That last bit is not true. In fact he was posting questions about his Lotus on a forum which some perceived to be purchased from stolen gear money which he did not, his had it for years. From another poster from another forum. 

 

But yes he still has n3rdlings R10.

Thanks for the thoughts ... I had considered some sort of crimping scenario.

 

But truthfully, since I already have one full length extension with a very n icely installed Stax connector? Then I'll most likely just use that, in a sort of rolled up fashion, and order another extension and Stax connector and do a proper solder solution. Been wanting a nice, mostly harmless soldering introduction, anyway and this sounds perfect.

 

Higher on my priority list is getting the working Koss unit back from warranty repair and then finding myself an affordable Stax amp to use it with. ;-) ...

 

What do you all think about using a Stax SRM-252S as a driver unit for the ESP-950; would it be a significant upgrade over the E/90 Koss amp? It's attractive as it's rather affordable new and it's small, which would work well with my limited desktop space which also includes my dynamic DAC/Amp set up:

...

 

 

...

 

My other option is to find a used SRM-323 or, even better since I've owned one before and like them,  an SRM-313 ... I'm sure either of those would be better than the 252S ... at least with my  other Stax cans ... but not sure I want to wait for a used one to come up for a decent price.

Something like: http://www.cableorganizer.com/multilink-butt-splices/

If someone has no $6 soldering pencil, unlikely they have a $30 heat gun

 

I personally wouldn't use a butt splice of any kind for ANYTHING, really, except maybe for some automotive wiring, and even then I'd flow solder into it after crimping and cover it in heat-shrink.  But if someone simply will not solder, a butt splice is better than twisted wire and duct tape.  :cool:

Reality is that I spend more time with the 252A than any other amp now since it sits on my desk at work.  It's been my desk amp for a while now.  I think it's a great little amp.  I've listened to the E/90 so infrequently I don't think I can honestly compare the two, but I can say that the 252 handles the 950's just fine.  I tend to bring in a few different headphones and listen to them for a week or so.  Typically I pick a Lambda of some sort, but I often bring the 950.  If you're tight on space, it's a really good option.

I had that same thought... ha.  Hair drier?  In thinking about it, it makes sense, but when I first considered it I didn't think that that an iron would be that much cheaper than a heat gun!  From a simplicity stand point I think those butt splices with low temp solder would be easier for someone who lacked the confidence to try soldering, but certainly not an overall good option.  Definitely cheaper to solder.  And for those that are on the fence about a little DIY solder work like this, take a leap, it's pretty easy!  And fun!

One solution is just to have somebody solder the adapter for you.  It's very easy to do though even with the WPI plugs cab be a bit of a pain to work with.

It's more likely that we'd put out a hit on anybody trying to use those to populate a PCB...

Got this headphone today so I'm officially a stats owner. I bought it at $600 during the Cyber Monday sale. Honestly, at $600 for a headphone and amp, this is probably the best sound I've heard compared to any other headphone + amp at the $600 price point. I can definitely hear the speed and airiness. I love the treble, the speed here really helps as you can hear the details and decay of the treble. Soundstage is decent and imaging is great. Also, it's pretty much the least sibilant headphones I've ever heard. I found the mid-bass volume level to be fine, though it's lacking sub-bass. The bass overall does lack some definition and texture. The biggest gripe I have is that it's not as transparent as I would like it to be. It's a bit veiled to me, and this also in turn reduces the amount of details heard. I've read the amp provided really hold these back, and I'm sure the transparency problem is due to the amp.

Congrats.  Mine is coming on Monday.  You will need to get a good Stax amp to drive it properly and that should solve most of your problems.  Wonder how the ESP950 will sound out of my BHSE.

The transparency issues are probably due to the damping inside the phones.  Koss have been a bit heavy handed with it at times...

My first soldering "iron" was one of them soldering guns, woeful things for small footprint soldering. :p

congrats.

 

I expect to get mine back from Koss this next week some time (had a horrid distortion in the left channel for some reason).

 

In the mean time, not having a gazillion bucks laying about and not wanting to use the Koss energizer, I bought a new Stax SRM-252 for use with the Koss cans and a set of SR-307's I also have.

 

I initially wanted to get a SRM-323S but it's just too big to co exist with my other desktop gear. The 252 will sit/stack nicely and I can use it's parallel outputs to in turn patch my dynamic amp in to the chain.

 

Looking forward to it...

 

If you end up using just the Koss energizer, you might check out this 9V 3.00A regulated AC adapter that according to others makes a fairly significant difference in sound over the stock wall wart .. here is what I'm talking about: AC ADAPTER

 

I bought one for mine but am going to just store it with the Koss amp as I'll be using the Stax 252S for main duty.

 

Haven't had a chance to try the AC adapter as my Koss kit arrived with that distortion but when I get it back from Koss, I'm going to compare it to the wall wart.

 

Just a thought ...

Ooo thank you very much! I'm probably gonna go with the stock energizer for a while, so that is a nice tip! I think I eventually want to get a Woo WEE and connect it with my speaker amp setup. Anyone have any idea how well the ESP950 works with the WEE? Also, what's the cheapest way to get a Stax adapter?
