While still slightly on the forward side, the SR009 is much smoother so they are not that similar in my opinion.
I doubt that there would be considerable sample variation, more like different systems.

I have some Lambda Pros and an SRM-006t coming in this weekend hopefully. I think I need a step down transformer right?

Anyone got any thoughts on Lambda Pros?they are the original from 1984, ithibj and also the 006t is the older version

No thoughts as long as they work, no channel imbalance or damaged dust filter that can cause squealing, sit back and enjoy the music. The 006 according to schematics from the Stax Mafia is pretty much a modernised T1/T1S, it will balance nicely with the Lambda Pro's.

I've never flip-flopped with the x07 range, they were awful from the day I received my first 507 with the 207 being the sole exception.  They aren't perfect (too bright/forward as all the new models are) but come closest to the ideal sound signature.  Dirt cheap too... 

Yeah, I had this argument with DefQon earlier and he was right about your present opinion of them.
 
But I summed up the tidbits here. Your seemingly positive impressions seemed to have been from late 2010 in "that other forum" whereas your posts from 2013-onwards here have been pretty negative about them.
 
Thanks for confirming your present opinion of them.

Following my previous post, is there any easy way to change voltage on my 006t. I don't want to always use Thant massive step down transformer, the amp itself is big enough lol

Like all Lambdas, they have their good points.  The bass on the new Lambda's is the best from any stock unit though the comfort on the 507 is the worst of the lot.  Even the Lambda Pro do some things well but in the end the flaws are just too grating to enjoy the set.  Same thing applies to the 507, that midrange shout and general bright nature means they aren't what I'd call good.  Anybody who thinks the 507 is worth their asking price should try a fully functional LNS.

Can the SR-252 power the SR-407 to it's potential?  Also is the SR-407, Lambda pro level quality or is it way less?  What is the difference between 407 and the Lambda pro?

I'd go for the SR-207 instead. The higher SR-x07 headphones are supposed to be unbearably bright and harsh.

The SR-407 is neither bright nor harsh, at least not from the 006TS. Sounds absolutely beautiful and much better and smoother than all dynamics I've listened to thus far.

307 is definitely bright and etched on T1, though not harsh

 

[SilverEars]

You guys haven't answered my question.  I've heard Lambda pro is great value, and I was wondering which of the X07 is the same level as Lambda pro.  Also, so that means if the higher levels are brighter than the 207, I could be content with it until I do a leap to 007 or 009?
 
207 comes with a wimpy amp, does a better amp do it justice? 
 
Would the SR-252 under power the 407?

 

[davidsh]

If I would buy new it'd be a 207 and srm323.

Without going further into why and such, the people in this thread and other Stax threads are infamous for not answering too many questions etc.

Question:
 
The SR-007 has reduced capacitance over lambdas, meaning the current required to avoid clipping at 20 kHz for a given volume is also less than lambdas.
 
Why then, is it said that the O2 'wants power more than anything'?

 

[realmassy]

How can people find the 507's warm sounding, What?

It was never bright for me either, or cold/analytical. Lovely headphones and timbrically close to the 009. In fact the 009 are brighter (but never too bright). The only problem with the 507 is the monitor-like sound.

In all seriousness, why are all the new lambdas so bright? They are supposed to be the pinnacle of audio. Is this signature preferred in other parts of the world or something?
