gefski, what's your tube combo for the WA6 sir? I use the "Mighty" 596 rectifier with S/E 6SN7 drivers most of the time. For more midrange the Brimar rec is pretty awesome too.
For the HD 650, the Brimar + 6fd7 gives lots of life & sparkle.
For the RS1i, a pair of 7n7 is a graceful & relaxed presentation, yet with gobs of detail and terrific touch & texture. Surprisingly, I prefer a SED Winged C blackplate rectifier (1950s about $50) with these, having also tried Brimar, Mullard, & Princess.
Haven't sold enough stocks to acquire a 596.
