Hey Steve, There's a huge smile on my face right now, knowing that there must be a huge smile on your face right now. I'm so glad you're enjoying the 220EX! And, I have to hand it to you. You wore Vince down, no mean feat! Now you can enjoy the 220EX always. I just finished my 220EXmod, and have just started taking it through the burn in process. I'll post some impressions after I give it some time. But, I'm going on memory as to how the modded version sounds compared to stock. As you listen can you post A/B comparisons between 220EX and 220 stock?
