Hi Scooter![quote user="scooter"]
I have tried the SR-009, SR-007, SR-507, and SR-407 many times over a total of some 5 hours with a variety of sources but always with some Stax branded amplifier. Every time I thought / suspected that the big Stax...

Scooter, being myself a Stax listener, have you tried portable Staxes? Model 001 or something like that.I've never heard them, but I'm wondering what they are worthas an interesting attempt of portable electrostats.Cheers,N-set...

Hi N-set,
Interesting query on the small Stax. I don't want to go down the path of equipment reviewer but do want to answer your question and contribute where I can.
I have not tried the portable Stax model. Out of the gate, I could not reconc...

[quote user="Paul S"]N-set, are you pretty sure that the "direct drive" tube amp need not be PP? Does the Stax amp have +/- typical RC output? Would it perhaps make more sense to "update" the Stax amp?ATH-50 cans would sure make your life easier......

This is something I've been chewing on for quite some time and finally decidedto make it happen: a serious Stax headphone amplifier.I hope I can use this space as a sort of a blog-report on the progress...if not feel free to remove. I've been "forced...

[quote user="Romy the Cat"]It is unquestionably an ambiguous project. The topmost question that I would ask myself after this project would be the following: can Milq-biased 6E5P to be as good (sound-wise) DC driver as some vintage direct heated tube...

Paul, would you think 6336 will be more stable/predictable?Have you had any experience with it?30H: sorry, forgot to mention that the PP pair is autobiasedwith a common 900R resistor...EL34: indeed it's a very popular tube for driving Stax electrosta...

[quote user="N-set"] I've been "forced" to listen on headphones due to real estate constraints and it seems those constraints will stay for few more years.
At the moment I'm using Stax Omega 2 MkI powered by a solid state amp Stax 717. I've always...

[quote user="scooter"] However, I had one very interesting observation living the "Class D;" plugged directly into the wall socket, they always sounded the same, regardless of day or time of day. That is the only audio gear I have ever encountered th...

Thanks for all the suggestions. As it happens, there were no exhibitors at the Flemings Hotel this year. But I did pop into the Stax stall before listening to anything else.In general, I was pretty disappointed with what I heard. Most of the ‘convent...

No doubt you have reverse-engineered the amp's output plots from the Stax' input requirements/limitations; right?The Chimera Axiom is a tank circuit, with a zillion taps off a giant, complex tranny. Looks like your sections are ?stepped in terms of ...

Paul, I've managed to glue the image:`Diodes or resistors is absolutely secondary to me, I wanted to trythe main idea. You seem to have good experiences with EL34, right?Cheers,jk...

Decoud (and others), where do you source big Nichicon caps, pref. in EU?I'm slowly preparing to attack a Staxquiades - a mastodont Milq inspiredamp to power Stax headphones (PP 6E5 DC to PP 2A3/300B/EL34). I need 10.000uF/500V and 10.000/350V caps.Mo...

Scooter, thank you for the warnings. I already own O2 MkI for +/-2 yrs and got to know them a bit. As I said I do not like headphones in generalbut I have no other choice. I own 2 more staxes: Sigma and Lambda Pro and Omega can do things others canno...

Dear Roman and all... also unrequested/unsolicited, MUST give my opinion on the above... I had to translate my 2,3 meters from my Gotorama speakers system, and obtained 7,6 or so feet... it's angled 110° in front of my head, placed on 5,3 meters long...

Gentlemen, I can only hope to be wrong on the air-borne feedback.Actually your project Anthony made me think of coming back to my Staxquiades project - a Milq inspired monster amp for my Stax headphones. Do you have a source of big PSU Nichicons at ...

I heard the same not just from one but from a few guys for my playback as well! I think it is because of the all encompassing effect and the strength of the stereo image. Most people have never heard that strong of a phantom centre, or an orchestra a...

Just a short comment on the motor rumble on my particular example of EMT930: using a 40yrs old idler I could clearly hear the joyful sound of the motor when playing a test empty track (through quite efficient Stax O2 headphones, max volume on their 7...

This is probably a related question to LED bulbs with their electronic transformer crap inside.I have not noticed any noise with the full volume up on my Stax O2 so far andI was intentionally looking for it. There is only a gentle crack when I switch...

"How do you audition the equipment that you build? Do you do listening tests at all?
No, basically I don’t do that. I have some Strax headphones for some listening, but I don’t judge the electronics based on listening tests.Does anyone else in...
