In 3 years of time we auditioned only one system who showed all the parts of Tru-Fi. It had the same kind of structure we use but without Statement Audio Pro-measurement.

Beside the acoustic limitations, creates S.A.P. much more details which are gone with any other highend pre amp.
In a comparison with an Audio Research Ref -5SE the differences could not be bigger.
We used the same Pass Labs Poweramp, AQ Redwood, 2 pairs of AQ Wel Signature xlr and Purist Audio Limited Edition luminist powercables.
The 5509 with S.A.P. had a much deeper and weider stage. The Ref 5Se created 0.5m of stage depth. The 5509 eith SAP can create 5-6metrres of stage depth with the same recording.
The 5509 could reveal details like the articulation of vloices which were fully gone with The AudioReseach.
Even in layers and emotion the 5509 outperformed the 5SE with ease.
The low freq went a lot deeper and had more layers compared to the 5SE.
The individual focus of instruments and voiced was so much shaper and precise than the 5SE. Soon a person with an Absolore pre amp of 30.000 dollar will come to my house. I will ask him if he is prepared for a shootout.
We have proven to many tube owners that our sound shows much more layers and creates more emotion thanb their tube pre amp and poweramp.
We want to use more shootouts in audio. We will make profesional videos of it.
Audio is all about facts and the truth :)
