My impressions of HE-6 vs HD800 vs Stax SR-007 - Page 7

Yeah right ,I said we build the Adapter that can let the home amp ,powers Stax and "Normal headphones" .

I let the Picture speak for it.

 Outputs are 4 pin XLR,normal Headphones plug and Stax output(Pro biass) 

next one

This Stax energizer (normal headphones too) with CDP Arye or esoteric + home tube amp Cary SLI80

The maker of this thing only tailor make the Home amps for the old customer.

He's now running a small   transformer factory,which export the transformer all over the world.

My friend is his old customer and he is a head-fier too.We've been told or read many times that Stax are generally better than Dynamics headphones.

And in his Opinion if we can build an adapter which can turn the Homeamps to the headphones amp like Woo Wee,but with better quality parts and can drive the Dynamic headphones too,then It would be great,because it will bring more people into the Head-fi circles,because they don't need to buy a expensive headphone amp,just use this adapter .Another point is that ,we always believe that the Home amp is better than the headphones amp,because there are a lot of great home amps out there,Mark levinson,Jeff roland etc.Why we have to spend crazy sum to chase the headphones amps,if we already have a good home amp.

That's the whole story

The Back of this "Adapter"

Connect the Home amp with this "Adapter" per speaker binding Post

I will ask my friend to make more pictures of it

to make it clear,how to use this unit.

I don't know how that guy build this "Adapter",maybe he just only put two seperate circuits into this box, one for the Stax and the other for dynamic headphones, I don't know exactly

but one thing I can ensure you guys I use this thing with my 70 watt 8 ohm home amp to drive LCD2 and HD800,there's no problem,driving them.HD800 are still not defect :P

OK... so... your using the term "Stax energizer" to refer to the "Minute Adapter" - correct?

And... the "Minute Adapter" is similar to a WEE... except... it also drives dynamic headphones... and... has an extra circuit and better parts?

Yes That's right. It's like you said Gradofan2. It's like the WEE except it can drive the Dynamic headphones too and it's built with  better parts (please don't ask me,which parts are better than the WEE ,my friend, the head of this project told me,It must sound better than the WEE and cheaper,if not no one here in Thailand will buy them,because they can order the WEE cheaply and like you know Woo has a really good name for making headphones amp,why do they have to risk their money for the NoName brand   ).

Just for fun Actually we here call this unit Minute "Boy BEE".

The name is just derived from our mentor :P. His name is Boy.He is a crazy Head-fier ,who loves to modify his amps and so crazy in Stax's sound.

This month, we're going to have the first big Meeting sort of Can Jamhere in Bangkok ,it's called "Thai Can Join".This Unit  "Minute Boy BEE" will be shown at the meeting,I will report my impression how the

Arye CX7emp+Krell homeamp+Minute"Boy BEE"+O2MKI or MKII stacks up against Weiss202+SR727+O2MKII ,sadly we don't have blue Hawaii here ,two of our members still wait for theirs.

 And I think we will have a chance to hear the HE90 too (There are 2 HE90 set ups here I think .One from the Senn distributor paired with HEV90,another one is from  head-fi user "Kiatijai".) It will be fun.

I have the HE-6, and Stax 4070, AKG K-1000, Senn 580 and other phones to compare to (and owned Senn 800s for a while, and have heard O2s a few times, as well as the venerable Senn Orpheus) and I don't notice this at all on the HE-6. I'm using a Schiit Lyr right now with them, but I also didn't notice it through my Benchmark DAC1 (unjumped to 0dB gain), nor with the Headroom Micro Stack combo.

I don't think the HE-6 soundstage is all that wide, but instrument separation is great and placement is fine for me. Then again, after K1000s, other headphones never really seem to have a wide soundstage.

I've got the chance to hear the HE6 again in a small gathering last weekend and still, no matter how hard I power them, I still experience slight soundstage anomalies. Initially I describe it as a "missing center image" but after hearing it again, I think I know how to describe it better: the center position is ever so slightly recessed against the left and right images. More evident with vocals but not so much with instrumental. I've drawn a crude diagram to show this issue which hopefully, makes it look clearer although the dip is perhaps not as extreme as pictured there. Do you, or anyone, hear something similar to this? 

 

Wait so this adapter can't be bought from out of Thailand?

I had the Omegas with the 007t amp for several years and finally sold them, mainly for comfort reasons, but also, they just sounded a little "weak", and now I like the definition

of my HD800s much more (and I got the Omegas because I was looking for deep, detailed definition and realness in tonality).

Was I missing a lot because I just used the 007t amp?

Thanks.

n3rdling told me that amplifiers generally do not make much of a difference to him at least for dynamic headphones because dynamics are generally easy to power. However, he told me that the difference he heard on the Omega 2 from the Stax 717 compared to the Blue Hawaii was the biggest difference he ever heard in a headphone. Omega 2s really demand a lot of power.

He plans to release it internationally too.I told him to send to someone to review this Unit,I think it won't be a long time. 

One thing I'm sorry to give a wrong price,The basic unit (1 stax out and 1 XLR or 6.3" headphones out) costs a little below 500$,but I don't know how is his price policy,The price maybe more or maybe less.

About the Amp to drive the O2.I agreed with 3nrdling (Milos) completely ,the O2 need powerful amp.

I heard the O2 with 006ta ,they sound not quite alright, like I said before.Today I heard the O2 with Srm 007TII ,I've found I just like the 507+Srm007TII more than O2+Srm007T II.The O2 still sound good,but I've found the sound is somewhat "weak" in this set up,a hiend Stax amp or  a good powerful home amps + "Wee" or "Minute Boy" should give a better result.

.

There was a lot of talk about O2 system prices.

I just wanted to add, that I purchased my:

O2 mk1 = 1800$us

GES = 1300$

So in total 3100$US.

On the other hand, a used HD800 and WA6 will set you back about 1600$us.

So about half the price.

But, for me at least, it was half the system.

And others have reported the GES isn't really adequate to drive the O2's to their optimum, might as well use a 007t II, or 727 - need the WES, or better yet the KGSS, or BHSE. 

So the multiple is much higher than that.
