hi
which one has good bass reproduction ltp or fully symmetrical amplifier? kindly share your experience. 😀😀😀

Your question doesn't make much sense without your schematics as a pair of transistors work from DC to their upper limit, normally many MHz.
A fully symmetric amplifier front end is just two fully opposed LTP's , like in a typical "leach" amp. So both have LTP's natively.
Current feedback symmetrical amps have something similar to a LTP , but feedback is implemented through each transistor individually.
Beyond subjective , I have noticed that my "spooky" symmetrical leach type amp had better bass control while listening to my 20K FLAC collection while an LTP "blameless" was more defined in the high freq. content. Many who built the original Leach amp also noted the refinement (character) of the bass in this design.
Since I had the ability to directly swap the two front ends out in minutes , my A/B comparisons have merit. Output stage was the same for both ...

i experience the same thing i have elektor amplifier from input to output fully symmetrical bass has special character more defined and punchy . vocal and high frequency is not comparable with my P3A where my P3A wins in vocal and high frequency band.

Unexpectedly, I found that my Singleton input amp wipes the floor with any of my ltp or symmetrical amps when it comes to bass slam and treble purity but I don’t think that this bit of the amp by itself determines the quality of the sound. As said already, you gotta look at the whole amp.

Implementation matters more than topology.

EMF (flyback current) interaction with the OPS is another factor. EF3 like in the leach are natively ideal for driving huge voice coils suspended between huge magnets 🙂.
