Can Coil Audio CA-70 handle ribbon mic?

I have a Coil Audio CA-70 that I love to use for my vocals and was thinking about getting a ribbon microphone to use with it...specifically a Coles 4038.

Is there enough gain available in the Coil for using a 4038 on sources like acoustic guitar or vocals?

And will the Coles get along with the impedance o.k. from the Coil?

Thanks!

Probably, however, I used another great preamp and fed that signal to the Coil line level input. I can't test now as I sold my 4038, did not like the lack of a shock mount. BTW, sold off all my great ribbons except Beyer 160s which definitely benefit from Pueblo preamp impedance.

If you don't have another preamp (high quality and transparent) to feed the Coil line-level input, a relatively inexpensive option worth exploring is a Soyuz Launcher in front of the 70.

Or get the active, phantom powered Royer R-122 - 13dB more output

The CA70 is a low to mid gain micpreamp so it may be workable with a low ouput ribbon if you are dealing with fairly loud and close mics sources and you crank it. I haven't used a CA70 but as it's a fairly pricy high end preamp I would imagine you can probably use practically all of it's gain and have it sound good unlike cheap low gain preamps that get hissy as you exceed 4 o'clock or so on the knob.

Do you have a compressor or limiter?

If you run your preamp to a compressor many will work well as a line amp and get you another 10 or 20db of nice gain which would get you into a good range.

Yes, the chain would be the Coles into the Coil (unless I take one of the suggestions above and supplement the gain before going into the Coil), then into a Retro Sta Level, then to Daw.

I'm also considering inserting an EQ in that chain as well to lift the highs a bit going to DAW. That could be another gain supplement.

Thanks everyone!

That Sta-Level might be perfect given the gain, (Total System Gain: 35dB (with standard input and output pads), noise becomes the variable.

Here for the gear
 

A long time GS lurker chiming in here.......
Thats the exact set up I've been using lately.... 4038 > CA70 > Retro Sta or 1176. Plenty of gain but if not I'll stick in a Cloudlifter Z powerd by a Radial phantom box before the Coil.
