[Mooly]

^ Done

Thanks Mooly

sidebar question, after trying the new sine tones test i noticed a lot of noise when moving on screen digital controls such as levels in Windows or the level control in Foobar, should i take that as a sign that my computers supply filtering is going south?

 

[PMA]

I do not think so, it rather looks like Windows drivers are used for the soundcard and they are affected by various SW run. Have you tried to disable all enhancements in Control panel (for the soundcard used), as we discussed in the previous thread?

 

[turk 182]

yeah you gotta remember i'm a digital neanderthal...

a lot of what i'm hearing is "zipper" noise (level shifting) but i also hear high pitched squealing (very low level) that modulates with video screen changes as well. i can't expect to hear low level audio distortion if the supply lines aren't happy, can i?

 

[mjf]

........"internet noise"? (modem or sowhat?)

I heard the same complaint from members at our local forum, it was unrelated to the test signals, they just had this problem in general and usually audible when the music passage had low level. I have not experienced this problem, so I am not able to give an advice, other than I would download and use ASIO or WASAPI drivers for the soundcard, these drivers bypass Windows sound enhancements.

So, by now we have no positive ABX results for the nail/screw test, except for Mooly's 5/8, 6/8, 5/8 trials? On the other hand, sine tests with 3 tones were more successful.

 

[BYRTT]

Okay took me together run the 16 trial test on nail/screw

Post 34 was a 3/8 over diy active speaker.

Post 69 was a 5/8 over HD650 cans.

New HD650 cans test below:

Wow, that's a good result!

 

[BYRTT]

Agree it looks good and much better than expected, i changed my DSP correction profile for HD650 yesterday so they subjective sounds as a million maybe it helped also for these close ABX runs, that DSP is the reason Foobar report JRiver as a 24bit soundcard, will take one more 16 trial test run later to see if i just was lucky this time or what : )

 

[Mooly]

A very good result indeed, and the time stamps show just how long you deliberated each choice.

 

[BYRTT]

New run late last night but still good result or is it some luck test is over DSP corrected HD650 cans and a pretty good Neurochrome HP amp although a wish in future is to upgrade DAC to some new 32bit stuff, where present one is ES9023 based.

16 trials test:

Very good result, twice repeated 10/16!

 

[BYRTT]

Yes 16 trials test twice repeated although not that its easy test but seems new head phone DSP corrected setup works bit better than old head phone setups DSP corrected or not or any speakers.

Could you not download the zip file straight from the dropbox page without using dropbox? I've only listened so far on my chromebook and Grado headphones, I will try again tomorrow and listen through my stereo

I listened through my speakers and could hear the double thump again at 58s, probably a combination of knowing it was there and that I have damn good OB bass speakers

 

[craigtone]

No fancy software ... just listening on iTunes via Marsh HA and ATH-M50x cans.

Nail is the original

Screw is my favorite ... I enjoy the fullness of the added harmonic content.

Thank you for your comments on sound - let's see in a couple of days.

This poll will close on 29th December 2018 at 09:59 AM

I don't remember in which thread it was discussed that H2 is important for acoustic instruments. Also, violins have rich harmonics that when we lost them the sound will be less enjoyable.

In case you mean added H2, added distortion in sound reproduction is important, then it is a nonsense.
