made a little noise) (Translators note: this remark must be because of a debate in Denmark about the amps noise, since the german magazine Audio measured the signal to noise ratio to 65db). But when the good Kubik headstrong talks negative about both Accuphase and EMM as some “junk” that is faulty constructed and after that calls the Audio Note DAC (heavily modified) we brought with us as totally wrong, and impossible to listen to – yes, then my chain fell off. The Audio Note converter played music – The Worlds Best DAC played signals, clear and nice, but completely without the soul and warmt there can be in the music.

It was only mine (and others) politeness stopped us from loosing out temper. It is OK to believe in ones own product, but from there and to not accept criticism at all, there is far.

What got my pee boiling was as an example, when we played an good old 60es version of the magic flute. Kurt rejected it as useless, since the music already distorted and was imbearable to listen too. He then took a never version of the same music and played that. Gone was the charm, the life and people of flesh and blood. But yes – it was clean, nice and totally without charm.

I can only say, as one of my good friends so correctly expressed it “engineering pop”.

As an answer to the tread starter – what about the Cambridge DAC magic (there is several treats about it on this site).

Sure, I'm interested.
As I understand the poster was present at the audition at KvK's place. He states that his comments are "moderated" as KvK is not present at the forum to reply back (I don't know why). I have only translated the parts directly related to the quality of the DAC.

"It is a nice little DAC they have made. Smooth and neutral. A good buy for around a 1000$".
At the audition the DAC is compared with a heavily modified Audio Note DAC. The poster say that: "the Audio Note play music while the "Worlds best DAC" play signals. Nice and clean but completely without the soul and warmth present in music.

Concludes by describing the DAC as "engineerpop".

Hertig,
You and Kurt started this argumentative and and aggressive style here. Now other members are giving it back to you. Kurt von Kubik is in the Sinbin for 4 days. I hope that both of you aren't going to have to leave our forums as you have had to leave another

To all the other posters:

Let's stop the arguments here. I think we have a clear picture now, and should revert to appropriate behavior for our forum.

Thanks,

Mark

Nice to see a totally new profile beeing som enthusiastic in this old thread. Can't even imagine what your old profile name was :D:D:D
Could you do us the honor, and tell us who you really are??


About the "review" by Janils, I am very disappointed. I did NOT hear Janils or any of the other 9 guys saying anything like that at all. Janils critizises the DALI speakers used in the listening test at the forum. But during the test he was nothing but ULTRA impressed about these exact speakers. Yes, Janils did prefer the old AN DAC, which I do not understand. My best guess is, that he will also prefer an old Linsley Hood amp over the DALI Gravity amp, because of the single ended sound. Guess we just do not agree on music.
Besides that, NO ONE of the other 9 people visiting us chose the AN as the best, as all of them were very impressed over the sound at "casa di Kurt von Kubik".

I have only few ideas, why Janils suddently decides to post such a review. Maybe he just needs to, in order to justify the fact, that he paid big bucks for his own EMM DAC :p

I honestly hope, that some of the other guys present at the listening test, will join this thread, and give us the real story.

And now.... back to reality!

Any inputs on how to make a 32 bit DAC??? As you know, we are planning to.
Any suggestions will be taken into consideration ==> There may be a good chance of making a DAC, that will honor the requirements of the DIY'ers.

We have something like CS8416, CS8421 and AK4399 in mind.

Jan Nielsen said he (and the other) was very close to loose his temper during the audition, so maybee the guys are just polite when visiting Kurt Von Kubik. Anyway, if the other visitors do not agree with Jan, you will probably see them post rejections on the Nerds page.

The point is probably as Jan said, that it is ok to be proud of your DAC, but the worlds 8 wonder, its definitely not, despite your enthusiasm.

I am sorry if the posting of the diagram was a break of rules in here. However you have numberous times said you would post it, so now it is here, and we now have a constructive topic for debate, namely the diagram.
