Sorry, but not buying the "sister company" relation, Harman Kardon, Infinity, JBL, Revel and maybe a few other Audio companies is owned by Harman International, it does not mean that JBL, Infinity or Revel would be best paired with a Harman Kardon amplifier, though some models may "match" depending on ones taste, room and subjective qualifications, but throwing a blanket statement that Rotel amps is best paired with B&W speakers is in my opinion is wrong regardless if they were made in the same country or factory. my 2 pounds, este centavos pala
