For those with SRM-313 or similar amps, how is the outer (smaller length) volume knob attached? The SRM-313 I recently sold did not seem to have any connection between the outer and inner volume knobs, and if tilted even slightly it would pretty much fall out. Is this normal? Is it secured some way? The volume adjustment functionality worked just fine, it's just that it had a tendency to fall out.

First impression listening to Stax... 

  Why have I been wasting all this time and money on dynamics and orthos.  Two songs in and I'm already wanting a 007 or 009.  I went with the SR-507 and SRM-323S.

Hmmm, nevermind, more research to do.

Sounds like a familiar story.

That's a great set up - live with it and enjoy. You can take your time, I have both those other ear speakers, plus a dozen others. You're in the big league, going for the summit won't get you that much further and will cost a fortune. Not discouraging you to do it eventually but spend a honeymoon with the 507.

i'm leaning toward a 717 for my sr007A...while i know it won't be as amazing as a kgsshv, i want to also upgrade my source. @spritzer has a modified exstata on his site that i'm also interested in, but waiting to hear about how it compares with the 717 powering the sr007A before making a final decision...

The 717 is a very solid amp.

I cannot tell how is it attached, but mine doesn't leave its place at all (I have a rather old SRM-313 with one normal bias and one pro bias output)..

@kugino Don't worry, the 717 works well with the 007. It's a good amp. I haven't heard an Exstata, but for me it would be very simple to choose between the two: the 717 has got a lot more recommendations than the Exstata, which has received quite some criticism over the years, although surprisingly, most people raved about it in the very beginning. Still, the 717 has always been a dead cert.

that's the impression i've been getting about the 717. and someone at the other place also made the comment that the 717 would be much easier to re-sell later on if/when i want to try something else. so i'm most likely going to pick up the 717. my other choice would have been to get the kgsshv, but i think i want to spend money to upgrade my source as well, so i don't want to spend all of it on the amp.

I have similar problem with the 323. The nose of the volume knob seem to be only connected to the body of the volume knob via friction of the gear. Tipping the amp forward almost always cause the nose to fall out.
 
The 717, SRM-1MK2 and T1 that I have don't have that problem though.

Can the KingSound M-20 amplifier drive the Stax SR-407/507?

  Can the KingSound M-20 amplifier drive the Stax SR-407/507?

yes, but there are no safety resistors in that amp, so if you play it too loud
and it clips hard it might damage the headphones.

Thank you, Kevin!

Interesting. Do you know how old each of your amps are? I'm curious as to whether or not this is a new development, because I've had two people with older SRM313s say they haven't had the problem. Is your 323 a newer model?

Is it possible to glue the thing on? A bit of Epoxy mix glue should work.
