I suppose it comes down to the quality of your system. I know I tested the unit on my mains for fun one day and it was quite poor. The best way to test this is to insert the BFD between the preamp and amplifier on one channel. This would allow you to listen to a channel without the unit and another with the unit. For myself, the noise floor was so high, I find it hard to believe anyone uses this for anything but the subwoofer channel.

The spec shows a 94dB noise figure with crosstalk of 76dB. Not too good compared to many systems today.

The 1124’s 94 dB S/N spec is an unweighted figure, while most receivers use an A-weighted figure in the 100 dB range. For more of an “apples to apples” comparison you can subtract ~10 dB from an A-weighted figure, which puts the BFD comparable or a little better than the average receiver in the noise floor department (excluding Bryston gear, which has specs far surpassing the average receiver ).

That said, if you were able to audibly hear the noise floor, that suggests the BFD’s stated spec is highly optimistic...
