Thanks, point well taken. The Bottlehead DAC and the Yggy would definitely be more 'end game' purchases for me vs. something I felt was a necessity for good sound. This isn't for a headphone rig, it's going in to a 2 channel system. I'm not looking for a speaker upgrade any time soon as I've...

I read this whole thread and saw Mike comment a couple times that these 2009 minis sound better than newer Macs. The only reference to somewhat of a reason was that the 2009 was the lowest powered to still get the job done. I would love to hear more as to why the 2009 sounds better as a streamer...

I'm on the hunt for a semi-portable / portable amp and dac combo to pair up with my laptop (windows 10, jriver) and K712 and X2 cans. HA-2 is high on my list, what else should I look at in this price range (or a little higher)?

I'll be getting a X7 for console gaming soon to upgrade from my Mixamp thanks to this thread. On a different subject, can anybody recommend a somewhat portable or easy to manage (size wise) external device that has a headphone DSP so I can have surround from a tablet streaming Netflix? Portable...

What about the Y adapter doesn't work?

Am I going to run into any connectivity or chat sound quality issues connecting K712 + mic via a Y cable to a 2013 Mixamp's headphone jack and then Mixamp to PS4 via optical (game sound) and USB (chat + power)?  I thought by setting the PS4 'output to headpone' setting to 'chat audio' everything...

So I have the 2013 Mixamp on its way to me from Amazon, it will go with K712 and an O2 playing a PS4. Are there still chat issues connecting the Mixamp to the PS4? I was going to connect via USB but just read about sound quality issues with chat using this method?

  Thanks Mad.  Will the low efficiency of the K712 mitigate the hiss any appreciable amount?  This will be my first Mixamp so I can't say whether the hiss will be an issue.  Is the implementation of Dolby headphone the same between the 2011 and 2013?  That would be the most important to me, say...

Any opinion on which Mixamp I should go with between the 2011 and 2013 - I've read about the differences in this thread but I also came across low mic volume issues on the 2013 while reading online, not to mention the extra hiss. I also read the 2011 can't update firmware like the 2013 can. I'm...

Thought I'd try asking my question in this thread since it looks to be the most recent O2 discussion.  Could somebody please advise which gain settings I should request on the O2 if I plan to use it in combination with an Astro Mixamp for surround effect?  The Mixamp is USB powered and I've read...

  I just wanted to reformulate my question for the sake of clarity... I'd like to source match the gain options of the O2 I'm ordering with the needs of the Mixamp.  I read the Mixamp is USB powered and maxes out at 1.6v (70mW @ 32ohm).  If the sweet spot on the Mixamp's volume dial is around...

Thanks again SaLX and Evshrug. A follow up question though... How about the O2's gain settings in relation to the Mixamp - meaning the O2's standard 2.5x gain is stated to be meant for 2v desktop sources and the 6.5x gain for .5v portable sources. The Mixamp is rated at 1.6v, but is that not at...

Thanks for the reply. If you don't mind my asking, how did you arrive at the 1x suggestion - just curious. Also, I'm not aware of dip switches for the O2 - just the external in/out button selecting hi/low gain. I know you can pick the two gain levels for that switch when ordering the O2.

Can somebody please advise on proper gain settings to choose for the Objective 2 when double amping with the mixamp pro? This is to drive some Q701 or K712. I read the mixamp is 70mW at 32ohm and I also came across Astro stating it maxes out at 1.6 volts. Although I'd like to keep the mixamp at...

I'm pretty close to pulling the trigger on the Q701, are there any issues with buying AKG's or headphones in general on eBay?  I'm asking because Amazon has them for $199 but they seem to be the newer 'made in China' version and eBay still has sellers offering the 'made in Austria' version for...
