^ I know this is waaayyy old, but did it work for anyone?
-K
did you mod yours?
No, not yet.
Checked into it w/ an engineer friend of mine and he said to do it because the BurrBrown IC's have better specs. It's not going to make it a V2 or anything, but should have better results that the stock IC's.
For a "second opinion", I asked Richard (PoorlyConditioned) about this upgrade. He said he did this upgrade with "THAT Semiconductor" IC's instead of the BurrBrowns. He said that he didn't really do enough tests to know if it improves or not, but thinks the stock setup is quite good, anyway.
I'm told that the "THAT" IC's (1500's???) are better than the BurrBrowns, but you have to purchase them... $2 something and a min order of 50 so, I settled for the free BurrBrowns. I ordered free samples following the information in this thread. Planning on doing the swap this week since I'm rolling for MMW/SCO in Philly on Saturday.
Whether or not you hear the difference is another story... depends on playback system to really hear a difference I would assume. Planning on doing a quick A-B test w/ a test tone generator or something when I get them...replace only the left channel and leave the right alone to do the test, then install the other after. It will be intersting to hear if there's a difference.
