AP EVO RS / RSR
Lv 4/4.5
RS
The RS builds on further serious way. It will be based on our copper chassis with our unique Nordic German Gold finish / although the circuit is based on the FFX, but the RS sound tuning combines with the copper sound will provided a more euphonic tone. Complete Cardas Rhodium RCA Connectors, and a extra Hashimoto proprietary small choke will be optional (there is already a small choke inside the chassis).
RSR
The RSR adds one more Western Electric 396a (Total of 2) for better gain/control required by some difficult speakers. It will be one driving another one so the user does not need to buy a matched pair of 396a, which is became very challenging to find a matched pair.
