Or for $200 you could use an UltraCurve for both EQ and time delay on SACD LFE - use one channel inline with the SACD for delay and (optionally) the other inline with the sub output for EQ. Even if you don't trust the A->D->A process for most signals, the LFE stuff should be OK.

Or use 2 of the 100 UltraCurve presets....

Or compensate for digital inputs and engage the relay bypass for SACD....

My first unit should be here any day. The calibrated mic was backordered though.
