The only differences in specs between the Temper-V and the Orpheus(I know it means little,but interesting anyway)is a very small difference in internal impedence,and a slightly higher output and new body style,in the Orpheus.I hope the slightly higher output did not tip comparisons in favor of the Orpheus.I'm fairly certain this was NOT the case,in the comments from those hearing both designs,but believe me I've seen stuff like this before.
Best!
