(http://www.tactlab.com/Products/22MINI/index.html) Check out this unit. I am presently using the big brother RCS 2.2X and have been very well pleased by it's lack of any negative audible impact. I've been familiar with the professional digital crossovers and signal processors for years being a sound tech for a number of local venues. The manufacturers have to use less expensive internal components to keep the cost of their units in the $200 to $400 range. They WILL leave a sonic footprint. TacT Audio won a 'Golden Ear Award' from The Absolute Sound in 2007.
Is there better pre-amp for "bi-amp"ing ?
I am using GFP-750 to drive two Levinson 333 + Nautilus 801.
- unbalanced output is driving the first 333 to bass section
- balanced output is driving the second 333 to mid/high sections.
I tried Anthem with similar configuration but the output level between balance and un-balance are off by 6dB so can't do.
I tried Audio Research pre-amp and use Y - connector to drive both 333s. It seems the output driver of the pre-amp is not designed to be loaded with two paralell inputs (two AMPs) so the sound dynamic is lacking.
Has anyone experiment with bi-amp and found improvement over single amp? What pre-amp did you use?
Thanks.
