This weekend I located a set of the Chinese style mag lev footers, and placed them under the pre-amp. The Trinov has a sophisticated DSP program, and one function it has is a very precise EQ option. I decided to experiment with it. I did in depth reading from websites dedicated to studio/sound engineering work to get an understanding of what I wanted to achieve.
I started with a 1.1 dB cut from 1K to 5K. I then added a 1dB boost from 200 to 400 Hz. As I understand it you should cut first and boost as a last resort. But I am a newbie, and in this case it worked for me.
I then started listening to several reference discs and began to reduce my settings. The sound was a bit too smooth and a touch too warm or vague. I can reduce by .2 dB. My first cut was from 1 to 5K and I went to -.6dB from -1.1 dB. Then I started cutting by -.2 increments. I also worked in the 200 to 400 hz range with the -.2 dB amounts.
My final settings are
+.4 at 200 Hz
+.4 at 250 Hz
+.6 at 315 Hz
+1.0 at 500 Hz
-.4 at 1KHz to 4Khz
I zeroed out the 5KHz setting, so no correction there.
My objective was to get to the point where the sound became harder and forward, and back off one click and see what I thought. I am listening to these settings now and appreciate the clarity and detail and have not heard any aggressive tendencies.
So far this is an enjoyable presentation. What I find fascinating is that a .2dB change in equalization is clearly audible. 1dB is significant, and to think how easy it is to influence the sound should give a person pause when selecting associated equipment, cabling, room placement, and what goes on the walls. This hobby is amazing, and it fascinates me how the little details matter.
