Bill Crane, Crane Home Theater muses:
"Absolutely the best 12AX7 tubes ever made. If other tubes kick it up a notch, these kit it up 5 notches! They are the best bang-for-the-buck mod to the Jolida JD-100 and are compatible with other mods. They bring the already sweet sounding JD-100A up another level to compete with $3K+ CD players. Gives most CDs a near-analogue sound with no exagerations, just the music as it was recorded. The Allegro 12AX7B's have been in my ARC SP-3A pre-amp for two decades, and they still sound great! This is the only way to hear the wonderful sound the JD-100 CD player is capable of producing, and it is the only way I sell it."
