Yes, you can use the Pre90 to add up to 16dB with XLR in/out.I would like to know if using this pre 90 of the topping I would be able to have more gain....................................
This will permit you to play your present speakers louder (within the limits of your power amp). what it does with other speakers will depend on their sensitivity...........................to be able to drive even more powerful speakers than those I currently have.
What is the input sensitivity of your amp and your present speakers?
