I have a pair of Nady RSM-2's and an Apex 205. They serve their purpose and I like them well enough. I have read in a number of places that upgrades ( probably more accurately called repairs or proper setup) of these mics can bring significant benefit.
Has anyone had their mics modded by Michael Joly or similar tech? I have read up on what they do and could "probably" do the work but with no experience and no desire to sacrifice them for the purpose of education I am leaning towards letting a pro do the work assuming of course its worth it.
The very first thing I'd suggest would be to re-ribbon your mics with thinner foil, as it will make much more difference than a transformer swap. The problem is ALL Chinese ribbon mics use 4-6 micron materials, which are much heavier, have restricted sensitivity, and severe resonance modes.
Depending on your sonic preferences you might want to leave the perforated screens on, and ask for an additional damping screen.
A new high quality transformer would be a nice final touch. Since it seems it is OK to plug in the products here, I have my own, Made in USA line of high end torroidal ribbon transformers. They are low loss, low distortion, and extremely low DCR, which results in low noise.
Unlike generic " fit it all" types, they are customized to ANY particular ribbon with impedance, inductance, damping, turn ratio, and frequency response.
