Accidentally discovered information regarding aptX HD. Not everyone might be interested in this thread, then under the spoiler.

In May last year the Korean company Radsone, being Qualcomm pratnerom in Bluetooth 24bit Audio design prepared for their participation in the exhibition "Munich High End show" confidential report, which revealed a monstrous lie on the characteristics of Bluetooth 24bit Audio technology advances today, Qualcomm-ohm, manufacturers and LG in particular, on the market.

In a nutshell - for encoding music in aptX HD on the side of the transmitting device responds software executable on kvalkomovskih Protsakh. For decoding aptX HD host devices only respond to the market today kvalkomovsky chip CSR8675, which according to the specification of processes and outputs on a mountain 24-bit audio.

It was found in CSR8675 after DSP chip is a 16-bit DAC, which lowers the decoded DSP 24-bit stream to 16-bit sound giving as in a conventional CD.

That is, none of HayReza air there today! : Wallbash:

Radsone suggested that its decision-crutch, allowing to obtain true-to 24-bit sound in the headphones, etc.. Devices.
They developed their circuitry, which originates from the DSP CSR8675 24-bit digital stream and bypass the built-in chip 16-bit DAC output it to your external 24-bit DAC, besides adding to the board also your timing chip, as integrated into the chip CSR8675 quartz still has a strong jitter!

In general, change change, marketers have raped again by the most Nimaga: D
I'm not saying that just do not need to buy and use these pseudo 24-bit headphones. They are still somewhat superior to predecessors, but to know the truth is always better than to dwell in illusions.

But in the near future, new coils vyachivaniya money will certainly await us through new aptX HD + aptX QHD aptX QHD + ...

Here it isRadsone documentwhere you can read all the details.

Unless it is a pale and not a fake! Because well, very much rough namarketili.

Read the last pages and 30 and a couple of questions arise, the answers do not really find it.

1. How do I know a good Hi-Fi sound in the katabatic player (yes, there are 703 PowerAmp alpha, but it is likely dead because this status already since April 2016)?
2. What is the volume of the headphones earplugs to 50 ohms? It is very low? I just have a Maze Pro 5, and it sounds fine with me, I wonder whether the much quieter LG. I'm not an audiophile and me is more important than volume.

Well, "deaf" is a relative concept, most feature phones listening to music in the VC and the volume it with enough margin, and from the maximum they say that "deaf". Here is the schedule where the volume which the laboratory laid out, there is relatively low. Well, 40% of it is nothing at all, and now specifically included in the Maze 40%, only in a sound-proof room, you can listen to this volume, and it will be a desire to add more) What can we say about the noisy street.

I think this is misleading. How many I did not try to tell the difference between the player alpha drain PA, only occasionally, only to hayrezah specialized discs for testing the headphones I think I hear it seems to be.

IMHO, much more important than the player with its capabilities is the quality of mastering the material, which then someone was merged with vinyl 24/192.

kara puz @ 27.02.17, 15:00*

This is not the volume percentages and scale division, which has a V20 75 :)
Accordingly, 75 = 100%
Or how?

MoXoB , Then something like this - if the high-resistance ears include additional reinforcement in the chip DAC and comfortable volume is, for example at the level of 50 units. scale, if you disable this gain slider is necessary to increase the volume up to 70 units. to reach the same level.

And do not forget that the acute shortage of the volume on the low-resistance ears always have a backup plan to deceive the DAC substituting it with the emulator adapter high resistance. After switching on the DAC-th mode of high-resistance, the emulator is pulled out from the adapter and any low-resistance stuck in his ears: good:

On Maisie example is not confusing, but there is enough to register the name of the player in a special file whose name ends and everything is OK will be. And without this amp is not involved in the volume of any third-party players. That's interesting as this in skiing. I understand the DAC and amplifier are different things, responsible for the quality of the DAC and amp volume seems interested in my case, an amplifier, because unlikely I notice the difference in the sound, but I note in volume)

all believe that the mind is unusual and should be from 0 to 100, and ski at the 75% cut. but in fact it is not clear. what could I do such a scale up to 75? still in increments of 5, do not be 25 more steps to add?

