Hi to check the THD i am using LTSpice and the models available on the basic configuration I am still struggling with adding models ... i am a little retardedCan I replace BC556 with BC560 as drop in?
Can I replace 2SC5876 with a general purpose type as drop in?
How much impact from these changes for stability and performance wise?
Anyway i am attaching the original buffer present in the old vintage Kenwood 700c
My curiosity was originated by the very positive opinions on its line stage sound ... very clean and detailed
My principle is that an amp chain that sounds good must be formed by stages that sound good by itself
I am usually look at those stages following the volume pot and called flat amp or buffer amp or output amp to understand a little about the schematic
However i have been convinced that when really great performance are the goal nothing but better opamps
I see some very high end manufacturers switching from discrete circuitations to opamps these days
And i am talking about price of 140 kUSD

You could make a very low noise power supply... About noise I am not sure if simulation results are valid, so it needs a small test...
If you mean the self noise of the circuit should be minimal
I do not have a clue about its PSRR but it could be decent
