True but you can't exactly compare the two as it is a bit unjustified. Manufacturers can do an ortho, i.e something that sounds good for cheap and looks good to boot. The problem is they either don't want to because they don't have the expertise or equipment to do so in the field of planar magnetic technology or they just can't justify it because there isn't enough demand and even more so why bother with something less expensive when you know customers are paying more for something else, they are making ends meet with $ anyway.
The T50RP is a piece of crap, until you get it properly modded and measured then you'd be looking at over double it's price easily, but what about time and effort? Those things are priceless. It's butt ugly as well.
