Grace M101 Microphone Preamp Review

Where did you see that?

It's at -1.9 dB @ 5hz with phantom power enabled.

Unfortunately pretty much all good mics require phantom power.

It's at -1.9 dB @ 5hz with phantom power enabled.

Unfortunately pretty much all good mics require phantom power.

First, the phantom power makes no difference, the blue dotted line is the ribbon mic setting, probably a different input impedance. You think anyone can hear a .5db drop at 20hz? And nobody records 5hz on purpose.

Ribbon mode is probably DC coupled. Normal mode for phantom power needs decoupling caps.
A few db down at 5Hz is no problem - none of the usual mics will give you linear sound down there anyways! You would need a special, omni measurement mic with an extra small vent hole to get down there linear.

Cranborne Audio CAMDEN EC1 does have better specs but i have not found any proper third party tests on it.
