The Stax Thread III

[Golfnutz]

  What?

Pierre Paya went to a Hotel in Paris, to reflect. I think.

No I think he is a business seller of headphone http://www.casques-headphones.com/index

It is true, as well as it's a friend and also a very good tester of headphones (in blind or not)
 
See our meeting of 7-8 September 2013 at my home, with Karim, Frederic, Pierre and I (Eric)

Listen, listen, listen; some attention, ladies and gentlemen; Here are the results of the first Hunger games audio (comparison of amplifiers with headphones Stax SR-009). 
 
Six tributes at the start: 
District 1: WooAudio Wee Wee modified and unmodified (coupled to RKV-II amplifier) 
District 2: Stax SRM 727 and SRM 007t 
District 12: Audiovalve Verto unmodified and modified Verto (coupled to RKV-II amplifier)
 
Only one winner normally. 
 
The winner is .... or rather ... are both tributes from District 12, the AudioValve Verto box coupled to the amplifier Audiovalve RKV-II.
 
(Nb: modification of the Verto with cutting the leg of two resistors (see photo : has not yet been achieved and it soon will be, this  modification proposed by M. Becker (of AudioVlave) aims to further improve the clarity of Verto, yet does not lack, according to the comparative monitoring done by Peter (Pierre) to this link : http://www.homecinema-fr.com/forum/casques-haute-fidelite/verto-le-boitier-audiovalve-pour-casques-stax-t30052030-105.html ); this change will be carried out soon). 
 
:
 
 
.
Winner : Verto box coupled to the amplifier RKV-II (with the 009 Stax Headphone)
 
The Verto box (coupled to the amplifier RKV-II) is the winner for the best overall sound rendering over all other competitors amps, with a better overall synergy with the 009; not to mention a much better versatility of use it is also noteworthy (ie : possible listening of Stax headphones and others (no estat) like orthodynamics and electrodynamics headphones with the RKV amp).

Verto 1 vs Verto 2 (following the confrontation)
 

 
 
One Winner : District 12 : Verto 2 Box (with RKV II amp and Stax SR-009 or SR-507)

so like....i guess youre a fan of the verto box?  please tell us some more details i'm very interested.

 

[blubliss]

go away, please.

I discovered, just like you. 
 
A test translation (partial):
 
" The gap is widening a little more with the SRM727 and the Woo Audio Wee. 

Anecdote: 
Before announcing here that the best extension of Verto 2 at high frequencies do not cause hardness, I left my SR-009 and tried my SR-507. 
The 507 is  less soft than the 009. 
Then I connected the 507 and I listened. 
Time passed and it was only after a while, I do not know, maybe 20/30 minutes, I realized that I still had the 507 on the ears ... I forgot ... 
Finally I kept it still a good time and I loved the beautiful sounds of all RKVII / Verto 2 / SR-507. 
The SR-009 of course brings me further than the SR507, but frankly, this is the best cession of listening I made to date with a 507, headphone that yet I know by heart. 
I heard among many, the piece of anthology: Mediterranean Sundance, from the album "Friday Night in San Francisco" and played among others by the late Paco de Lucia. 
Both guitars have best contours with Verto 2 ; attacks strings sharper, more accurate. 
Overall I feel I have been a light veil over all when I return to the Verto 1.  
I heard these criteria better highlighted with Verto 2 of all the songs I listened to. 
Listening to classical music, ditto, more accuracy and transparency, but the violins will not fail over so far towards a more sound "slender" or 'leaner' 
They are better defined, rise above with more energy and are at the same time more purposes, just as soft, and 'fluffy '. "

I guess it was time, but the stax mafia is working hard on a circlotron for electrostatics.
I have 2 versions, one of which is all solid state, and fully dc coupled, and the
other uses a pair of 6s4's for the gain stage, and either triodes, or ultra low
capacitance silicon carbide fets for the outputs and is also fully dc coupled.
 
circlotrons make my brain hurt.  Its all Jason's fault.

Don't know much about these designs but will it look like this one?
 
 
 

 

[kevin gilmore]

not going to be that big.

The atmaspheres are AC coupled and into high impedance can probably
only do 100 vpp

mine are dc coupled and 2000 vppss

  Hello,

Eric

 
The answer is 42 eric.

 

[Ra97oR]

All that talk on a modded 727 sounding nice... decisions decisions.

 

[Ali-Pacha]

   
The answer is 42 eric.

And Abyss are still better phones than 007 and 009. Period.

Listening to the Led Zep on the 007 mk1 and the KGSShv. A simple increase of the volume pot brings out detail and resolution in all its glory ! I've been shy of turning the pot past 8 but not any more

I think having a new design of Stat amp on the scene is great news. Especially with input from the Master himself. We will be waiting in anticipation.
