I guess a LTA preamp would be a good match for a bit warmer A class amp such as CODA? And warmer Hungary Audio preamp would fit well with Hegel, for example?
I'm not sure what I'm really looking for, but it's OK for me to go in bad direction and replace one preamp with another - this is also a beauty of buying preowned audio equipment - I don't loose a lot of money when reselling...
