It was a great design in its day. I had one, I bought it used when i was 16. It was my first preamp and not a bad introduction to separates. Then I replaced it with a P.S. Audio 6.2 preamp which was a great preamp, and the first component I regretted selling. I replaced it with a McIntosh C15 which was good , but I think I liked that PS better. Don't get me wrong, the Apt was good but finding a nice one can be tough, and people ask too much for them in my opinion. In hindsight I wish I still had the Holman because it is unique and super flexible. I had the Apt 1 amp which I thought was pretty good also. Another piece I wish I had kept.
Ironically the Apt had a very good phono stage, fairly adjustable.... so if you were looking for a classic pre with a good phono it might not be a bad choice.
