post #556 of 666

It will be interesting to see a review comparing these to a pair of Stax Alpha-Pro, (both have flimsy construction, mid-size drivers, high-ish bias voltage).

post #557 of 666

I've compared them before I killed yet another SR-Alpha Pro Excellent in the name of sourcing parts...  :o  The Stax are brighter and with a bit more bite to them but over all they are far more coherent and controlled.  I also wouldn't call the Alpha/Gamma construction flimsy, the housing is a bit weak but the drivers are very well made.  The arc is also strong enough to last decades to come.  The Kingsound KS-H1 drivers by comparison are worse than the DIY stuff we are making. 

 

While I'm at it, here are the first impressions by a friend of mine who borrowed my heavily modified set:

The Omega 2s are so much better than these Chinese headphones! The bass in one track on the Chinese ones sounded like I was listening to the track inside a aluminum shack with nothing but a 10000w subwoofer in it. It was so boomy and muddy. Sounded like utter crap. On the same track, the Omega 2 is authoritative, but clear and crisp. In more midrange based tracks, it has better soundstaging, separation and more pleasant characteristics overall. Not to mention those Chinese ones are as unpleasant as **** to wear.

Don't get me wrong, they sound very good compared to earbuds or regular ****ty headphones (except for maybe the bass…I don't know what's up with that…), but man alive, the Stax eviscerate them.

 

Amplifiaction used was either a KGSS or one of my Blue Hawaii's as he has both.

Well that's good to know.

KS crushed again. By an O2 on a KGSS or a BH?

I'll be spending my lunch money on an O2. Yesiree Bob!

post #559 of 666

The O2's are a lot more expensive (3x?) then the KS, so the comparison result above is not surprising.

I found the KS phones very comfy to wear. of course the pads don't give me that warm and fuzzy feeling like the O2 does, but I suspect KS pads don't cost $150 either. :wink_face:

 

The drivers are protected in the housing, as long as the housing holds the drivers should be safe. The all-plastic drivers in ESP950 is not that sturdy either so maybe the KS drives are adequate for normal use.  If they are at ~$400 I would probably buy a set just to see how well they hold up in the long term (use a real 450V bias and run them 24/7). Spritzer, did the buzzing start before or after you open the ear cups?

 

 

Maybe somebody (MoonAudio?) should start a demo/loaner program so more people can try & review them?

It's not always true that just because something is more expensive it is automatically better. :wink_face:

Just like the theory behind the O2? :D

If you read the beginning of the thread then these were supposed to compete with the SR-009...  :rolleyes:  In stock configuration and with the M-10/M-20 amps they are pretty horrible.  Stax SRS-2170 is better is every way except maybe comfort.  I'm not much of a fan of the new Lambda earpads... 

 

The KS earpads are in the trash now as they simply don't work.  Now my set has the HM5 Brainwaivz (or something like that) pads which are 17$ for the pair shipped anywhere in the world.  Better quality than the stock pads by a mile and much smaller too. 

 

The buzzing was there from the start and the ditto on the rattle in the left driver at some bass frequencies. 

 

As for the bias, that 450V figure is just BS.  The "manual" for these clearly states they should be used at Pro bias level and both the amps have a bias voltage of ca. 580V.

you mean the "poor man's Omega" thing? well the "poor man" part is the key.:wink_face:

 

Thanks for the Alpha-pro/KS comparison by the way.

 

I will ask MoonAudio about the official bias voltage for the KS and see if they are willing to start a loaner program to promote the KS.

Agreed, but if the product has been on the market for a while and survived ok, its price usually reflects the performance at least to some degree, no?

post #567 of 666

To that extent I agree. People here usually boast about something new and expensive being the best (see SG's reviews as an example), people jump all over the hype wagon, wait for things to settle down, bias withdrawn and you see people quickly start moving on again or sell the new product (LCD2's as an example). Not always the case but a very common conception with what's been happening on the market in the past 4 years.

The exception must be the Ultrasone ED10...!!!!!

post #569 of 666

MoonAudio confirmed the KS is safe to use with Stax amp, though the official bias voltage in the spec sheet is still 450V.

On the other hand, "I doubt there will be a loaner Pair. I will send to HeadFi meets if requested.".... so, no loaner program at least for now.

new headphones coming out for this system - the H-02.