Correctly understand! And as far as I understand it - and DAC and amp is integrated into a single chip. And yet - all the more inclined to think that the high-resistance mode still includes only extra. gain, but no it is not the three additional modules the DAC, as reported by the official doctrine of LG. In any case, to determine the ear that runs one of the four modules or anything I did not get.

kara puz , You have a lot of experience and the ability to create a beautiful theme. I ask, and you will be able to decide whether to help with this - we need a sub-section "All aspects of the sound LG V20". What we could out there calmly discuss all these aspects without cluttering up the main section: blush:

Continuing study of the question - how to get the rub-hayrez 24bit sound of the V20 "over the air" came across an interesting device from Astell & Kern calledAK XB10price of just $ 189 o.O

This little round box allows you to connect any headphones with V20 via bluetooth using the codec aptx HD.

My attention was drawn to one distinguishing feature - unlike aptx HD collars from LG, where all audio processing cycle takes place in a single chip CSR8675 and at the end of the path 24bit sound is converted to 16bit, Astell & Kern engineers did not dissemble, and in addition to the bluetooth module and DSP chip CSR8675 establish normal "decent" DAC Cirrus Logic CS4350, which not only saves 24-bit technology, but also has a built-in PLL clock generator, carefully related to jitter. Well amplifier capable of high resistance to rock ears are not forgotten, of course.

Surprising the fact that a modern solution "all in one" CSR8675, which onlyIt begins to be advertised everywherethis year and costs about $ 10 in retail who do not want to compromise the developers of the Astell & Kern added full DAC sample of 2007, the price of which the ibee $ 8, as a result do not hesitate to ask for its creation almost two hundred bucks: good:
There's probably a very expensive amplifier? I suppose, too, a single-chip?

Well, in general, it is clear, then the margin for the brand and exclusive, just do not have similar solutions.

Avantree in HD is not yet noted but Radsone, who last spring went to Munich to expose Kvalkomovsky DAC seems trying to stir up something yourself. So far, however, in addition torender box called DARthen it is not moved. Promise External Hi-Fi DAC, as well as with AK XB10. Just the price was not similar.

Alfa 704 * (by the way, up to 703 alpha any version on PA V20 sounds disgusting). Here hell knows, I am also a long time tested and have come to the conclusion that the difference between the PA and the drain alpha player NO. The alpha brought support for a variety of hi-res solutions seems relevant for the V20. Another thing is that full support is still Quad DAC not, but if it is in stock player, but the difference between him and the alpha PA there now, the conclusion - the human ear can hardly tell the difference when it appears. Something tells me that the full support of Quad DAC can somehow manifest itself only in the high impedance mode in the respective headphones.

Behind the name Alpha PA disabled nafig stock player application, it is too clumsy and primitive.

difference between Alpha and PA drain NO player
I think this is a very subjective concept, depending primarily on the physiological features of the hearing. On 80 ohm Beyerdinamic Custom Studio I feel the difference very well. Stock generally do not want to use it, so it (for me personally) is dominated by high-frequency (do not clean up the equalizer). RA 703rd alpha.

Yes ... it was my collar the A100, the third day of studying, compare. aptx HD I liked, we can say with confidence, justified hopes. By the very dynamic gag collar A100 has some issues, they sound like is not bad, but a bit as dynamic saundmedzhiki E80, they once bass deeper still and the top a little brighter.

That would be more fitting to listen to HBS-1100 ...

That is, after three days of the study come to what I compare the sound drivers themselves, not paying attention to the fact that the connection is different. I can not hear the difference in principle between a wire with a DAC and aptX HD. Bit causes skepticism and doubt, right? :)

Well, the battery is still eating, but ...
If no music via Bluetooth I usually charge for more than two days missing, then this aptX-th till the evening to live out and be fine.
