In my opinion I felt the GLite was more refined and effortless with a quieter background. The M-Stage was warmer with a little more bass impact. Even though I preferred the GL, the choice is yours as they're both fine options.
@ $300 if you can find a Gilmore Lite it will trounce the fiio. It's not even in the same league.
But the Gilmore lite has been discontinued... which IMO takes it out of the comptetion.Is the E9 superior to the matrix m-stage?"
The GLite is readily found on the Sales Forum. If you can buy one then it's not out of the competition.
