I dont doubt that the Sansui EQ is very good...
I always used a Sansui alpha for my headphone, especially after i tried one year ago one of the top tube headphone amplifier to replace it... ( i will not name it because it is a good headphone amp no doubt,if not i would have not order it, but not for my K340 picky needs, no headphone amplifier can drive the K340 ideally )
It takes me 15 minutes to return it back so much the difference was huge on all count (save the noise floor level way better with this upgrade costly linear power supply which go with it even if the Sansui noise floor is good it is not pure black but all other factors were completely absent, holography, timbre naturalness, out of the head soundfield, physical tactile bass etc )
The Douk T8 pro is peanuts cost and do not introduce noise... ( audible from my system)
I will not use the Douk in a costly system... But i can recommend it for anyone who cannot put a 2,000 bucks equalizer in a few thousand bucks audio system for sure...
I am curious to compare the Douk to any equalizer under 500 bucks...
I know another who speaks highly of onboard Sansui EQ in pre. The Douk T8 Pro7. Looks cool. I wonder for sh-ts and giggles how it’d conmpare sonically to CO. Temptyto find out. Cheap on Amazon.
