I purchased these jewels in 1991 and they are in superb condition today. They have not been used as much as I would like over that time but they have been cared for greatly. In this last month, I have pulled out my treasured vinyl collection with some disks that are not available anywhere anymore that could be sold for more than $10,000.00 each. My system with the Quests literally brought tears to my eyes with the realism and dynamics that my purchase of Martin Logan was intended for. Family and friends stood in amazement that sound reproduction was this good back in the 90s. Thank you Martin Logan for 30 plus years of incredible sound reproduction investment.
