Yep, it's cold, only two hours south of Winnipeg here, but I am a polar bear and like it that way. Speaking of the Winnipeg, I need to put a bug in their ear to get another meet set-up...

It's not that bright actually, a far cry from the piercing blue lights. That said, when I order a new batch of these custom made switches I'll probably have them orange or something like that.
My wife's from Winnipeg (Manitoba) and with Minnesota plus North Dakota, the coldest places I've ever been.
Here in Chicago it can get quite cold, though not as often as Minnesota. Also, we can -at times- get an awful lot of snow- there's a lake effect that can get set up and dump huge amounts of snow on certain areas hereabouts. I am still fighting with insurance companies and contractors after the huge snowfall of Feb 2011 collapsed part of the roof of my warehouse. That was the day that hundreds of motorists were trapped by snow on Lake Shore Drive. http://chicago.cbslocal.com/2011/02/01/officials-shut-down-lake-shore-drive/
When it gets cold, I wear headphones.
That's George. He's a great guy. I bought my KGSS from him. Very nice fellow. I should shoot him a PM about a mini-meet: KGSSHV, T2 and your BHSE.
Woah, be careful there.
Linearity in tube designs is not approached nearly as easily or as affordably as it is with solid state designs. Maybe if we're talking SETs but you need to be more conservative with the verbiage.

I'm moving to Winnipeg next month. If there is a meet, feel free to drop me a line.
If you can get one going in the late spring, we're there visiting my wife's family.
PRO: A well-extended flat frequency response & clean transient characteristic. The pair is extremely well-matched. Not much of a step up from SR-Lambda Professional, but the performance is great nonetheless.
CON: A good acoustic seal is vital for sound reproduction below 100 Hz. It is such a shame that the cable is not replaceable.
ON SECOND THOUGHT #2: Stax SR-Lambda Professional can be paired with its proprietary equalizer unit, ED-1, to simulate an accurate diffuse-field sound. Moreover, ED-1 can be used in conjunction with SR-Lambda Signature as well. The simulated result is a somewhat downward-tilted diffuse-field characteristic, which is more suitable for general music listening, as some listeners find the true diffuse-field target to be overly bright and harsh.
ON SECOND THOUGHT #3: A free-field analysis has been carried out at various locations within the frontal volume of the housing using an accurately calibrated microphone. The test result suggests that the entire surface of SR-Lambda Signature's diaphragm is not behaving as uniform as originally expected, but definitely more symmetrical than that of SR-Lambda Professional.
ON SECOND THOUGHT #4: By default, this headphone is far from the Olive-Welti target, meaning that the tonality is simply too harsh to be considered as hi-fidelity. A substantial amount of equalization is needed here just like the predecessor, SR-Lambda Professional.
PRO: A well-extended flat frequency response & clean transient characteristic. Can't get much better than this.
CON: A good acoustic seal is vital for sound reproduction below 100 Hz.
ON SECOND THOUGHT #2: The proprietary equalizer, ED-1, turns Stax SR-Lambda Professional into the most accurate diffuse-field simulator ever made, with better accuracy than Etymotic Research ER-4B by effectively neutralizing some deep-nulls and peaks.

However, an accurate diffuse-field headphone may sound too harsh & bright for some listeners, according to Olive and Welti. If that happens to be the case, coupling ED-1 to current SR-lambda based models should resolve the issue, as they have a slight attenuation in the treble. The consequential spectral balance will be close to that of a downward sloped diffuse-field target, which will be more comfortable to listen to.

PRO: A well-extended flat frequency response & clean transient characteristic. Without a doubt, SR-207 exhibits a good electroacoustic behavior within its entire frequency spectrum just like any other Lambda series models; Thus, it can be considered to have a great economic value.
CON: A slight channel mismatch above 1 kHz & inverted polarity. Again, a good acoustic seal is vital for sound reproduction below 100 Hz. It is such a shame that the cable is not replaceable.
ON SECOND THOUGHT #1: Above data clearly shows the difference between Professional, Signature, and SR-207: As expected, compared to the other two, SR-207 is further damped by a few decibels in the treble for less harshness with its lower/higher ends further extended. Here's a rule of thumb for STAX headphones: The more recent the model is, the wider the frequency bandwidth becomes.
ON SECOND THOUGHT #2: Just like any other Lambdas, SR-207 turns into an accurate diffuse-field synthesizer when it is equipped with STAX ED-1 equalizer. The simulated result is of a slight downward-tilted diffuse-field characteristic, which is more suitable for general music listening as some listeners find the true diffuse-field target of Professional to be overly bright and harsh.
ON SECOND THOUGHT #3: A free-field analysis has been carried out at various locations within the frontal volume of the housing using an accurately calibrated microphone. The test result suggests that the entire surface of SR-207's diaphragm is not behaving uniformly just like any other Lambda series models, if not worse. The frequency response magnitude variation occurring at the polarized resonance frequency, 180 Hz, indicates the diaphragm's stiffness has been slightly increased from that of the classic models.
ON SECOND THOUGHT #4: Just like the other Lambdas, this headphone is also far from the Olive-Welti target. A substantial amount of equalization is required to match Harman's target response.
