Another question I have is about the amplifier. Can I use this http://www.kingrex.co.uk/leadacid_battery.html instead of the wall wart with the SRM-252S?

 

You can, but you should use an intelligent Lithium battery pack.

For example:

The battery should should cut off power before it gets too low, to protect the battery from over-discharging, protect the battery from getting too low..

Is there any difference beetween SR-202 and SR-207 ? :confused:

Please do NOT answer "five units" :ph34r:

I've tried the stock SR-207 vs the SR-202 with leather pads on the SRM-252S and I found the SR-202 to sound smoother and the bass had more extension. I'm not sure if it was the leather pads making a difference though since the SR-207's stock plastic leather doesn't quite get a good seal on my head.

Oh man, I'm going to have to get me some of those leather pads!

A little bump with a question. At some points we discussed amps, slew rate and connecting more than 1 earspeaker to the Stax amplifiers.

 

  1. Why should it be a problem driving, say, 3 earspeakers at once (I don't quite get it, the current should be pretty darn low anyway, even at 20 kHz)?
  2. I remember slew rates being thrown around - something like 60-70 V/ms. That's pretty low, I mean that'd make the amp unable to produce more than 3-3.5V p-p 20k hz tones, which makes no sense?

 

I hope someone has the answers.. Thanks :) 

 

EDIT: I figured we were talking microseconds. So that'd be more like 3000-3500 V p-p for a 20k Hz tone. Still, if anyone can shed some light on question 1 and perhaps elaborate to 2?

Yes, we are talking about microseconds.

You are correct, 60-70 Volts per microsecond is quite a bit for a bandwidth of 20 kHz.

 

Not too sure if the Stax amps are designed to drive 3 earspeakers.  Anybody?

A few of us had a mini stax meet a couple weekends ago and ran three pro bias stax (202, 207, 404) through an srm-006t and it drove them all pretty decently at the same time.


Also, in case anyone else was looking for a case for their STAX Lambdas, the Pelican 1200 case fits, but it's quite a tight fit:

So I feel like I've reached my summit point for headphones (my v-moda's leaned towards as bass heavy, akg's as extremely wide open backs, fostex t50rp's as planar magnetics). I was hoping to jump on the Stax entry level train... but it seems I have missed it.

 

Would I be better off just to finish off modding my Fostex T50rp's, or expect something better out of the Stax SR-Lambda Normal Bias? If I can even find it. I chose those models because my wallet was happy to hear that it can be sold around for under $250.

Some thinks some of the Stax earspeakers (mostly the newer ones) are comparable to a k701 on steroids. I'd say a Stax system could be a definite upgrade. The only problem is that the prices are inflated compared to what they used to be. I buy my Stax gear used, and only if the price is really good.

Looks like my wallet is going to be safe for a while now, thanks davidsh :D

Just keep a lookout on the market, getting into pricing and stuff is a little hard, but eventually you might get lucky and find something good for cheap. Just stay away from anything with imbalance and that kind of stuff, and go for electrostats for now (not electrets).
