Toppings Amplifiers T'ang-ku-la module vs NFCA Discrete module vs NFCA op amp modules. . Is the upgrade even worth discussing ?

[Earwax]

Researching the above modules and NFCA op amp design so far it appears the only notable upgrade worth mentioning in the T'ang-ku-la module is that it minimizes heat generation but by how much when compared to the NFCA Discrete and NFSC op amp design ?

It appears Topping has not provided public data on the NFCA module's thermal performance under specific load conditions, nor has it published controlled comparisons against the T'ang-ku-la module. Therefore, there is no definitive way to quantify exactly how much less heat the T'ang-ku-la module produces.

Other than that the spec`s appear to be to an even match or so infinitesimal it`s not even mentioning as far as ear drum to brain equations ...

Or is there something I have missed other than heat generation, that also is proving to be difficult to find factual information to do comparisons.

I`m under the impression so far the NFCA op amp design operates at a much higher heat probably why the massive heat sinks are implemented.

The NFCS discrete modules have no heat sinks nether do the T'ang-ku-la modules.

The A70 pro has the T'ang-ku-la module as also does the B100 amps I have both in my setup.

The B100`s when driving speakers are warm to the touch but the A70 stays cool just as cool as the D50 III Dac so the heat generation question appears to be related to how many amps ( Electrons ) are passing through them ?

Worthy to state I`ve only been using the A70 Pro in PRE AMP mode so far so the cool running's I`m experiencing might differ when using headphones. I have 300 ohm headphones ( Sennheiser HD600 ) I`ll drive those a bit hard for an hour and post up the temp of the A70 pro comparisons.

On a side note the Topping L30 II when using ether pre amp or HPA mode is always warm to the touch never hot but on the higher side of warm.

Just to be clear so we are on the same page voltage is just a measurement of potential for energy to move from one end to the other ( voltage is the measure of the difference in electric potential between two points ) the higher the voltage the smoother the journey of amps.

Personally I have no idea what the perfect ratio is for use in high end Audio, If it`s easier for you to comprehend watts instead of amps than there it is so lets leave that alone people reading this are not stupid as some would imply while others are of great service to our civilization
