The Stax thread (New) - Page 762

The 4070s are said to be quite hard to drive so go for something more powerful if you can. Also worth mentioning that it has a 'studio' kind of sound that you might or might not like (for example with studio monitors, bad recordings will sound crap).

mmm... the bad things is that there is no way to listen them in italy. For something more which driver unit do you suggest ?

SRM-717 is probably the best Stax amp after the unobtainable T2. The 727(ii) might be good as well (it is not the best for the O2 but it could be good with other phones like the 4070) and there is also the 007t(ii).

You are really killing my wallet man

One thing to note is the music used to power the SB units matters. The bias supply needs at least 100VAC to power up completely and if you are listening to some quiet chamber stuff then there simply isn't enough. The power is drawn from the audio transformer secondary and then fed through another transformer but that may simply not be enough. Another thing to think about are the amps used. Some puny switching amps simply don't have a lot of voltage swing compared to Class A behemoths. A Krell Class A amp has roughly 200V P-P of swing and can drive the phones directly...

What would be the best tube amp from the stax line to pair with an O2MkI?

lamdas,srd7-sb and audio-note oto-se

I bought the SR-Lamdas and SRD7-SB recently for sale. (I am in Mineeapolis, for the next two months, where it is impossible to move very far in any direction without running into a lake, leaving behind the all-hot, all-dusty and all-beige middle east for some cool, clean and green, not to mention the comparative ease of buying and selling.) I want to pair these with my older Audio Note OTO-se amp, which puts out 14 very nice watts in class A.

I like tubes behind the staxen and im hoping this will be enough to decently power the vintage LAMDA phones. I brought my other normal bias phones along, the 5nb golds, for comparison.

I am a Lamda Pro fan, which I use happily back there with my oo7t, not really perceiving the mid-range suckout people talk about. I am anxious to hear other lambdas esp the lambda nova sigs. Ive come a long way from the 34 electrets, which still sound good. I really like electrostatics!

That would be the SRM-T2.
For in-production units it would be the SRM-007tII (SRM-007tA).

A used T1 can be a good budget choice (similar to the 006t only better parts but basically the same) but it might struggle a bit with a 4070 (Spritzer wrote it in the past that it sounds fine if it is used on medium volume).

did I post this in the wrong place, or does no one really have an answer on this.

Maybe 300$ and 400$ with the amp. But, you might have trouble sending it in if there is a warranty issue (squealing noises, etc.) so I wouldn't risk buying one without an amp if I were you.

Yeah, I have sent mine a week ago and the were asking for the whole package.

Thanks. A friend of mine wants to get a tube amp for an omega setup. I guess he most probably found a 007tII in Hong Kong, as T2 seems to be very rare and expensive

Well-made aftermarket amps like the Woo Audio GES or the upcoming the WES might be very good as well, although I read that the GES struggles a little bit with power (but the 007t isn't the most powerful either).

Hey guys,

I have some older Stax SR-5. Recently I had some problems with them. I contacted Accutech and they can't repair them (they won't repair drive elements).

I've disassembled them and taken a peak. One driver has holes in the actual mylar film between the stators. Also, the same driver has the plastic on top ripped. It's not mylar, but rather crinkly clingy stuff. Any idea what that's for? Is it dampening, dust protection . . . ? It seems like it'd be safe to remove, but I rather not touch it till I'm sure of the function.

Anyway, does anyone know someone that would be able to repair the drivers? If not, any good supply for the proper micron PET Film/Mylar? Shouldn't be too hard of a fix.

Thanks!
