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 am sure they are nice but I have heard for years that the glass diamond telafunkin tubes are the holy grail if you can find. I found once but $500 per was out of my reach.

TWL cables are tremendous values and Pete's customer service is second to one.  The 7+ cable is dynamic and was voiced on Pete's system which is 300B based.  
 

People all too often think of power cables only in terms of gauge.  The geometry of cabling is at least as important as gauge and materials.  My MPC Mini++ cable (PFO Brutus Award winner) is a 9 gauge cable.  The standard Mac power cable is 18 gauge.  Why?  Because it took that gauge in a double helix configuration to get the inductance extremely low and the capacitance high, which is the impedance mix that the SMPC likes for optimum performance.  

The TWL cables are built using terrific materials, advanced geometries and voiced for different applications.  Best part is that along with the cables you get a business owner that has his customer's satisfaction as his highest priority.  Very seldom does anyone take advantage of the 30-day return policy.  Highly recommended!
