I don't know the seller, but I thought I would point out a couple of things that I know from checking out the Harbeth line recently after hearing them a couple of weeks ago at Capital Audiofest:
These are 35th Anniversary Editions with upgraded oxygen free copper (OFC) internal wiring. The Tiger Ebony veneer is a premium finish from Harbeth. Those stands are made in America (Manchester, NH) specifically for the 30.1 and are a very solid and hefty support that places the tweeter at ear level where it should be (saw the same stands at the show).
The Red Wine Audio rooms with the 30.1s have been getting very positive comments this year at a few shows.
Good luck with the sale!
