Hello, I just got my Wadia 830 back from Mr. Huntley, and am very pleased with the results. I had the "reference" mod performed, and I must say it was worth every penny--stayed up till 1AM last nite listening, and it's been a LONG time since I've done that! The improvements noted above are accurate: smoother, more transparent, and greater extension at the frequency extremes. The bass improvement in particular is outstanding. In addition, the sound is noticeably more analog in qualtiy. Overall, a spectacular improvement. (BTW, if you do business with Steve, tell him that Dan C. said you will be expecting a "reference" power cord with your package!) Best Wishes...
