There were several confounding factors :Great great setup!
Can you tell us how the DS Audio Cart compares to Atlas Lambda and Etsuro Gold?
The Master One was installed on the SAT.
The Koetsu/Atlas SL Lambda/Etsuro Gold were on Phantom Elite.
Phonoamps were diff too. These latter three paired with ARC Phono Ref whereas Master One was with the DreamMaster phono equalizer.
Even so, we audio vaterans could still understand their diff with not much difficulty, particularly because Thomas and I auditioned a similar comparison between Etsuro Gold vs DreamMaster on another home system.
Amongst conventional cartridges, Etsuro Gold is the overall champion IMHO. Atlas SL Lambda is very allrounded but Etsuro Gold got the extra magic.
On that other home system, the DreamMaster combo bettered Etsuro Gold, particularly in terms of bass quality and authority.
However the latter was paired with a FM222 phono and without SUT. I think the gain of 222 is suboptimal for the low output of Etsuro Gold.
I am looking for another comparison with more suitable phonoamp/SUT.
