Dear @chungjh : " I still don’t understand. Wouldn’t decreasing the gain on the Kitsune do the same degradation? "
Certainly you don’t understand the whole issue and why you are connecting the phono stage Kisune to your Allnic L7000 preamp .
Btw, normally and in general sense as lower gain we need to achieve the desired SPL ( volume ) in our system as lower degradation will be developed.
The sound degradation I talked about is generated/developed inside the L7000 preamp due that it’s a a designed preamp coupled through transformers and it’s inside those transformers where the cartridge signal coming from the Kisune " seen " incremented that signal degradation and that’s why I told you that a good " move " could be to change the L7000 for the Pass X22 or X12.
In the other side: "" is there a way to quantify/measure the room deficiency? "" please let me know how you did it your room treatment . Only through your ears?
