I owned an ARC SP-9 for a few years and one thing that did warm it up some was the use of brass tube anchors from Mapleshade. I also tried some NOS tubes that I felt made a difference. The ARC unit is a very musical preamp and is worth the extra effort in my oppinion.
Minimax or Audio Research SP 9 mk III ?
Budget is $600 for tube preamp. Looking to add some body and dynamics to the music.
Recently downsized from MWI 9.0 SE Signature and MWI 9100es.
System is Sony PSP 1, Red Wine 30.2 integrated and Vandersteen 2ce Signatures with Clear Day Silver Biwire speaker cables.
thanks
Ken
