Let me try again A21. Thats pretty funny. I have the Brooklyn DAC. Adding a couple Sub woofers and need both the XLRs for the A21 and the RCAs for the Subs. I have been messing around with some single drivers and I like them so I figured if I get some good subs I can get all kinds of different drivers. Just curious because the A21 is not an actual balanced input is that 6db increase that usually exists between a true XLR to XLR in this case.
