D7 Sidewinder....Initial impressions - Page 26

post #376 of 671

My USB port is noisy with my D7 - I have a POWERED USB hub on order to try to eliminate it.  It was much quieter on my laptop.

 

UPDATE - powered USB hub solved the problem.  D7 is quiet now.

I experience a very slight his that isn't noticeable until about 12 o'clock on the pot.  That's only with the music off so it's very rare that I hear it at all with the music playing.

Has anyone tried listening to music through the line-out? Is that what +0 dB of amplification sounds like? If so, I like it... For me, it's completely hiss free, and even at 100% volume, it's still a volume I can listen at. To my ears, it's as close to being free of color as I can imagine something to be...

My D7 just arrived and everything is up and running :D. Also I don't get any noticable hissing unless I am at 1-2 o'clock but still pretty faint.

 Congrats and enjoy!

Greetings,

 

I also recently received my D7 and noticed that, as several posters have mentioned, the sound improves significantly with "burn-in" - the instruments and voices become more substantial and there is more "air" between the musicians.

 

Unfortunately, I am also experiencing the USB error message - which, while I understand does not affect usage - ultimately does not promote confidence (if ibasso is aware of this issue shouldn't it be resolved?). It gives the impression of oversight and an unfinished quality to the product.

 

Lastly, and the main reason i am writing - I connected the d7 to my imac (2.66 ghz i5; 4gb; osx10.6.8) as well as my old macbook (similar specs) and tried to use the integer mode of audirvana to no avail. The red CPU usage alert would flash incessantly, resulting in distorted playback. the preference setting is selected to XMOS USB audio 2.0, hog mode, integer mode, max i/o buffer (and I even tried different combinations of these)

 

I posted a query on this thread regarding integer mode and the d7 and the responses seemed to be favorable so I am wondering if there is an issue w/hardware or software that i am unaware of ...

 

Any ideas or similar experiences? advice?

 

 

thanks!

This device has got so many things on it (Class A amp, XMOS USB receiver, Wolfson DAC) and yet is being powered by only a 5v USB power. It is already a magnificent feat. I am not sure why the error message appear on Mac but it doesn't affect anything.

 

I could use integer mode on my Audirvana Plus. The Red CPU usage alert would be a result of upsampling. Integer mode will not consume CPU, it is a either 'Yes' or 'No'.

this problem more likely on the iOS it self as windows and linux doesnt seem to have it. so unless apple patch it or if somehow Ibasso can make a driver for macs, most likely it will stay.

 

though I would like to ask if all mac user experience this error? if not, it could be just a matter of setting the OS itself.

I am really in love with the line out of the D7. My earphones are driven to a perfectly good volume, and the sound is possibly the cleanest I've ever heard in any sub-$500 product, with more details than I can ever hope for. Imaging is also absolutely stellar, as with bass control, since nothing is boosted. It also doesn't have that slight warm skew of the headphone output, nor does it pick up my computer noise. It is dead quiet. Yes, I can't adjust the volume, but I don't need to.

Just out of curiosity, how well could the D7 drive an upper echelon headphone like the LCD-2 or the HE-500?

really bizarre - i just tried it again and am able to access integer mode ...

 

thanks for the feedback,

happy listening.

Ibasso emailed tracking # this morning, won't be long now!

I wanted to update those of you that may be having some background noise with your D7's.  I purchased an inexpensive Rosewill powered USB hub from NewEgg (link here) and it has completely cleaned up the background noise on my D7!
 
All my noise problems are gone now.  This is definately a good suggestion for anyone with this problem.

Anyone had success installing D7 drivers on Win XP system?

 

I tried it with different Thesycon drivers (from Cambridge Audio, Ayre etc.) but the D7 gets no USB link.

 

With Vista or Win 7 it runs perfect. Easiest connection was with Ubuntu. Plug and play at it's best!

 

I had contact to Thesycon and they said that iBasso uses a very old driver version and that the driver isn't fitted to the device. It's the version from the XMOS evaluation package!

 

I think iBasso is a 2-people firm with no software specialists. Just plug and pray! normal_smile%20.gif

so did they(thesycon) have the new driver? considering the other maker driver also cant make d7 work on your xp, and i think the driver is only basic usb audio class 2 driver.
