We played around with both bridged and not for the ADA1500 mono-block. In the end we decided on no bridging. All the numerous advantages to a mono-block design exist in both arrangements so it came down to which way would the use of the full dynamic power of the single power supply best be utilized. Bridging greatly increases the continuous power by halving the impedance seen at the amp but it does not change the available dynamic power. Since the continuous power of an ADA1500 is already way above the what would ever be required we decided the stability of the of the overall system would be better by not bridging.
