My A/B is gonna be a bit simpler and easier. I'll be comparing the lows, mids, and highs vs the Fiio E9 as a reference point, as I know the strengths and weaknesses of the E9 compared to the stock Lyr tubes. The stock tubes are recessed in the mids and have slightly less sparkle, and the bass is more refined and controlled, but less prominent, but with more punch, and more natural, thicker tone. Going by what people are saying, the Valhalla tubes should have more prominent bass, more mids to push it closer to the E9's, and even less sparkle. Time will tell.
