I had been traveling quite a bit in February so didn't get a chance to try out different tubes. Finally got around to ordering new tubes from Brent Jesse as per @avanti1960 's suggestions. Was advised to get the Amperex (1960) for the center/preamp as suggested on this forum. But Brent suggested that I go with Amperex for the AX7s as well. He also advised me to let them burn in for at least 48 hours before doing any critical listening.
So what's the verdict after changing 3 tubes? All I can say is, wow! The sonic improvements are not subtle by any means. I'm getting much more detail than before without any harshness, all in a very polished and smooth package. Better tonality, more separation and air between instruments. Much wider and deeper soundstage. Vocals sound more natural than before.
But the biggest improvement by far is the quality of bass. I never thought I could get the P3esr's to produce such satisfying base. It doesn't go much deep but whatever I'm getting is tight and very palpable. I was thinking of adding a subwoofer, but honestly at this point I'm not sure I need it. Everything sounds so balanced, don't want to ruin it.
Another improvement I noticed is that I'm getting more details and bass at low-to-moderate volume. Before, I had to crank it up to 11'o clock to get the details and bass. After the switch, everything sounds pretty good even at 9'o clock position on the dial.
Thanks everyone for the amazing advise. I'm pretty happy with the music this system is producing. I'll probably swap the remaining AU7s in a few months, and maybe get a copper-based speaker wire to see if I can eke out even more improvements.
