hello to all you audiophiles out there, \nI would like to know if anyone out there has done a oppo-203 mod with the oppo-mod from china using the linear power supply-SE VERSION and if so was there a difference in audio & video quality? is the purchase price of the upgrade worth it? as i'm considering doing the upgrade but don't want to shell out $360.00 dollars if the upgrade is not worth it. As you can see on the selling websites like audiogon, audiocircle and e-bay the discountiuned oppo player's like the udp-203 & 205 are selling at extremely outrageous over the top prices. i'm not one to pay triple or quadruple the price of a unit that was going for $1,299.00. I own four oppo player's the 105d,103d,103 and the 203. can anyone answer this question for me? it will be greatly appreciated. thank you.
