To clarify, the noise I’m hearing requires that I be within a few inches from the tweeter/woofer to hear. Most of it comes from the BHK and the particular valves I’m running currently.
I didn’t mean to characterize what I hear is ‘noisy’ or negative. My system noise is in no way objectionable or even noticeable by anyone but me. Of course, only my significant other and two dogs have listened to it.
