PS1000 won't be better than T1 imo. especially with the WA2, it'd be quite tough to beat. even with LCD-3 and TH-900, T1/WA2 is still my favorite or 2nd favorite now. its just such a good combo, definitely endgame quality with the right tubes.
u could upgrade D7k to TH-900, its a pretty good upgrade
and T1 are better than HE-500 though the HE-500 are very close to the T1 now that i upgraded my DAC.
