The M5s let me hear all the differences between amplifiers and recordings via its clean treble, open midrange, and controlled, authoritative bass. The M5 was a forensic instrument when needed and an audiophile speaker capable of reproducing rich, true-to-the-source sounds when desired. For not a lot of money. The KLH M5s are intoxication kings, urging me to hear my most beloved vinyl via its big personality and well-scaled dimensionality.
I thought, "If only I'd kept that pair of original M5s I found uptown!" But the revived KLH Model Five turned any regrets into a hearty smile of satisfaction.
