I was able to give my ears a bit of a workout tonight, and it was definitely a learning experience.
My "workout" setup consisted of:
1. Various mp3s (192 kbps up to 320kbps VBR)
2. Winamp (100% volume)
3. Creative X-Fi Xtrememusic (bit-matched playback & 96 kHz up-sampling)
4. Digital Coax output
5. iBasso D1 DAC/headphone amp
6. Sennheiser HD650
For each song, I began with a flat EQ and then enabled Winamp's EQ. I would begin with its preset EQ setting named "Live
" and slowly boost the 12-16k bands until it looked like this
. My intent was to make the adjustments gradually so that I wouldn't notice the changes. This eventual EQ setting is similar to how my home theater sounds with Audyssey off
After I was used to this EQ in Winamp, I would then turn it off, going back to a flat EQ. The song would sound muted (like turning Audyssey on
) - it was as if I had completely forgotten how it sounded before I enabled the "Live" EQ preset and began the gradual shift in the 12-16k range.
The final step for each song would be to once again enable the EQ to the "Live"-modified EQ. Wow, talk about harsh. It was similar to FM radio on a small stereo. To think that I was originally able to creep up to this setting and grow accustomed to it was beyond belief.
So, where am I going with all of this? I'm more confident that Audyssey is performing as it should, and that my setup is naturally inclined to boost the midrange and extreme highs, while sounding a little anemic in the low-end. If you are able, I would recommend performing a similar test to see if you notice similar results.[my HT consists of the Onkyo TX-SR607, Athena Point 5 MK IIs, and SVS 20-39PCi]
