【Excellent Condition!!】DMSD 50 Black Insulators The DMSD 50, once hailed as the ultimate insulator, is now discontinued. Many of you have likely been searching for these. 【Instant Purchase OK】 ◆ DMSD 50 Black × Set of 4 ◆ Accessories: None Only the main units are included. ◆ Condition Used for testing once or twice, then stored in a closet. The effect is undeniable, dramatically improving the listening environment when combined with speakers and stands. They are relatively clean, but there are some minor scratches on the top and bottom surfaces. Please check the photos before purchasing. They should still provide comfortable use, but please understand that these are used items. ◆ Shipping Yu-Yu Mercari Delivery ※ May be shipped using recycled packaging materials. 【Instant Purchase OK】 * I am also selling a set of 8 and speakers for the ultimate combination, so please take a look at my profile if you're interested.
