I guess that Rall SR1a has tighter bass than Stax 009S.
But I am not sure whether SR1a has refined mid range as latter.
I have not got Stax yet.
Probably I will give Stax and Carbon amp more than one month to tune the sound using different power cable and interconnect.
After fully tuning 009S, I will order SR1a to compare with 009S.
Since I have excellent 2 channel system with powerful bass up to 20hz, refined midrange out of headphone is more important to me.
In the meantime I would like to collect information how to get the best sound of Stax 009S and Rall SR1a .
If I find Rall not to have as refined midrange as Stax, then I may return it in within 14 day's of grace period.
