Topping PA5 (TPA325X) : Is a modification worth it? ?

[bucks bunny]

Sorry but I cannot discover any contribution to DIY by you. And your claims to be that super-dupa audio guru are not entertaining at all.

 

[Amplifier dude]

Thanks for your contribution. You’ve added great value to the thread.

Hey, Dude - i think you should tune down your marketing here as you clearly are running a merchandise business. Or post in the Commercial sector when you feel a strong urge to hawk your own wares. If I recall correctly, its a forum rule actually...

I’m not selling anything. You guys asked some questions so I answered. As I recall you asked:

“please say something more about your DACs...”

 

[Amplifier dude]

Not sure why the hell you think I would come here to sell $500000+ immersive sound theatre systems. Because the kinds of folks who mod $300 amps are the target market for such a system?

 

[TNT]

So why are you telling us in the first place?

//

 

[Amplifier dude]

Because people asked. Why does anyone come on here to discuss audio gear?

 

[TNT]

Here we discuss DIY. Mostly anyways... so when a professional participates, it requires some tinking why one would be here...

Lots of industry professionals are on here. So is there a knowledge ceiling requirement for the forum? If you exceed a certain qualification, you can’t be here?

I for one am quite interested in this new creation. So your integrating a DAC on a Purifi board?

 

[Amplifier dude]

Sorry wrong thread for this conversation. Clearly some are offended by excellence in engineering.

 

[PMA]

Certainly not an educational forum. Over there they’re taught that you just need to know 1 number to know what’s best. Keep it simple, this way you attract simple minded people.

Though it may sound a bit harsh, I agree. I have a big problem with this single parameter comparative measure, at ASR. Trying to explain what I can but it does not help much. Those who know they know and do not need explanations. Those who have no background and are not willing to study and learn are lost cases. Unfortunately, as the internet has become accessible to very wide public, the latter group heavily prevails. It was a bit different, 20 years ago.

The designer of the PA5 has now stated that it is not a TPA chip in the amp...

[mamocel]

Au vu des spécifications, cela ne m'étonnerait pas...
puce infineon peut-être?

 

[TNT]

English please...

[mamocel]

Sorry.....
In view of the specifications, that wouldn't surprise me ...
infineon chip maybe?

 

[KSTR]

Amp has been opened, heatsink removed, chip clearly identified by its top marking, buried deep somewhere in the ASR thread.

The chip they used in not the key thing, the implementation details are, and Topping isn't using anything you'll find directly in the datasheets and application notes.

He talked about chips under a cover and a new way to reduce distortion, his patent.

 

[daniboun]

Il a parlé de puces sous couverture et d'un nouveau moyen de réduire la distorsion, son brevet.

Right the only secret are the op amps in the D01 small box. I was thinking about differential op amps....
