Mkilpi, I might say CD8 was not fully burned-in so that the frequency extremes might get even better, but I can clearly say the bass definition of CD8 is superior. It is faster and a bit more neutral in texture so that CD7 is trying to catch the timing and a bit lacks and feels like a bit heavy and boomy. I never felt CD7 had a lack of midbass weight, and indeed it was the player which had more weight and emphasis on midbass. While CD7 was louder and heavier in midbass, CD8 had a better control, faster and deeper (and probably lower) bass definition. So compared to CD8, CD7 sounded darker. On the other hand, CD8 did not have a tonal preference. The CD7 unit we tested did not have upgraded power supply kit. So, I cant comment on whether the new power supply or new DAC of CD8 or both of them creating the difference. Given Wsill's comments for power supply upgrade of CD7, I assume an upgraded CD7 performs better than original CD7. So, a comparison of an upgraded CD7 with CD8 will be more meaningful to evaluate the CD8. Best Regards.
