Looking for Susvara 3.5mm in mint condition, with packaging, cables, everything that came with them included.

Hi, looking to buy a Singxer SA-1. Would like to negotiate the price. Thanks

  I don't feed it anything special, besides the fact that it naturally responds to my headphone's Peace APO EQ lol. But I was reading that some people needed virtual RCA connections from software, because their 3.5mm connection on their soundcard was being used by their headphones.   I simply...

That's because they're targeting audiophiles. At that point, suggested "requirements" don't mean anything. Loads of setups with people barely stressing their super powered amps, but they'll insist on it based on nothing.   In any case, I've never seen any headphone manufacturer's suggested...

Headphone prices are getting even more dumb. 

  Wasn't aware of this. So the NFB-1 has dual differential input, good to know. Is that what they refer to as "two pair single-ended class A FET buffers in the input" ?

There is no point in a balanced amp if it's not for a fully balanced system (meaning + balanced dac and reterminated headphone cable). 

  I agree, they sound awesome with them. Plus more comfortable than the other pads I tried (stock and 55X). Those were too thin for me, ears were touching the drivers.

  You think it's a joke but reality can be comical. The K7XX is for one particular marketplace, sounds the same as the K702 anniv, and K712 -- if you change pads. Cheaper MSRP than the K712 though. To my knowledge, the only difference between them is the pads (that's where I assume the...

  Neutral in headphones (that are all sold for general public) doesn't exist because of HRTF (an individual's measurements), which isn't a concern for speakers. If the response really was neutral to your ears the music is the only thing that could possibly be "boring", as the cans are just be a...

BMKII internals:   Chips (top one is the new firmware, SFW2):   SFW2 firmware installed:     Impressions (take with grain of salt because this isn't a direct A/B comparison considering the time it takes to install the chip is longer than echoic memory):   Sounds a bit better to...

I just got my upgrade chip, will post what I think of it later and post screens of the insides of the BMKII.

  Do what?    Edit: nevermind lol tired, didn't read that right

  We're not talking about 45 year old crap though. The actual amp has great design. I was iffy about the whole chinese ebay thing but it's a great product especially considering the price, enough to be a big hit on massdrop. What's happening is that a couple people are unhappy with the sound...

  Too costly, and it would make too much sense at the same time lol.

  Yes thank you, I don't know why EQ is so hated on H-F. I mean I know it has to do with purity or it being a digital process (whatever that means at this point, in an industry ruled by the digital process anyway), but it makes no sense to me to roll tubes, opamps, buy multiple dacs and amps...

You guys hear about this "op-amp rolling" craze? I had no idea what it was until the Gustard H10 thread became a thread about op-amp rolling recently.   Here's an example of op-amp comparisons *please note this is not to humiliate in any way, just need to hear at least someone else speaking...

  Thanks for this.  For some reason I thought manufacturer specs for efficiency were accurate. I go to Tyll's measurements for the FR graphs mainly, only. Can't trust the data from people who sell you stuff, sad world. 20 frkin milliwatts to get 90dB and somehow they get 1mW for 83.5dB on their...

With there being no manual/instructions with this thing, I can imagine not everyone knows how this thing works, even for aspects that may appear obvious. A good amount of pages back, I remember telling someone why their H10 sounded bad when their switch was in the incorrect position when they...

  I answered the question, I thought that's what he wanted to know. That's all it is. You felt the need to speak for him for some reason, what was the point of that? Just curious.   Either way man, chill maybe someone will answer the question in the way you want, I obviously won't stop it...

  I don't know what Balanced/XLR = balanced switch, unbalanced/SE/RCA=unbalanced switch doesn't tell you. It's the mechanic explained for anyone. You don't even need to read the labeling either, you know it's messed up just hearing the wrong setting.   If you're after deeper technicalities of...

If your H10 is connected balanced (XLR from a balanced dac), you flip the the switch to balanced, if it isn't (RCA) you switch it to unbalanced.

Proper Class-A operation, design or implementation means the gain doesn't affect the FR in any case. It sounds more like typical Equal Loudness Contours being affected.

Differences in frequency response when changing gain can easily be attributed to Equal Loudness Contours. A change in gain affects it considerably. Louder is heard as better for most people. These audible differences are always about perception than what the electronic device is actually...

  Is he a professional? He seems to want to sell these to people but the analogy doesn't work if he wants to be concise (unless the HE-1000 has head tracking technology unknown to even the makers). Also funny is that the Oculus Rift, for what it does, will be about a tenth of the HE-1000's...
