How well does the D7 drive a pair of HD-600s?

It drives my HD650's with no problem and provides plenty of bass control. They sound great with it.

Can u do a brief comparison between this and D6? Does D6 win by a large-margin?

To slip in my opinion, I think that the choice between the D6 and D7 will depend on personal listening preferences, whether you want to roll opamps, and whether you need portability away from your computer. Both sound excellent.

hi everyone,

I'm having a small problem with my d7 and hoping someone can help. When initially trying to load the driver my computer would not recognize the D7. Eventually I was able to make it work by having the unit plugged in and on before installing the driver (thinkpad, windows 7 professional).

The only issue I have now is every time I plug it in Windows will automatically "stop" the USB port with error code 43 (seen under device manager, USB controllers).

Manually disabling and re-enabling the USB port fixes the issue - Windows recognizes the D7 and it works fine - until the next time I plug it in.

I've tried different cables, USB ports, reinstalling drivers, etc.

This really is no big deal, the D7 sounds so incredible and this is only a minor inconvenience - just wondering if anyone else has seen this or has any suggestions.

 

Thanks

As HighFlight mentions, if you want portability with a battery the D6, otherwise, the D7 gives up nothing in the sound department, it is excellent.

Anyone know how the D7 compares with the E17?

 

and what opamp is used in the D7? 

 

Thanks

That's an interesting question. I would like to know too, someone please enlighten us.

I recently purchased a D7.  Although music through the D7 is promising, I am hearing electrical noise through my sensitive Ultimate Ears Reference Monitors at low volumes; it also exists at higher volumes, but is partially masked by the music.  I have tried 2 different laptops (using battery only) and 3 different USB cables.  The noise makes a fairly new and expensive ThinkPad X220 unusable as it is clearly audible in quiet passages of the music.  It is less of a problem on an older Acer laptop. I am sure that the noise is generated by the laptops; moving the mouse on the Thinkpad increases the intensity of the noise on the Thinkpad. There is no significant difference in noise between the different USB ports.  The D7 seems not to be galvanically isolated from the computer.  Do you have any suggestions to remove/reduce the electrical noise?  Will a USB hub help?  Is anyone else having this problem with sensitive IEMs? 

 

Thanks!

My Westone ES5 is much more sensitive to the UERM. At low volume on my Macbook Pro, it is totally silent. I have a little bit of electrical noise if I connect via an USB hub but not when I connect direct to my Macbook Pro.

 

Since the electrical noise on my Belkin USB hub is low, a better USB hub might solve the problem if it is your laptops that is giving you problem.

I actually received my D7 yesterday and noticed crackle's and popping during my time listening. I changed a few settings on my Windows 7 computer and it reduced the frequency of these abnormalities. I am wondering if this might help in your situation too. A pretty decent guide for Windows 7 optimization when it comes to audio can be found in this guide.  The only change I used from this guide is under the topic "Change Processor Scheduling". This adjustment changes how Windows allocates the processor resources to be optimized for "Background Services" which I am assuming allows more processing power to be available to the handling of the USB functions. Hope this helps in your particular situation as well.

just got a reply back from Ibasso, the D7 uses OPA1611

Just sent payment for one of these Sidewinders...

 

Funny thing, I was looking for a replacement/upgrade for my uDAC-2 to power my new PK1s (I love the fit and convenience of buds), sourced through my laptop. Not but a few minutes of searching and I found this thread. Everything seems to be right on the money for my needs, from what I am reading here. I hope the driver install/setup goes relatively smoothly. I am looking forward to hearing it soon! 

 

Thanks HiFlight (as always) for taking the time to test, review and post your thoughts. I appreciate everyone's feedback and thoughts, so far - very helpful.

That seems a very nice choise, as it is the same as the original stepdance and the mono version of the OPA1612 used in the DACport.
