Triode Wire Labs or NRG Custom The Five for my 300b SET tube amp?


So currently, my Cayin HA-300 300b SET tube amp is powered by the Morrow Audio MAP3 power cable, which I think is quite a good cable with a smooth, neutral sound fairly wide soundstage and very nice vocals and detail. I listen mostly on my LCD-3 headphones and my DAC is the Chord Hugo TT2. I also have the Western Electric 300b and Sylvania 6SN7W metal base tubes on the HA-300.

What I'd like is a bit more dynamic punch and meat without sacrificing resolution and soundstage, as well as not going too warm or too cold.

So I'm looking at two power cables, the Triode Wire Plus Seven Plus or the NRG Custom The Five. Also, is there a good reason to go with the Ten Plus or The One since the 300b tube amp?

I'm not interested in proving they're fake or not. On highly revealing systems I have heard the difference, and I've heard it between two cables on mine (the current Morrow Audio Map3 on the amp and the Audioquest Thunder that ended up on my PS Audio Power Plant 3).

So anyways, back to the main question, I would like to hear if it's a big enough improvement to get the Triode Wire Labs over the NRG. 

I own the TWL 7 Plus, 10 Plus and digital power cable but unfortunately, I have nothing to compare it to. The quality of these cables does seem very good though.

Yeah both cables have been getting high marks, I just wonder how big of a difference they'll be. 

Plug directly into the wall and compare to evaluate your current power cable.  I have seen some pretty bad Morrow audio power cables.  your 300b needs a good ready current supply for dynamics.    A cheap generic 10 awg cable will probably get you much better dynamic performance than the Morrow.  I applaud you for trying to say good things about it.
