I am testing Apollo and Atlantis Eartha cables.
Starting test with:
a. Silver Tellus through Apollo to Totaldac Reclocker,
b. Olympus Mini through Apollo to Totaldac D1 Dual.
1. replacing Atlantis on Silver Tellus to Totaldac Reclocker, which is a digital buffer and USB converter, so only digital signal, the effect was too black. Some more bass, but lost some harmonics. On some tracks the impact is very satisfactory, increasing the texture of music, the body, but lost some details.
2. replacing Atlantis on Olympus to Totaldac D1 Dual, great effects. More bass, more real feeling maintaining great details and harmonics. third dimension even more improved. Bass articulation is like as the instrument is in front of you. On Autumn Leaves by Patricia Barber, the bass is full-bodied and harmonically real.
Entreq items need to be tested on system to have a picture of the benefits. but the result obtained with a bit of patience is fantastic.
