Reducing the strength helped but it then started to let through too many clicks. I tried the same recording with Audition and felt, that while it sounded a little rougher, it also kept more of the high frequencies. I only had 3 or 4 clicks to remove manually after the Audition process.
I'm going to try a few more side by side comparisons - just to see whether it was that particular track that gave problems - maybe RX doesn't like punk rock!
My 15 year old Steinberg Declicker when pushed would start to add a "furry" distortion to wanted content, so I backed it off until the distortion just disappeared. I also found that in quiet passages I could apply Declicking more heavily without the same onset of distortion.
In my experience when someone claims a tool "sucks the life out of the track" they are usually referring not to a Declicker but a broadband Denoiser (spectral subtraction).
A year or so ago I bought an Acon basics package with Declick, Denoise, Dehum and Declip. The Declick is split into two sections, a Declick and a Decrackle. I found that while the Declick worked well, the Decrackle added watery artifacts, usually associated with a Denoiser. Does the RX6 Declicker possibly contain both Declick and Decrackle? If so, it maybe worth temporarily disabling the Decrackle to see if that is causing the problem.
Interestingly well regarded 78RPM reissue engineers Ward Marston and Mark Obert Thorn freely use Declickers but appear to draw the line at Denoisers, which may also include Decracklers.
