"Benchmark Media Systems Inc from Syracuse, New-York is an American company and has been one of the top pro-audio manufacturers for thirty years. In recent years they have also ventured into the consumer market with considerable success."
"In collaboration with THX came the AHB2 power amplifier and not much later they developed a suitable headphone amplifier and preamplifier, the HPA4 and LA4 respectively."
"The HPA4 and AHB2 have been a fixture in our reference set for several years now."
Testing an AHB2 pair in Monoblock Mode
"In stereo mode we get a nice 100 watts (8 ohms class A/B) but in mono that goes to an impressive 380 watts!"
"We set the small switch on the back of the AHB2s to mono and connect each speaker to an AHB2."
"Is it worth buying a second AHB2?"
"We say a resounding yes."
"The extra power (380 watts!) not only gives you more control over your speakers, but so much more."
"The playback in mono is 'off the charts'."
"There's no going back really. You have been warned!"
