One is a redesign of the KGSS with a new PSU. The other is something completely new and would be in the 10k+$ region for a commercial product.

Hi,
I just registered to head-fi because I'm restoring my Lambda Pro and SRM1/II B-Type. Therefore I have some questions.
A german dealer recommends to switch Voltage input from 220 to 240 because of increasing Voltage(230 and more) by the powerplants in the recent past.
Which max input Voltage is critical for the 220V setting of the SRM?
TIA

 

[spritzer]

There is no set rule for this but it's easier on the amp if the input voltage is equal or lower to the mains voltage. There isn't a regulated PSU in any of the Stax amps so any changes in mains voltage will be multiplied by 1.4 over to the internal circuitry.

 

[kodama]

Do you have any values for adjustment the amps or at least MPs on the pcb? (this thread is a little overcharged)

 

[spritzer]

Here are the correct voltage settings:

There will be some new SS amps in the future but they will be very expensive indeed and I'm not sure anybody will build them commercially.

if you actually do end up building the 2000v swing dc-coupled SS amp, I will be the first in line to sell my BA and R10's for it!

Dear Audio-sensei/gakusei (teachers/students),
I live in Japan and can get stax for relatively cheap. I can get the stax 3050II system for about 830.00 usd here. I think I also have the ability to get a 404 le. I could save some money and buy the 404 le with the 323ii, the regular 404 with the 006tii... I really don't know where to start. I listen to a lot of orchestral music, but also enjoy jazz...mostly acoustic music. I've tried to gather a consensus by browsing the depths of the head-fi caves, but this adventure is similar to bringing the ring to mordor. Please help relieve the burden so I can (here's where the lord of the rings analogy falls apart) obtain my precious! Thanks in advance!

Buy the SRM-1/Mk2 used on yahoo auctions and the 404 LE.That would be my choice.

You should also consider an SRM-T1 like this one: SRM-T1 @hifido
Great match for most Lambdas.

 

[PianoForte]

I think I've read this regarding stax's older products, but just to confirm, the general consensus is that the SRM-T1 and SRM-1 are generally considered better than the newer amps?

 

[padam]

Yes and of these two the SRM-T1 which is better however a few phones might match the SRM-1 Mk2 Pro better, the Lambdas are generally better with tubes thrown in. The current SRM-006tA is quite similar to it but the parts used are not quite the same so the SRM-T1 is considered to be a bit better sonically.
The newest amp, the SRM-600 Limited is probably better than an SRM-T1 because they switched to better tubes which also added a bit of power but it is very expensive.

Has anyone of you fellow Stax nuts heard about the SR-404 Mk2 yet?

I had a SR-404LE on order in Germany, but unfortunately all the LE's are sold out. Now the owner of the shop offers me a new SR-404 Mk2, which he claims sounds identical to the SR-404LE.

What's up with this? The Stax site doesn't list it yet, nor can I find anything on the interwebs about, mainly because all the search results are filled with '404's and 'Mk2's that are not what I'm looking for.

 

[padam]

That is a logical step to take, however it could hurt the SR-404LE's value if the Mk2 will be as good as the LE.

 

[TimJo]

I suppose the LE's could get rebranded after the first 1000, and maybe they aren't that limited after all.

 

[catscratch]

I sure hope they update the 404 and fix those mids. But I haven't heard anything on that front either.
