Re: [LAU] LADSPA Plugins from ALSA,would like some help, please !

Did you compare the result of harmonic whatsoever tools and tube simulations with just using an EQ? If a clean sound shouldn't be required, you maybe should compare a compressor with the faked tube saturation. If an EQ can't produce the wanted clean sound, then simply because either frequencies are missing, e.g. caused by the amp, or they aren't available by the audio source or because the speaker can't produce those frequencies. Adding some magic harmonics can't replace missing frequencies. If a biased sound is ok, IOW you don't use the setup to mix audio productions, you should consider to compare a controllable tool, such as a compressor, with some magic, uncontrollable tube saturation fake.
