GUSTARD DAC-A22 (AKI's AK4499EQ AK4499 AK 4499EQ 4499 in use) - who have heard ?

Not open for further replies.
For the record, Jam has no dac or dacs for sale, and I am not involved in any way in Jam's business.
The AK4499 eval board here was down for some modding work so no direct comparison with it. However, we (Jam Somasundram and I) agreed the D90 would need some things fixed to sound as good at midrange and higher frequencies as we think the dac chip is capable of (based on our memory of how good we have heard the modded eval board sound). That said, D90 a remarkably good sounding dac for $700, and it is also the first commercial AK4499 dac we have had a chance to audition. Hopefully there will be some other equally good or better AK4499 dacs before too long. In particular, I am curious to see how good a dac someone can come up with using AK4499.
 
Hello moderation team,
I’m recent member of this forum and enjoy reading through many forum sections. However, there is some (allowed?) behavior of certain members that is leading this forum down the drain, as discussion level is already there.

There are many obsessed attacks on the user Markw4 by member Evenharmonics who is, on any remark of perceived audio quality made by Markw4, demanding measured evidence and detailed methodology by which this is determined. After hundred or so of such posts it’s nothing than harassing.
He is also constantly posting, in any thread where Markw4 posts any comment, that Markw4 is someone’s shill with hidden agenda and so on, without any proof of course. Now he and user syn08 are, without any proof, directly accusing Markw4 as covertly working for some specified audio business. Is this really the norm on this forum and is this place for such claims?

It really makes me sad that valuable contributor to diy audio community as syn08 is not exempt from ugly troll behavior.
All mentioned makes very bad experience of reading certain forum sections, which I am tempted to avoid. DIY audio spirit is completely ruined there, thanks to “efforts” of certain members.

You two guys, don’t bother to respond as I’m not reading anything you post.

I don't have any problems with the way they are behaving. If Mark isn't actually involved with any commercial stuff then that needs to be addressed but what brings this forum down are subjective impressions posted as unequivocal fact and to be honest subjective impressions at all.

I have no room for subjective impressions except as an afterthought and that is after detailed measurements have been provided to show the effects of whatever said person has done, if modifying, or just as an end product.
 
Go for a single AK4499EQ, with this specs one per channel makes not much sense and over complicates the output stage because of the current the DAC outputs.Actually the Topping is great, certainly not worse than a Twisted Pears fully fletched diy dac. I run both ...

This is not true.

You do not sum the currents of the channels when paralleling with the AK4499. You sum the voltage outputs after I/V conversion. Thankfully mind you, no opamp would really cope with two summed channels before I/V conversion.

On the other hand I agree with you about the number of chips used. You aren't going to see any relevant performance increase when using two chips Vs one. The only thing this stands a chance of improving is the SnR, which is already beyond any reasonable reproach when using a single channel.

All using two will do is make the device more expensive.
 
I too am in complete agreement with @tombo56.

(BTW. Welcome tombo56, nice to "see" fresh faces 🙂 )

IMO Evenharmonics is nothing more then a troll and I have him blocked - he brings threads rapidly into decent whenever he posts, and never adds anything of value IMO - I see this as a failing of the forum moderators that have allowed this to continue for so long...

It discourages me to visit / post while these threads are polluted by such trolling.

Couldn't agree more. Evenharmonics relentlessly targets Mark wherever he posts but contributes nothing positive. Tiresome and irrelevant.

I don't have any problems with subjective impressions. Most of us here are experienced enough to treat them as opinions regardless of who is presenting them.

However I do find the obsessive personal attacks rather disturbing. I have to agree with tombo56 that it is really sad when experts such as syn08 need to resort to these tactics.
 
He never brings anything of value to you. What he does is constantly ask people who post subjective impressions to back up their impressions with some sort of scientific rigour. Calling into question their impressions as fallacious. And as virtually no one can ever back up their claims his posts prove their purpose in showing that those impressions are indeed not to be believed.

This is necessary in my opinion because I think people who post lots, and generally, only subjective mumbo jumbo should be banned for trolling. After all, their impressions are erroneous to anyone but the person who made them and are thoroughly misleading in the context of actually building well designed and cost effective products. If you want to read subjective waffle go buy a hifi magazine.

As an example if someone started to post incorrect engineering advice they'd be brought to rights very quickly and rightly so. They'd be perpetuating misinformation. Now if someone starts to post subjective impressions these are, essentially, as helpful as the person posting incorrect engineering advice. They should also be brought to rights and at least have the validity of their claims put into question.

You may not like someone constantly questioning every subjective impression, feeling that it gets tiresome. But I too get sick and tired of people posting subjective impressions. All they ever do is get in the way of people making sensible, well thought out and financially sensible decisions.

Most of us yes. But there are lots of people reading who are not. And in isolation, if the only comments were subjective, there would be nothing else to take meaning from.

For every unsubstantiated subjective claim there needs to be a counter point with someone questioning it.

Personal attacks aside they probably are posting because they want Mark to simply stop making subjective impressions. Either that or back his impressions up in some acceptable way. That's all any of us questioning the subjectivists want. But they never back it up and yet continue spouting nonsense (because without backing it up it is essentially nonsense).

Now people might like reading subjective impressions because they make them feel warm and fuzzy and that makes them feel better about a purchase they are about to make. Sure, that's the way humans work. We want to read something, anything, that confirms or reinforces our choice is a good one. Doesn't make it scientifically valid in any way though, except that it makes you feel better.
 
5th element:
An audio forum is not a laboratory.
It's just a place where people exchange ideas, opinions; by definition this is a subjective thing!
Pick what you find interesting, and ignore what does not appeal to you(r) subjective convictions.
If you, or trolls like Evenharmonics, can't cope with that the solution is simple: avoid forums.

There seem to be different style forums. Some gladly welcome any undocumented impression and strange tweaking. This one seem to be guided to a more objective and scientific stance. So maybe it is in fact a little more laboratory than others. I personally like and value this. Maybe its good that the "market" offer more than one style.

Audio (the reproduction of Music for humans) is inevitably subjective. We are all wasting our time without a subjective assessment at some point. I'm capable of accepting other peoples opinions and will judge their validity on the track record and known experience of the individual but without being offensive I hope.

To be treated as if you are deliberately trying to deceive with no evidence when you present your subjective opinion is unreasonable IMHO.

Not long ago I reminded people in another thread that I sorted single opamp buffers (that were identical except for the opamp used) in order of distortion, and I did it double blind. The recent discussion about that occurred in another dac thread: https://www.diyaudio.com/forums/digital-source/354754-cd-playback-dac-9.html#post6217208
Of course, people that don't want to believe it just pretend it never happened and move on. That's the progress you get for showing proof: NOTHING.
 
I don't have any problems with the way they are behaving.

Do I understand correctly that you have no problem with repeated serious accusation made without any proof or constant obsessed harassing? Jet, those making accusations are insisting on scientific proof of any impression or opinion on perceived sound.
There is no need to again start objective vs. subjective debate.
