what's the bass impact like on the O2 with an srm-717?

Not something I'd worry about. :)

I see from one of your previous posts that you've tried the DT880? If you find that the DT880 has enough bass, then don't sweat it, you'd probably find the O2 bass from the 717 more than enuf too. I've tried the DT880 in the past, found the bass to be sufficient. Owned the O2mk1 and 717 in the past, bass was DEFINITELY NOT an issue.

O2 is "1 million" times better.

    Arrived yesterday and it really opens up every electrostatic headphone that I own. I was looking for an amp that can bring more bass out of my HE90 than HEV90 so I drained my pocket to bid on this and

  • I have been getting back at this..working up to a limited run of these as the STAX SR-X9000 and Audeze CRBN have made that need to happen. But the chassis is extraordinarily expensive and difficult to

  • Isn't everybody glad that I'm crazy enough to buy this stuff and have Kevin rip it apart?

Most of the bass-heads I know was pretty impressed with the kind of bass that the O2 was outputting. Changed the general impressions of electrostats for those who hadn't had the chance to listen to one before.

Got a Sigma Pro recently and liked its mid range but the bass seems a bit "muddy"? Not particularly punchy. Is that how it is or is mine the odd one out?

I was never that impressed with the Sigma Pro, it always sounded a bit out of control and the bass suffered. The SR-Sigma and Sigma 404 can rock with the best of them though...

Thanks Birgir for re-affirming my queries, thought I had gotten a "faulty" pair, nonetheless, I'm disappointed with the sound. Time to look for a cheap 404 or Lambda Sig to mutilate.

Uhm, it wouldnt be very useful to mutilate a Lambda Sig for drivers, as the Sigma Pro already has Lambda Sig drivers. You would want normal bias SR-Lambda drivers, though it seems like such a shame to take a SR-Lambda apart.

I much prefer the way of taking a crappy SR-404 with a SR-Sigma and turn them into two awesome headphones. :)

Never heard the Sigma Pro, but Birgir's opinion of the other two is correct. IMHO, the Sigma/404 is the best as it has the best treble response, and a slightly smoother and deeper bottom end. I think Naotake Hayashi was a very smart man to have invented these phones. He really had a good lateral view, and came up with a different way of creating the illusion of listening to speakers in a room. He apparently liked the Sigma best, but at that time, there was nothing else in that line apart from the Sigma Pro. Now we have the Sigma/404 option.

Oh, didn't know that Sigma Pros utilized Lambda Sig drivers. Thanks for the heads up before I do something doofus.

The Sigma and Sigma Pro have the same enclosure structure don't they? So all I need do is get my hands on a pair of really cheap 404 to mutilate?

Apart from colour differences and quality of cable differences, yes - the same.

I even posted a how-to guide of sorts here on how to convert the Sigma's... :)

In this thread? Hmm... need to spend some time reading then. Thanks, really useful stuff.

Should be but I couldn't find it... :P

I have a question about the SR-80s. Can you plug and run them off a 'Pro" bias amp? I'm looking for some "test" stats.

Yes, as they are electrets, the bias doesnt matter at all.

They will work off any Stax jack since they don't need a bias supply.

Thanx Guys!

I'll see if I can't find the pics and upload them again.

That'll be wonderful. Thanks.

I'd use the SR-003 for that.

The SR-003 will tell you a lot if something goes wrong. Wrong bias voltages scream at you and it's great for picking up hum.

Hmmm, didn't think or consider that. I was just going to pick up some 303's for testing, but that seems a lot of $$$ to tie up just to test. So them thought about some lower end older STAX. I want something to test listen with before plugging in O2s. I'll look over the 003s, thanx!

What the fuck? Do I need one? If so, do I have to buy the 404's, which I already own and am not that crazy about? I have much better units.

Help!
