I was listening to my CD3K's tonight through my Supermacro amp. As usual the peaky highs were beginning to bother me on some music. So I decided to flip on the Supermacro's impedance switch. This switch adds 75 ohms of impedance and it is mainly designed to convert the Ety 4P to a 4S. Well naturally I had to increase the volume setting to get the same volume. But I noticed that the sound was slightly warmer and the peaky highs were not so peaky. I flipped the impedance switch on and off several times and repeated the same songs to get an A to B comparison. I only did this comparison over a period of about 20 minutes so I'm not sure of my conclusions. But the addtional 75 ohms did seem to improve things. I also have Xin's 75 ohm adapter that I can use on my other amps to see if it makes the same improvements that I think I hear. Anyone else try this?
CD3000 plus 75ohms improves SQ
