tomp,
Thanks!

Once #2 is modified, will make some frequency response measurements with REW and dspNexus 2x8 to see what needs to be done to get a good response from them.

After all that work please do not keep those cheap-ass fuses. Here is a link for some nice sand-filled fuses that enable the best possible sound quality.
