So, Teflon, I do not think you got what I meant.  SET has no 'topological limitation' because exists DSET. DSET is free from any, even theoretical limitation, of cause if you prepared to deal with price and power demands. The DSET optimization for LF operation is well covered in multiple threads if this site. It might depend mildly from the specifics of your amps that you would like to use for LF but the underlining principles are the same across the board.

Ah, I understand what you meant now when you said 'topology', you refer to having a dedicated SET for each frequency band. I did read some of the threads on this site about your amplifier and what I see is dedicated amplifier channels for each frequency band, each one uses same basic topology but with differences at the input for frequency band-pass and uses different output depending on the demand from the load - meaning more power for lower frequency.

I do not remember that Sakuma-san use the DSET concept. The bi-amping that he demonstrated to me did not use DSET, used tow identical amps and in fact was implemented in what I call the “ridicules fashion”.

this link explains what I was referencing. There are three pages, the schematic is on the 3rd page.

What is the weakness you see in this implementation ? - is it because of the use of Push Pull for LF ?
