I'll assume that you upgraded the Mains fuse with the Synergistic fuse ,
may I suggest that you replace the other 10 fuses with
Bussman or Littlefuse ceramic fuses ( $2.00 @ ) .
When working on my DNA-250 I replaced all the glass fuses with
the Bussman fuses and noticed an improvement well worth
the $22.00 . I purchased a Furutech fuse for the Mains
( 1/2 priced at $35.00 ) and compaired it to the Bussman ,
yes the Furutech sounded better
BUT not that much better than a $2.00 Bussman .
