The T+A is on the warm or neutral side? Is it warmer or more neutral than the Pass combo?
@mrrui
I’ll sidestep your question, somewhat... : )
Warmth and neutrality are subjectively defined and experienced at an individual level. Not knowing where you fall, and whether we have overlap in the spectrum...a direct answer only applies to me. If you were to push me on it, I’d say the T+A is both warm enough and neutral enough... which some (many) would label as contradictory.
Now, my focus in comparisons is on realism and naturalism. Both, of course, are also individually defined and experienced (as above) but they are higher level / holistic criteria (for me). I’m looking for a summation and synthesis, not reduction.
The T+A delivered a more realistic and natural presentation, and as a result provided me with greater engagement and emotion than my Pass amp. The Pass amp sounded "hazy" and "grey" and "slower" in direct and relative comparison. In other words, the T+A provided a clearer and more transparent soundscape. Some would say it "gets out of the way" more effectively. T+A’s high current design / approach also allows for greater control of the music, yet with a very nuanced and light touch. To summarize, the T+A sounded more "correct and right" in comparison to my Pass amp, within my then system.
I’ll also mention an issue that’s become much more central to how I evaluate / think about components. In this case, I believe it best to consider the amplifier > speaker cable > speaker as one and a fundamental section of the system [in which the entire system+room is the ’component’ being evaluated]. Therefore, how each amp behaves with the speaker cable and speakers you are using may result in different outcomes and ultimately your preference.
