and this?

i got the feeling that it maybe an encoder/decoder issue for the difference between flac level 5 and uncompressed
 

 

 

in any case do a bit comparison test between the original cda in the CD and the produced flac (uncompressed) and between the flac uncompressed and the flace level 5 compressed. they all must be bit-identical to each other. when this is done use the madflac for decoder which does a bit decoding process

 

and then do an abx test using madflac

I used dBpoweramp to rip my CD. I ripped it in both formats and it was confirmed accurate with AccurateRip. I did an ABX test in Foobar and I could guess which was which 9/10 times. I know they are completely the same and theoretically they have to have the same sound quality. But for some reason, I hear a difference.

have you compensated for this?

"True bit perfect playback is sending the audio file unaltered to the audio device.
Bit depth, sample rate, number of channels and the format should remain unaltered."

-- http://www.thewelltemperedcomputer.com/KB/BitPerfect.htm

 

Any digital volume attenuation would result in "non bit-perfect playback".

 

 

 

How to obtain bit perfect playback

This is a matter of disabling all DSP in your media player.
Configure the audio of your operating system right to avoid e.g. sample rate conversion.
Choosing the right drivers like WASAPI or ASIO.

See the Operating Systems section for more details.

Testing bit perfect playback

Either you believe you have your configured your system right or you proof it.
This can be done by playing a file.
Record the digital out of your sound device.
Load both the original and the recorded file in an audio editor.
Time align (crucial, they must start with the same sample at the same time)
Subtract the tracks.
If  you don’t  end up  all samples being zero, there is a difference so the recording is not bit perfect.

This is called the null test.

How many bits do you hear?

Even if you have bit perfect playback this does not necessarily means you hear them all.
DACs do differ in their ability to resolve the bits.
Some cannot even resolve all the 16 bits, some might go as far as 22.
This is called the linearity of a DAC.

anyway if we continue pressing on this we will reach the realm of insanity tongue.gif

Is it possible that the difference heard in between compressed and uncompressed lossless could be due to the decompression/decoding process hitting a bottleneck or bug somewhere in the system or software?
post #9395 of 27140

if you do a bit comparison between flac compressed and uncompressed files on your hard drive and they are identical the only explanation for the difference 7S Cameron hears in the ABX test is due to the decoding/playback process.
 

 

 

 

WTF AM I SAYING???

 

 

they cannot be bit identical due to the reduced file size of the compression process!!!

 

 

what you have to do is to decompress the compressed and then check if its bit identical to the uncompressed. That way you can verify that the compression/decompression process through the software yields same results

 

and then its only the playback issue. You have to bypass windows and send the audio unmodified from the pc to the speakers/headphones dac or use the sound card dac directly

i dont remember who posted about the corecool v'2 dual driver iem.... but these seem like the same ones but without the detachable cable.  and its 24+shipping from woot

One question.

I'm confused: my xb90ex sounds pretty much like the fxz200!

What's your experience between these two?

post #9399 of 27140

So, after having to deal with my (un)friendly post office for about 30 minutes, someone finally went and dug my package up and I got my H-200 today!! ksc75smile.gif

 

First thing first: one of most impressive packages I've ever seen earphones come in. And the box is heavy! It's not wood, but a beautiful box nonetheless that screams quality and that there is something special within the box. 

 

The earphones are beautiful to the eye with a nice feel to the cord and IEMs themselves. I only got about five minutes listening time with the stock tips already on the IEMs, but I'm quite impressed with the sound. Basically what Flysweep and others have stated is point on. A neutral sounding IEM, but that doesn't mean bass (sub-bass) impact is not there. It is. Plus I'm a believer of burn-in, so that should open up the dynamic bass driver after some hours of burn-in. Notes have a nice weight to them. The GRO7 (original) sounds a bit thin and 2-D to me in comparison. That's it for now, but out of the box I'm quite impressed. I will take it in some more on my way home (happen to have my CKS1000 - my favorite universal at the moment, so I'm interested in how these two stack up against each other). 

 

More impressions to come. Oh, I can say with my brief listen that at limited $200 sale price these IEMs punch way above the price. This is a very good sounding three-driver hybrid IEM.

you mean you have both and both sound almost identical?

As I said in the H-200 thread, I'm very interested in your impressions - looking forward to them!

 

You asked earlier what tips I'm using on the 1k's, and auvio double flanged tips are doing a stellar job for me :)

Hmm, still not sure whether to get the Carbo Bassos or something else (CKS1000 maybe? Good for bassheads?)

post #9404 of 27140
Ok my eBay mate got a listing set up for 3 Zero Audio DX200 Carbo Tenore earphones.

Who's still up for a group buy?
