mcintosh vs sunfire? in 2-Channel Home Audio Posted November 30, 2007 If you are doing audio only, the BEST preamp I've ever heard, BY FAR, was the Sunfire Classic Tube Control Amplifier (pre). They aren't made any more, but one occasionally pops up for sale, and they usually command about $1,000.00, plus or minus $200.00. They are the cat's @$$! Pair that up with the Sunfire 300~2 channel amp and you are in for a treat!
