birdland odeon-Ag VS Perpetual Tech P1A/P3A/P3

"do you know anything about Benchmark DAC1? how do those two sound different??"

I have not heard the Benchmark DAC. Only got feedback from customers that do shootouts. No comparisons to Birdland, though.

Here is my performance ratings for modded and stock:

Stock:
1) Birdland
2) Bel Canto
3) Perpetual

Modded:
1) Perpetual
2) Birdland
3) Bel Canto

Unless the person responding has heard all three in the same system, like I have, they cant make this determination.
