Default Audiophile Sound Card

Hi all,
We have developed a very nice sounding PC Sound Card. We used the Audiotrak Prodigy HD2 as base and we have changed the op-amps by Burson Audio Discrete Op-amps. Also improved the power supply and the result is excellent.
You can see the card here:

We have a special offer for the diyaudio community:
For the 2 first people that order our Audiophile Sound Card the price will be 200 euros, including shipping costs to anywhere in the world. The only requisite is to open a thread in diyaudio speaking about the results of the product.
You should contact me first to make sure that you are one of those 2 people.
Best regards,
Paco

Question, what did you do to the JRC opamp output of the headphones? is there any modification coming for the headphones out?
Also did you keep the muting transistors in the signal of the output RCA ?

I'm curious what drove the decision to use the discrete op-amps rather than a quality audio op-amp, such as the LME49710, OPA1611, or the like. Do you have measurements of the THD of this modified sound card?

Hey man... I talk to myself all the time. I thought the logical extension was to do so on DIY Audio as well...
