Thanks for all responses. Surely useful.
Yes audphile, there may be a possibility that the amp is connected to the power conditioner just to experiment if it will sound better going through it or directly to the wall outlet. The wall outlet will always be available for the amp. The thing with the Furutech DPS-4.1 is it’s significantly costlier than the TCS31, and I have not factored in the plugs. My actual budget is actually at the FI-28 (R) and TCS31 level. Going up to FI-50 NCF (R) and DPS4.1 is quite a stretch (it's 3X the cost I think) and would have blown my budget. The advice is appreciated though.
