Harmonic recovery System


Not reall an amp, preamp question, but has anyone used this tweak.
I think its basically an added gain stage. If anyone has used it , please let me know youre impressions. Thanks

Jayctoy,
May I ask which one you like better, the AH4000 w/ upsampler or the Sony 9000ES w/ mod?
