guys, few questions to ask before i'm gonna buy SRM-T1S (100v japan version). is there any guides on how to convert them into 220v? or should i use them with a transformer? would it affect the sound quality?

thanks in advance

I am wary even about ferrite clamps around power cables.

Trying to use my SRM-727II with voltage transformer (it was made for 117V originally) I've noticed that the lack of power causes loss of control - boomy and dominant bass, insufficient highs, muddy and unfocused sound, the opposite effect of what I hear now (so I had to change the internal power supply for 240V).

is there any ways of modding the power supply of SRM-t1s? any helps on the guides would be much appreciated.

Edit:
just found out some guides on this page:
http://www.head-fi.org/forums/f113/s.../index692.html

could this method apply in SRM-t1S as well?

changing voltage should be fairly easy. there are a few different systems so if you provide a picture of the inside of the amp you can get a useful answer.

95% of all T1 amps (T1S and T1W too) have a switch to change the voltage hidden behind the bottom panel. Just pull out the plug and insert it with the arrow pointing at 240V.

i have got to ask him to check the inner part of the amp.

if there isnt, could your method as shown in page 390 be applied in the amp?

thanks for helping me out mate.

Is it bad for the 'phones or amps if you plug or unplug the 'phones from the amp when it's on?

That's also the reason why you can't hook up two active sources to the amp at the same time. It could be that you get an inverted signal on the RCA loop out but that's not really a problem. (Depends on the XLR pin configuration.) 2. When the volume control is off, it's bypassed, so there is no attenuation. According to the Stax site gain would thus be 54dB.

Cool!

Almost all of the amps can be rewired manually so yes.

Can the other Stax amps be easily be rewired or have a switch? Like the SRM-006tA?

Yes, didnt you see the post above yours?

What are the amp possibilities for the sr-303 headphones? I don't want tube amps.
Are there any "cheap" class d amps for the stax? The 323ii is too expensive, and i'm afraid the quality wouldn't be high enough.

 

[plaidplatypus]

There is an affordable SRM-313 in the FS section right now.

A SRD-7Pro adapter might cost you that much by itself.

The newer amps can be tricky as Stax often cut the 117V windings which means they can not be changed from 100V without some very creative soldering and some luck.

I just got Lambda Signatures but somewhat damaged. The grill was poked in on one spot. The dust cover membrane has a dent and will wave in that area. Does anyone have experience with electrostatics to know what damage is bad and what is really bad for the sound. It was poked in pretty good but I don't think it reached the stator if it dented that would sound be unlistenable? I am going to go find something like a leather cleaner to clean the pads. The sound can change a whole lot just from head position with these headphones. If there is a hole is the dust cover should it be easy to notice listening to them?
