I have three different op amps in my possesion that I am still waiting for a time to try. OPA2227, OPA2228, and the OPA2107.

I found a very promising opamp reccently released from National:

Should be even better than opa2134 by BB (on paper ..)

have you heard this OpAmp yet? Any reviews on it anywhere?

Cool. When I get a chance I will have to check it out. I still haven;t even tried the others yet. I got some 2134's the other day too. It's goign to be at least a month before I can even get a chance to listen to these.

Hey PPL,

Thanks for the Review, theres kinda nothing out in the www about this precious card... got a new SoundSystem and now i need a capable Soundcard for this....

as i think i don't need eax and stuff for gaming and dts +dd can be made by sw or optical out, i think this could be my solution.

I read here about that OpAmp stuff (never heard before & www gives no good explanation about why+how to use hifi-opamps...) and i think i can manage this (maybe s.o. can spare a minute to explain it to me?! )
I'm i HiFi modding newbe so.....

BUT:

Here is a list of opamps that were said to improve the sound of the Prodigy I found in another forum (I will post the link once I find it again).

-OPA2107 (More accurate bass and fuller sound, not as bright)
-AD825
-AD8610
-AD8620
-OPA627

[...]

i found your link to the forum, hope it can help some of you... ;-) :

try the AD825 opamp, it's very good compared to default opamp OPA2134 (on prodigy 7.1 XT). but since AD825 is mono opamp, you will need 2 of them and use browndog adapter to fit to 8 DIP socket..

the prodigy 7.1 xt card is like this (default):
the OPA is for 1/2 channel
the JRC is for 7/8 (headphone) channel






the modded prodigy 7.1 xt card (AD825 at channel 1/2):






i already ordered AD8610, will be test it soon...








DURWOOD -> can you attach the prodiy 7.1 hifi control panel picture? the 7.1 XT control panel is like this:

kapt - this forum has a feature where it moderates all new posts from users with under 5 posts. This doesn't mean your post isn't there, it means it's waiting for a moderator/administrator to approve it.

I deleted the other 2 of your posts as they were duplicates.
