post #1756 of 4016

The 323S is a great amp. I listened to the KGSSHV and thought it was a bit bright in comparison. The 323S is surprisingly "just right" with the SR-009 and SR-Omega IMHO.

 

Not quite the SR-007 though...

Kind regards,

I think I've mentioned this but if you can find some SR-303's or the regular SR-404's ... I think you would be very pleased. Perhaps the smoothest Lambdas I've heard ...

 

The SR-307's (and I'd guess the 407's) are most likely not what you want ... they aren't necessarily bright in the high freqs (to my ear) but they sound sort of edgy and hard in the midrange ...

Hi S1rrah,

 

Thanks, getting a new SR-404 may be tricky and I'm reluctant to get a used pair from eBay. The SR-407 seems to have a slightly different specification to the SR-307 - would this make any difference?

 

Kind regards,

 

 

Martyn

I would think the entire "07" line would share the same, general, sonic qualities. This is the case with the 303/404 series and so I would assume it to be the same with the 307's family of ear speakers ...

I'm sorry, but this discussion is deranged madness. I'm saving up for one of these models and have been reading people's experiences with them.

 

The 404 and 303 are supposed to 'suck', being white-hot strident with an "impossible peak" and no inter-unit variation by the word of internet Stax experts. The x07 series are supposed to be 'fixed', and you tell me the previous series is smooth by comparison?

 

Did you mean your 404LE, or have you heard these?

 

I've looked at the data on the internet available for the 404 and 207. Alongside a small high frequency attenuation, they are identical to the thirty year old model!. Where are these defects located? What is their Frequency and BW Oct? Three minutes and a youtube sine sweep is sufficient. By mids do you mean 2 or 8 kHz?

 

As an aside, rates for second hand ebay systems are completely excessive. Averaging 75% of the price shipped of a 3170 to my country. That's for an srm-1 which has never seen maintenance and a lambda pro for which I must pore over photos if available for perforations and defects.

I finally joined the Stax ranks. Now a proud owner of of an SR-202 and SRM-252II  :)

That was my understanding as well (haven't experienced a lambda that did not have this etch though).

I did not ever read about measurability of the famous treble etch, my guess is it lies in the csd curve / transient response (some underdamped resonance(s) in the mid or or upper midrange) you wouldn't see anything in the typical FR charts if these resonances don't stand out there (look for ridges that appears after the initial decay of the csd).

There are differences in the driver tension that differentiates many (not all) of the lambda models. Among the current offerings the 207 is supposed to be the best (not my account), and I imagine by their used prices the 40x, 30x models you should be able to audition something that fits your needs.

 

You are looking in the wrong place if you want quantifiable data, and I'm not sure what you were looking for by reading people's subjective experiences with them? I'm sorry to hear about your import woes.

 

There is also a breakdown of the SR-507 somewhere that points out some structural frame/driver assembly changes that stax adopted over the adhesive-based(?) solutions of the previous generations. This is all from poor memory so take it how you will.

Good choice : D
He will give you envy to discover of other pearl of Stax : )

Don't know which Stax experts you're referring to but those that have owned, heard the whole lot here including myself would put the new x07 Lambda's on the bottom of the list. The 207 is a slight exception.

This is the only statement I would believe to be accurate regarding the Lambda generations.

 

Even impressions on the new Lambda line by the Don (where is he these days?) have flip-flopped over the course of one or two years.

 

I would say that the only conclusive way to be sure is to hear them side-by-side, but this is of course easier said than done.

 

This isn't just a case restricted to Lambdas either. Read comparative impressions between the SR-007 vs. SR-009, SR-007 vs. SR-Omega, and SR-009 vs. SR-Omega and you'll find the same complete absence of a proper consensus.

True. Proper general consensuses seem to be pretty hard to reach within the realm of stax and this thread.

I disagree...:tongue_smile: 
just cuz...

 

But on another note, 3X0 "The 323S is surprisingly "just right" with the SR-009 and SR-Omega IMHO."  So you would consider this a viable option for an interim amp while waiting on a TOTL (BHSE or the like)?

Had the 303's and now the 404LE's ... I find them very similar and not white hot strident at all. 

 

Also had the 307's very recently, for about three months, and did not find them white hot strident at all, either. I did find to be rather glaring in the midrange compared to the 303's and 404LE's, though. So much to my ear that I sold them pretty quick. 

 

White hot strident? I'd call Grado RS1's at times white hot strident ... and the GS1000's I had for a very long time and mostly loved to be occasionally off-white hot strident ... but any of the Lambda's I've heard? I haven't found any of them to be strident in the high frequencies at all. Just varying levels of "etch" in the mid range. 

 

I've found the 303's, 404LE's ... and especially the pair of Koss ESP-950's I currently have to be the least "etched" of any thing I've heard. And I haven't even started up the ranks of the really expensive Stax stuff yet.

 

Get the cans and decide for yourself mate.
