@gte357s What output tubes using in 211 and 300b. I was using Shuguang Black Treasure in my 300b amps until recent change to Psvane Acme, much more color with the Acme, Shuguangs bleached out in comparison. My 845 has also benefited with better output tubes.
Based on your comments as to airy, open vs warm, bass heavy I'd not change out major components at this point. Sounds like your close to your goal, small changes will likely get you where you want to be.
Change in output tubes, and/or cartridge may be all you need. Change in power cords may help as well. Clean AC important as well. When you get to the level of equipment and resolving powers your at, little things can mean a lot. Looks to me like you have all the fundamentals in place, just need to tweak a bit.
