Kevin Hayes is the owner-designer of VAC amps.
I have owned a pair of Phi70 monos since 2005.
Not the most musical amp I have had to date (strange for a 300B) but it does have lots of air and does the space and depth thing right.
In addition to "midrange really uncolored, neutral" you also need to consider "sound-floor". Lookup Arthur Salvatore and read his rantings about this.
