I can reduce the attn to -6 or -3 or 0 .. but then I would risk hitting a digital ceiling and have digital clipping ..
There is really no degradation / drawback doing it the way you describe. It means that the digital stream seen by the Devialet is -10dBFS which mean that you can crank up de volume of the Devialet up to +10 without running any risk of compression.
The only loss is 10dB on the SNR, so 86dB instead of 96 if you are feeding the Devialet using 16 bits after your processing or 134dB instead of 144 if you are using 24 bits. Even in the 16 bits case, I highly doubt that it would be discernible under normal listening conditions and would anyway much preferable than having digital clipping.
