the UltraCap supplied wallwort is rubish... feed it with a decent power supply... noise spreads trough the ground plane... the alternating circuit that switches caps banks every few seconds must have a common ground linking both banks... so, we are talking about the power supply of the power...

To me they do not sound the same at all… some people may argue that there is no difference, but… as I always say “there is no difference and I HEAR no difference, are two totally different things”… if someone can hear the difference someone else is not hearing and CAN point that difference in a...

Even if someone has, comes to my head that issues about "sounding" should be heard not necessarily measured... am I right? ;)

Yes, and actually its an outstanding sound card. If you use it with a good sound program as JRiver or any other that can handle ASIO output (2i2  has native ASIO drivers) and set it to resample the output to 96000 the result is top notch sound. Maby, just maybe, you may need to add some EQ...

To me, it comes always to the same point.   Fidelity, in an electroacustic device, is due to the electrical signal provided, not to te original event.   Since the original event is recorded from a subjetive point of view, in a particualr enviroment, with a particular mic...

My MOD is focused in simply removing as much of protective plate as possible, I dont like solid difractive objects in the way of the sound. Holes are not very neat, but again, in difractors realm, very regular shapes are not my cup of tea.  After I made the cuts you see in the pic I dumped a...

"I guess all it comes down to is, what is the best combination of driver and control panel?"   ... and also, maybe,  a new set of instructions, as the ones in the first post are totally outdated and some links lead to nowhere.. and when thy lead somewhere Windows 7 (32bits in my case) wont...

  One of our readers owns a pair of STAX Earspeakers with a STAX SRD4 adaptor . Due to overload a pair of resistors in the SRD4 burned up, so badly that it is impossible to determine their value. Would any one be so kind to, ideally, send us the schematics of the SDR4 adaptor so a repair...

I have a problem with a SRD-4 adapter: 2 resistor blown up, so badly that there is no way to know their value. Any positive information about this? (pictures of the damaged zone in my photo album) Thanks a lot :)

great work!
