Yeah man, it's all just hype. I do TB because it's what everyone wants/expects, and it's actually the most convenient for me to do.
Yeah, John's got it right. Boss may be cheaper, but it doesn't mean they always sound bad. It just means that there are some that are even better than them. The buffers just control the quality and impedance +/- capacitance of the signal. [keeps the signal true even over long distances. This is why the guys with long cables and all TB boards buy True Bypass Buffers...

I promise I'll make a fortune off of that one day!

] But not all buffers are designed equally, even though it's the same principal.
