Not sure when which photo you are referring to but at the moment in my office I have an empty bottle of Johnnie Walker Double Black (not bad) and a few drops of Oban left in the bottle. Believe it or not, when I went for my last physical (age 53) my doctor told be to drink more scotch. It does wonders for me so he said drink more.
BTW - I sold my HPA4 last week and I am now using a Topping pre90 preamp. It sounds like the HPA4 minus the great headphone amp and the volume dial on the HPA4 is nicer. However, the Topping pre90 cost $599 and actually seems to measure better than the HPA4.
The HPA4/Topping pre90 are my second preamps so I decided to recoup my cash and get the Topping pre90. My main preamp is the CODA 07x.
