Stanton 681-EEE-IIs. Up for sale is a legendary Stanton cartridge. This was bought NOS, and I think it was. I had it mounted to try out, and it sounds like a new cart. There is plenty of high-frequency information. Tracks brilliantly as one would expect from a stanton cart. All the included paperwork matches the cartridge. The plastic mounting blocks and screws are included and are still in the unopened, original bag. The little metal box and screwdriver are in as new condition. The case is in nice condition, but the clear plastic sleeve has a couple of cracks. Genuine sale, I put less than 30 hours of play on this cart. The reason for sale is I have two, as well as a couple of Pickering equivalents.
