Latest version of the chopped down version of the drivers - newer than 1.71 (most files are took from an Audigy 4 Pro update (same drivers for most of their cards - yuck) on Creative's website and are dated 04/04/05) is here: RAR: http://rapidshare.de/files/1518876/E..._2005.rar.html ZIP...

Just tested on a new XP install/1212m without any hiccups so they should be safe to use.

Loading PatchMix without Effects Delete CTEDSPFX.dll file in the system32 folder or any other instance present in the Windows folder and subfolders. -------------------------------------------- Or, I also 'put up' a VERY chopped down version of the 1.71 drivers - only tested on the...

Not really a mod, but here's my 1212m "minimal" session for use with FOOBAR/ASIO/44khz (attached).

I finished modding my card (caps modded as in the pics in this post http://www4.head-fi.org/forums/showp...3&postcount=10), and only after a day or two the sound is magnificent. For opamps, I settled to OPA2107 (locally bypassed between the rails with 1.5nf mica - VERY important tweak)...

Regarding burn-in, I have found the same things, the 1212m really sounds better after a couple of days inside the PC. Regarding the on-topic subject (changing caps/modding, the capacitors will be here tomorrow so I'd better get a camera ).

I have the card hooked up to a pair of Infinity Reference Standard II speakers (old classics dating from '82 which I recently put through a rejuvenating process as in crossover/production wiring reworking, bass drivers refoaming and further cabinet strenghtening) and I like the soundcard very...

Sorry to hear that the mods sound rather bad... From my experience, use OSCON only for digital bypass/decoupling. For analog decoupling OSCON tends to sound too dry, even on the harsh side and a little bit too thin. It keeps details but it really kills dynamics and any sign of liveliness...

Also of interest is the c64 capacitor on the digital board. Situated on VR1 out, I think it feeds the two oscillators U7&U9 and the chipsets. Voltage is 3.3V or less. A large value OSCON here should help tame the bright character of the board.

The small SMD capacitors are X7R ceramics 0.01uf (1nF).

Information about sound signature and performance of various Low-ESR capacitors: http://www.diyaudio.com/forums/showt...436#post604436 You should check the entire thread, it's a good read.

I'll leave the card in until next week when the capacitors arrive, but if you're right there are three reasons why that cap should be changed too: 1) A capacitor not only filters DC power for a certain device. It also acts as a reservoir and keeps the rest of the supply circuit (which also...

If you're using the digital output from the 1010 card here's what I think a part of the $500 Empirical Audio mod ("removing some filtering elements") consists of: Basicly, just bridge the two inductors and remove the filtering capacitors. Downside is that your card won't pass FCC...

I changed some things around on the above pics, I tried to keep most of the small capacitors within a reasonable 6.3mm body and <2.5mm between leads in order to keep all components on the solder side. Will update with data as soon as the caps arrive from Farnell UK. Some other 'tweaks': -...

Basicly, I just got my 1212m and I did a bit of photoshop in order to do solder work only once. I won't go "over budget" with the caps, so I chose Panasonic FC (sounds relatively good and is cheap) for the PS/analog section and SANYO SEP for digital (I can only get these at Farnell). So far I...
