D7 Sidewinder....Initial impressions - Page 27

post #391 of 671

I have no idea how big iBasso is, but the use of the stock XMOS driver is something that most designers using this chipset do. Companies also tend to ship with the driver they tested with - even if it's not the latest. If there is a newer one, it'll likely work just fine :-)

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

I am using my D7 on Win XP (SP3) and it works fine.

post #393 of 671

What drivers do you use?

Any hints? Does it work without any problems?

Do you use a usb hub?

I used the drivers that iBasso has available for download from their website.  There were no issues installing them and getting them to work with the D7.

 

I was not using a USB hub when I installed the D7 but I did install one yesterday to clear up the backgroun noise level (which worked).

Absolute Quality?

 

If you (all) describe the SQ of the iBasso D7 in this thread, you refer to it as being "excellent for the price" or something similar.

 

In absolute terms, how would you rate this box? Something like "as good as some middle of the road DAC for xxx$", "maybe as good as an average integrated CDP for xxx$", 

 

I am looking for a DAC fed via USB by my Netbook running OSX (OS doesn't matter, but not having to use windows is a plus). I  prefer listening to JBL TI 3000 via Mission Cyrus III amp, but I  have Sennheiser HD 555 for the guitar amp :).

I want to exchange the speakers and implement room correction (like http://www.acourate.com/ ), and the DAC should reflect the quality of the chain, thus it should be "decent" - whatever that means... Posting here as here are most of googles hits for iBasso D7. I am intersted because it is one of the few DAC wit asynchronous USB.

 

Thanks for any comments!

If you don't need the headphone amp in the D7, check out the HRT MusicStreamer lineup :-)

Yes, they were my initial choice, but I read mixed comments on the music streamer, while I didn't find plain negative comments on the d7.

 

However, comments like "needs time to burn in", "for the price", "if you need portability" in this thread are not entirely positive too.

 

How would you compare them?

 

Thanks

This is amazing! I received the D7 today - I ordered Monday (I'm in AZ)! I am listening to it with my Q701 as I write this, excellent SQ. No problems installing on imac by the way (though I did get that usb message). Definite upgrade from D6 dac, more than I expected. Impressed so far by the D7. Later...

post #399 of 671

OK, got it running on XP tonight! But only with my self-written audio player with ASIO at 44.1kHz. At higher frequencies I got an error.

With Foobar I had no luck. I got an error that Foobar can't set the frequency at the ASIO device.

 

@jfrocke: what audio player do you use?

post #400 of 671


I think that the D7 is driving my modded Fostex T50rp just as fine as my much more powerfull Ming Da MC84 tube amp at the listening level, that I'm using, which might be somewhat low, as I find that other people have a tendency to up the volume, when they try my cans. If you look at the measurements at http://www.innerfidelity.com/headphone-data-sheet-downloads you will that the LCD-2 and the modded fostex are close in their demands of power and the load they represent to the amplifier, so I guess that the D7 will do fine, with the LCD-2 at least the HE-500 is more demanding.

I primarily use XMPLAY, which works fine with the D7.  I have also used JRiver with it.

Can you play 24/96-FLAC-files, too? In ASIO-mode?

post #403 of 671

I'm in a similar boat - I'm in the market for a DAC and am interested in something that is "reasonably priced" and which can do 24/192 over USB. I do my listening through a MacBook Pro + BitPerfect + Gilmore Lite + Grado 325is. I'd been considering the Bifrost but at less than half the price for 24/192 over Async USB, the D7 has my attention. Like auflauf, I'm interested to know where D7 owners rank it with similarly capable (namely 24/192 over Async USB) DACs.

Can someone do a check to make see if 88.2 and 176.4kHz sample rates work/play back properly? Here are a few links to free downloads:

 

88.2kHz: http://www.eclassical.com/pages/24-bit-faq.html

176.4kHz: http://www.computeraudiophile.com/content/Complimentary-241764-HRx-Downloads-Courtesy-Reference-Recordings

192kHz (see "24bit 192kHz Free Lossless Audio Codec"): http://www.linnrecords.com/linn-downloads-testfiles.aspx

 

I have a few files at 88.2 and 176.4kHz sampling rates, and would like to ensure they play back properly over USB. Some products I've considered (the DacMagic lines) do not support certain frequencies over USB, only over SPDIF. Any other issues with 96kHz files or other rates from anyone...? Seems that the supported rates can vary depending on the USB chip implemented as well!

 

Thanks for your help!

I already tried. 44.1, 48, 88.2, 96, 192 are supported perfectly, while it doesn't support 176.4. I have to downsample 176.4 to 88.2. That's the only sample rate that it doesn't support, for some odd reason. This is in Foobar w/WASAPI.
