Headphones are still in the same condition.  I re-soldered the connections to one channel and it helped with some of the issues (mostly the intermittent connection).  The static is still there and it does not seem like much can be done. 

Thanks for help.  I've posted in both of the suggested threads.

Thanks for the info.  Anyone have any luck opening up their lambda pros?

I picked up a set of stax lambdas and and srm1-mk2 inexpensively.  Since my last thread, I have had the amp restored (re-soldered and modified for pro bias).  My sr-30 sound clean.  My lambdas still have significant buzzing in the left channel at both frequency extremes.  There is also a...

Is there software that you would recommend and is compatible with what I already have?

I have been very happy with my dac/amp combo (odac->hot audio thunderbolt)  for listening to music from my computers.  I use both a laptop and a desktop so the usb connectivity is nice.  I've recently switched from PS3 gaming to computer gaming.  I do not currently have a dedicated sound card in...

Yama's replied but as I expected, not much can be done for such and old set of headphones.   What can I expect to get for the lambdas as parts?  They right driver is still good.   Can the srm 1-mk2 power newer sets (sr-207 up to sr-407)?  

No reply form the seller so I'm assuming that means no return option.  I am fairly sure the amp is good which is a relief because I can sell it a recoup most of my investment.  Is there anyone that does repairs on the headsets?  I emailed Yama's but based on the reviews here, I'm not holding my...

Update: I let them sit for a while longer and the sound has improved again in general.  Still getting vibration out of the left side.  If it is dust, can I somehow clean it out? (compressed air or something?).  There is also a channel imbalance.  Will correcting it with the volume knob be good...

What I meant was that the google search kicked back an image that said "professional" on the top for the pro bias model.  This one doesn't say professional and both plugs are just labeled "Earspeakers".     It seems like this may be the source of some of the problem.

Deadlylover - Thanks for the tip.  I plugged them in this morning and left it on all day. The sound is significantly improved now.  It now sounds more like distortion, specifically at high volumes.  It's still mostly with bassy tracks.  Is this due to the pro/normal mismatch?

Any Stax gurus?  I hate to press so hard but my buddy is leaving on sunday so I need to make a decision quickly

I just got my Stax gear (SR-Lambda Pro, SRM 1-MK2, SR-30).  I excitedly plugged in the lambdas but to my disappointment there is static on any bass note.  It's especially bad in the left ear.  The SR-Lambdas are professional but there is no label on the amp.  I'm assuming this means it is normal...
