"The Truth" from the Hornshoppe. This took me completely by surprise, notwithstanding the rave comments from Arthur Salvatore in the Audio Critique. It's a buffered, active line stage but without gain and uses light diodes to control volume. I have had at least 20 preamps in my system over the last 50 years and I don't think any have matched the transparency and lack of noise that The Truth displays.
