Gustard N18 Pro LHY FMC switches.

I have the LHY SW-8 cascading into the N18, then into the N18 Pro. I had the LHY first and added the two Gustards later. I did notice an improvement when adding the N18's. The noise floor dropped and details became clearer and micro dynamics came through clearer. 

@deep_333 what i mean by cascading is, i input to the LHY from my router, then out to into the N18, then out into the N18 Pro. Then from out of the N18 Pro into my Audralic Ares S1. 

Anyhow, i haven't listened to them separately. So unfortunately i can't answer your question.
