Maxon do some of the finest analog delays ever created. No-one made the proper bucket brigade chips any more, so the overachievers at Maxon just went ham and made the chips in house themselves. This is gorgeous: warm and rich with a great balance of clarity and roundness. I reckon these sound at least as good as a DM-2. Top marks.
