Sonic Frontiers Line 3 SE Tweaks

I have the standard Line 3 and have also replaced positions LV1 and V2 with Amperex JAN 7308s. When the Line 3 was first breaking in I preferred the stock Sovteks to the 7308s. The Sovteks later became bright and thin sounding with an emphasis in the upper mids/lower treble. Reinserting the 7308s made a large difference. Bass articulation improved, the bass became deeper and more fleshed out, especially the mid and upper bass, the highs were less harsh, and the midrange became richer, all without loosing the Line 3's linear qualities.
