Which component is most responsible?

The best recorded choral CD I've heard is BIS CD-533 "Christmas Music" featuring the a capella male chorus Orphei
Dranger of Upsulla University.
Its not all Christmas music and its not all in Swedish,but is all magnificent. Three male voices alone singing the "Coventry Carol' made my hair stand on end.

Straight up gang, the Swedish Choirs are the worlds best and the BIS label makes the best Recordings extant.

3 male voices is a simple task for decent system... 100 + voices with multiple counter harmonies is not. Carmina Burana is a piece my system struggles with for air and definition in massed chorus passages regardless of LP or digital.

Johnnyb53, nicely put. In another thread I mentioned just how much my sound improved by using smaller vent slats on my Tonian Labs TL-D1s. They are a semi-open baffle design and are never completely sealed. They vent to the rear and when going to the smallest vent (allowing the largest opening) the images lost that projection artifact and almost seem to float and radiate sound in more directions. A most pleasant improvement. Along with that, there's more detail retrieval which adds to more realism.

All the best,
Nonoise

+1 like to JMC. When should we finally get these buttons? There's plenty of existing code so little to no effort required...

Davide 256, I think we all know that. The 3 voices are 1 track of 16.Carmina Burana is miked for what it is, an exercise in vulgarity.
But then I am at fault for not mentioning that the Choir of a major European University, with a student body of 40K, where Choirs occupy the position of sports at a US Uni , has more than 3 members.
