I'm asking purely out of curiosity, not to start a war of words.
I own a GO1000, and a CEntrance HiFi-M8, they seem very similar in terms of a low noise/quiet background, either when listening to music or at idle.
The M8 is battery powered, the GO1000 of course is bus powered and logically should be noisier because of that, but I use an iUSBPower inline to mitigate any potential noise issues from the computer.
I'm also not suggesting all Geek Out owners "need" to run out and buy an add-on such as the iUSBPower to solve some sort of inherent noise problem. ALL of my USB DACs benefit from he iUSBPower, not just the GO1000.
It has been asked a few times, me and @miceblue have described it here and in LH Labs forum, but let me describe it again.
Mine is GO 450 that seems to have higher noise floor than your GO 1000.
The background noise mostly heard with sensitive IEM, such as my DUNU DN-1000 and DN-2000, and less heard on headphones, especially high impedance headphones. For example, I cannot hear the noise on my HD800.
The background noise especially heard when there is no music, the moment I'm plugging in the IEM. It's quite clear the changes from silent before plugging, and hearing 'hisss' noise after plugging to the headphone output of GO 450.
It is also heard during the soft passages of music.
I don't have any of that hiss problem with my other portable DACS such as Dragonfly, DACport, as well as DAPs, using the DUNUs. The hiss problem is only on my GO 450.
I hope that's clarify.
I have requested for second unit of GO 450 from the referral program, and Manny Tores has agrees to send me the second unit. I will compare the second unit of GO 450 with my current GO 450 to see if there is any problem with my current GO 450.
I've waited for more than 3 weeks for it since I reported this problem, but so far no news when it is going to be delivered. As usual, wait, wait, and wait....
I'm going to write a review of GO 450 compared with my other DACs, but waiting for the second unit of the GO 450, for a fair comparison.
