Today I ordered the $249 "Enhanced" version of this transmitter. I already have a V5 that is not "enhanced." I will do a side-by-side comparison for those who are interested for both audio quality as well as range. Not scientific by NYC standards, but a better than guestimate for those who might be toying with the idea of buying one. Based on UPS shipping from New Jersey, I should see it in Florida by Thursday.
Out of the box the unmodified V5 had the old Illinois company's label on the bottom. The audio was/is not great for music. However, running the ABN Old Time Radio was adequate.
The older V5 with the antenna fashoned into an inverted L around a window at ground level, could be heard on the fringe at 1600 feet. So I am guessing that with the antenna vertical and outside the performance would be better.
Will keep you guys posted.
