JWM - I made exactly the same change to the drivers in my Phi 300.1 as you did - the Sylvania's in the input position (3/4) lent an edginess to the treble. They are now outputting the signal from the RCA's in the center, and as you say -- my oh my ! Just for giggles I damped the Sylvania's with brass rings - that seemed to add solidity to the images PLUS made a really cool angle out from the two volume knobs in the front. Looks matter too !!
oh and ps -
do you have any experience with the Shuguang CV-181's ? I did briefly replace Kevin's stock tubes with the Golden Lions and HATED them, returning them even tho I took a loss. Grand glorious tiring Hi-Fi is how they sounded.
