BeesNeez m7 Capsule in G7

[banio1208]

Hi
Is that a normal a that BeesNeez m7 Capsule have very poor bass, big boost in mids and 4-8k dip response in Cardio? Feels far away sounding, something like telephone effect, lo-fi alike
But in Omni sounds good, very linear
What you guys think?
Tube is E80F, and Lundahl 1538

No thats not normal. I don't have experience with the G7 circuit though.

What are your polarisation voltages? My understanding is that the m7 capsules can’t always handle the standard 80v of the g7

could it be that you have your capsule wired backwards ?

Around 60V

Backplate not terminated properly? I have my BN M7 polarized at ~63V in an EF-U47 and it sounds fantastic.
