It does, however the extent to which it does will vary depending on how noisy the computer's USB bus is.

According to Larry Ho, the more USB devices you have connected the dirtier the bus is, both V+ and GND.

This is especially true of moving parts devices such as spinning HDDs, they should always be situated on a separate bus if possible.

I have had similar success using either the iFi iUSBPower, or Vaunix Lab Brick, a "blacker" more quiet background on which stereo image size and focus, and detail retrieval including micro dynamic contrast are enhanced. YMMV:

GO 1000 plugged directly into iFi iUSBPower.



Notice any difference? The Vaunix has a model about $250, the other is much more, $500+....

Both units pictured are $199, and there seems to be little difference between the two sonically in my system.

The Vaunix is a hub and can power/filter up to 4 devices. The iUSBPower has a ground isolation switch, while the Vaunix by default severs the ground from the computer, but it isn't switchable.

The Vaunix design also exceeds the USB 2.0 power spec, it will output more than 500mA per port, up to a total of 24 watts, useful if powering more than one device.

So they are different in terms of the potential application but similar in sound quality in my system, and not a subtle hard to listen for type of thing.

That's a Shakti On-Line.

Does it actually it actually make an audible difference?

Sounds good, just ordered the Vaunix...the GO 1k sounds great as it is, anything extra would be amazing, but willing to give it a go. Also curious about the Shakti, what's up with that?

The Shakti On-lines retail for $99 and on sale for $85 at www.highend-electronics.com which indicates they are for cables or internal circuit parts.

Not as pictured, however placing it directly on top of the DAC did have a small/subtle effect in opening up the stereo soundstage a little bit. This isn't a big deal with headphones, more audible through loudspeakers that are arranged away from wall boundaries for best stereo imaging.

The On-Lines are really best used on unshielded analog interconnect cables that are out of necessity in close proximity to power cords or power supplies.

The star of the Shakti product lineup for 20 years is their Shakti Stone, really an incredible value for use on any component's power supply and has to be heard to be believed. Not subtle, or system dependent, an easily repeatable result on every system/component I've ever used it on. Demonstrated to 2 different non-audiophile aquaintences, they both bought one.

The only drawback with using the Vaunix and GO1000 together is the orientation of the USB ports. One or the other will need to be upside down.

This isn't the case only with the Vaunix, various different computers or hubs don't seem to follow a set standard for port orientation. The GO1000's Slacker cable will correct for that and allow both devices to be used right side up. However I don't like the sound of the Slacker as compared to the AQ DragonTail, but unfortunately the DT does not correct the orientation.

So my set-up has the Vaunix hub on the computer side (arguably where it belongs as I can plug various other devices such as a digital camera or thumb drive into it), and I use the iFi iUSBPower on the other end of the chain nearest the DAC, it's port orientation does not turn the GO1000 upside down.

Interesting, maybe I'll get The Stone if I ever have a few hundred dollars laying around.

Topic please guys.

I know the Geek 1000 is more than capable of driving the LCD-2.  Has anyone tried the Geek 450 with LCD-2?

That said, I recognize DSD is more curiosity.  98% of my music is CD quality.  A bit more DVD quality.  DSD is less than 0.5%. :-)

 

So, now DSD works!! :L3000:

 

For the record, if someone is having the same troubles...  I decided to reinstall my computer.  I ran out of hard disk space and felt the whole thing was much slower than it should.  So, instead of cloning the old HD into the new one, I started form scratch.  Yes, it is a lot of work to install all drivers and deal with Window license activation.  But now my system is noticiably faster and DSD works!

 

Impressions of DSD:  I am having tons of fun with it!  I am even encoding PCM to DSD.  In my main system, this means great dynamics and a live-like song, although bass gets a bit blomy and overall presentation is grainier.  But I think the trade-off is worth it.  

 

Some songs work extremely well... others less so.  In particular, Cassandra Wilson's Strange Fruit is just mesmerizing transcoded into DSD.  Try it if you have it... :-)

 

As I said, tons of fun!! :-)

It will be interesting to see how the Geek Out handles DSD. At the moment, I tried some test tracks provided for free, legally, from Ayre and I don't like the DSD recordings compared to the PCM ones since they sounded harsher to my ears. I thought it was due to Audirvana processing the DSD format to PCM since I don't have a native DSD-capable DAC, but one of my friends has a Sony ZX1 portable media player that can playback DSD files and he came to the same conclusion as me.
