I went with WBT. After all of the years of dealing with the old strips on Mac amps, it is such a pleasure. Of course, I lost the option for 4 and 16 ohm connection, but my speakers are 8 ohm, and I 've also used my Mac with 4 ohm speakers with no problems.
I know that most people would never consider doing that because of resale value, but I have no regrets whatsoever.
