Best Sounding Passive Preamp
What is the best sounding inexpensive passive preamp? I may have to send my preamp in for repair which could take a while and I don't want to be without music. My top priority is sound, but I don't want to spent a lot of money as I will be putting my preamp back in system upon return. Help please.
