This is exactly what happened to mine, through several emails with Kingwa the only option was to send it in for warranty repair.

No kidding, compared to what they usually retail at $80 is a great deal… however I wouldn’t say they are worth much more than $80. I like mine but to be honest your paying for the fit and finish more than anything (they are pretty and comfortable as all hell). Not too make life difficult, but...

Yeah... I was expecting as much. Kingwa has replied, so I hope this is a smooth process. Have you, or anyone for that matter had any experience in doing this?

So, unfortunately only after 2 months of use my Nfb-15 is failing. Last night while listening to music on a low volume the right channel all of a sudden began to pop, crackle and distort. The unit was free of any surrounding obstructions to impede its ability to ventilate, and was not driving...

Many people love the 598, and I do enjoy mine…. However…. I never listen to mine without a bell EQ right around 4000hz because I find them to be fatiguing, even painful at higher volumes. Working within the ohm load you have to consider makes it tough, but if he is coming from the “beats” back...

I felt similar about the idea but worth asking, mostly it was to relieve the DAC from whatever current was drawn to run the preamp at higher volumes. I too enjoy the nfb-15, its been a GREAT little unit for the price.

I have a question for you gentleman, I just received my nfb-15 which I'm using as my HPA, DAC, and pre-amp to power an emotiva xpa-200 to some psb image b6's. Now that the nfb-3amp is available I'm considering getting that to use as my HPA and pre-amp and allow the nfb-15 dac to use its own psu...

What 598 cable upgrade did you get? I own a pair myself and wouldn't mind trying this. thanks!

I own the 598's, and though they are great the last thing i would call them is "warm". depending on the DAC and amp it changes a lot, my ears like them with a wolfson dac and a beefy amp does help the bottom ends authority but if you drive them hard they can break up.  If the Fulla does what Ive...

hey, its pretty cool to stumble on this thread as not only am I looking at purchasing the nfb-29, but airmotiv 6s's aswell. reading through it seems like I couldn't go wrong but could you give a little more detail on how well this unit works as a preamp and if at all possible your opinion of the...

Ah my mistake. well I completely agree with you, my passions are music (as a musician) and HIFI gear, headfi is a new avenue for me. that being said Ive been tinkering with tube amps for a while so the idea of doing so in headfi at a relatively low cost makes my day. have you yourself had any...

the tweaker inside me goes right to the the Little Dot, but on a practical note the adjustable gain stages and ease of replacing tubes if you had to makes it a winner all round for me, considering my main cans are 50 ohm hd589's.  Could the Vali design and construction be that much better that...

Both are tube hybrid, both have had great reviews and both sit at a similar price point...   But what would you choose?   Why?

Hey everyone,   Recently purchased some HD598's and I'm looking for some amp opinions/options/experiences. I really like the no frills approach and cost of the Schiit audio gear, in particular the modi magni combo or substituting in the vali amp (This would be my preference). My question for...

Well both the videos and the extensive talk on this thread has made me very informed, and very torn ahaha. I posted a thread looking for advise on my next purchase (replacing shure srh440) for open cans. my choices included the senn hd598 and ad900x. But now due to the wide range of music I...

I’ve narrowed my choices to three sets, the Sennheiser hd 598, AKG q701, ATH AD900. Does anyone have experience with these? I’m buying online and don’t really have an option to demo before buying.

I’ve been the owner of a pair of Shure SRH440’s that I’ve replaces the ear surrounds with the SRH840’s. even after a long break in period as well as the upgraded foam I find these not only uncomfortable after 45min of listening but also fatiguing to listen to after just as long. I’ve tried...
