If im going to be primarily using the 64 audio A18s with LID - ("Low Impedance" technology) should I expect any hiss with the M11? Also, anyone have an opinion on whether I should consider the M11 Pro or M15 if only using custom iems?

I was intrigued by the mother of pearl faceplate with the gold logo, simular to how the company website showcases them. Being that my last reference was the JH-13 before the freqphase was released, these A18S will sure be a step up!

Placed my order for the A18s. Sent the impressions, so with rush processing it should be about 3 weeks give or take. Only time will tell. Im excited for them though! Looking to have an end-all CIEM purchase for at least another half decade or so.
