I hooked the DAK-1 up last night between my phono preamp and receiver. With the knob set at about 11 o'clock, it does a very nice job of reducing the noise floor while not audibly affecting the music. Turning it all the way to 5 o'clock rolls some treble off but whacks even the crackle...might be good for old 78's or a really crackly record, but normally one wouldn't want to set it to such a severe level. Pretty pleased with it thus far...another weapon in the arsenal.
So, this SAE thing...what's the difference between a 5000 and a 5000A?
