Dear Anatoliy,
The "X" means "extented" body. The first production of Colibries were 2.5-3.5 gr and their output was 0.15-0.22mV
One day VDH himself decided to alter the meaning of the "X" and explained as the way the coils are fixed to the cantilever. It is true that soon after the appearing of the first production of Colibrie(s) named as "The Kolibrie", VDH has decide to elevate the weight at 7.5 gr for wider compatibility and to change the rectangular in favor for the cross former upon which the coils are winded. The rectangular former gives more dynamics but the cross shape offers more nuance as it is more sensitive to the imbalances of the cantilever. About the "Low Weight" Vs "XGP" : Among the 7 samples that have passed in my system, my own favorit is the "Low Weight" with Copper coils 0.15mV followed by the "XPP" with Platinum coils 0.22mV. Both of them have had the cross shaped coil winding. I admit my general preferance for the LW body and Copper coils of the lowest output. I think that everything is possible with VDH and you can order whatever you can ever imagine, but I advise you to avoid the Neodymium magnets, the Wood bodies, the Gold coils and especially the output over 0.36mV. Do not worry about the weight and compliance compatibility of your arm (and the dynamic balance is a very rare & welcome feature). This beast is phenomenal and even a little taste of it's performance abilities is enough to put most other top hi-end competitors in the dust.
Congratulations.
