Which Preamp for Quicksilver Mono 100


Hi All,

What preamp to put in between these and an ayre cx-7 to basically control the volume.  I do not want to spend a large amount.  I currently have it hooked into a extra receiver(Rotel) but I am noticing harsh and forward and not as warm.  Anyone can recommend a nice preamp to drive these under $500.  Used is fine.

Sincerely,
Larry
