I've tried various scandoublers (PicassoIV, Amber..) and none of them are as good as C=1084 monitor.
The colors are just not as vibrant. and its the same with LCD or CRT VGA monitors.
Actually, color reproduction is 99% a matter of the monitor. The A2320 (or the A3k) use the exact same Vidiot DAC, so coloring is identical. I even verified that back in the days when I owned a Mitsubishi EUM that could run both 15 and 31 kHz.
Color perception on a 'glare' monitor like the 1084 tends to be crisper, more vibrant. More modern CRTs usually have (or should have) an anti-reflectant surface which does damage the colors a bit. But I wouldn't call the 1084 a 'quality' monitor or 'the best' for that...
An LCD otoh is something completely different. CCFL lighting is fair at best. For a decent colorspace LED backlight is a must - and even then it's somewhat different.
