Although Poland's most famous loudspeaker manufacturer started with budget speakers, its current catalog is dominated by mid- and high-end designs. The top position is occupied by the beautiful Jaspers, available in both passive and active versions. Then we have three series consisting of a single model - Amber, Jade, and Emerald. The bottom four is made up of the Ruby, Sapphire, Opal, and Pearl series. Right in the middle there's a series that has become a real market hit, combining minimalist design, high-quality workmanship, a rich color palette, and natural, balanced, and universal sound. The Diamonds were Pylon's flagships at the time of their launch. I remember how the bosses of the Jarocin-based manufacturer, still unsure of the rightness of their decision, wondered whether such loudspeakers would appeal to customers. Today, the company could probably produce only this series and would easily balance the books (especially considering that Pylon Audio is not only a manufacturer of equipment sold under its own brand but also a supplier of cabinets for leading foreign brands). However, since there was an opportunity to improve them, it was a shame not to take it. This is how the Diamonds mkII were born. To see what's what, I decided to review my favorite model from this series - the "twenty-fives".
