There is no doubt about it for me. The rig in my AV room tops everything else I have heard by a wide margin.
I was at Orchestra Hall Minneapolis on Saturday night for the end of the Beethoven marathon. The last work was Beethoven symphony No5.
When I got here yesterday, I played the BIS 5 channel SACD. There is no sub channel, so I had to throw the switch to go entirely to my bass management. The ambiance comes from the rear speakers, not from the side surrounds, as it should for European mastered SACDs. It is the same orchestra, same conductor and same hall. The only difference being that the hall was empty for the BIS recording.
I played at concert level, and the sound was identical, except that the hall sounded empty with more of an echo. The full MSO in Orchestra Hall with a work like that gets very loud in parts.
Everything on playback here was the same, the typms, basses and cellos perfect along with the upper strings, woodwind and brass section. The trumpets and trombones really blazed. There was no sign of distress, or thermal compression in the rig. It was all just like I heard, except for more reverb from the empty hall. With the excellent BIS recording in 5 channel, it really sounded like being in Orchestra Hall and being a lone member of the audience.
I have not heard any other speakers produce the full wallop of a full symphony orchestra and be totally tonally correct across the entire range.
