The sweet spot
As you ascend the price ladder of any product category—cameras, cars, refrigerators, golf clubs, what have you—you reach what some call the “sweet spot.” This is where performance is at a high level but short of the very best available, and where any additional increments in performance will require spending disproportionately larger sums of money. For those in the market for a tube preamplifier-amplifier combination, the PrimaLuna ProLogue Three and ProLogue Seven hit this sweet spot head-on. With sound quality that gives up little to much more expensive products, the ProLogue Three and Seven are beautifully built, and, like the ProLogue One, reviewed by Art Dudley in the February 2006 issue, they represent outstanding value.
