Gurus,
How would you describe the sonic character of the 5687. I am planning to build a linestage preamp based on Knodo's M7 circuit.
I am only familiar with the sound of a 12au7 of a Foreplay on my ST-70.
I understand this is all system & circuit design dependent but any comparisons con the "general sound character" would be appreciated.
TIA
