I have an Objectivists system with a Topping pre90, Topping D90SE DAC, and Benchmark AHB2. An ASR SINAD wet dream system. Though I got the system together from reading the much more reliable reviews from Sandu on Soundnews.net. The Benchmark LA4 preamp was once used in this system but now needed elsewhere.
I also have a Subjectivists (to me) system with the new KRELL / CODA amps and a CODA 07x preamp. I think it measures pretty good but it is more tube like than neutral.
Both systems are great and offer a nice change of pace.
