"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. Their first commercial product, the Dac1, was very well received worldwide."
"Of course it didn't stop with d/a converters. 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."
"These devices are indestructible, wonderfully compact and not very heavy."
"Their greatest quality, however, is their versatility. With the HPA4 you can adjust the balance, name each input, set each input separately (useful when testing DACs) and control the volume very precisely."
"The AHB2 is also particularly versatile for a power amplifier. For example, you can adjust the gain (useful when testing DACs with volume control), a SpeakOn connection is possible and you can convert them into a monoblock."
The AHB2 rear panel features XLR inputs, SpeakOn outputs, a 3-position gain switch and a Stereo/Mono switch.
"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 AHB2 is not cheap, but it does deliver great quality. It is particularly versatile, compact and indestructible. And even more than in stereo, the playback in mono is 'off the charts'."
"There's no going back really. You have been warned!"
- Geoffrey Vanhouwaert, Alpha-Audio
"Merriam-Webster defines a benchmark as "something that serves as a standard by which others may be measured or judged." This is what the AHB2s has become for me."
"A pair of AHB2s are now part of my dedicated summertime amplification for my Sound Lab 545PX loudspeakers."
- Don Shaulis, The Stereo Times
"I was led to Benchmark Media Systems through recommendations from Roger West, the designer of Sound Lab speakers. Praise from a local Sound Lab dealer and a local Sound Lab owner effectively twisted my arm to the point where I yielded to temptation to try the amplifiers ..."
"The Class-H Benchmarks give me what I wanted from Class-D amplifiers, but with the musical engagement, I found lacking in Class-D. There is the added benefit of a company that has been in business for over 36 years and has a depth of products, and offers an extended warranty."
"The highest compliment I can pay a piece of audio equipment is that it has found a home in my system. A pair of AHB2s are now part of my dedicated summertime amplification for my Sound Lab 545PX loudspeakers."
"The Benchmark performance continues to engage me, and the company gives me confidence in long-term support."
- Don Shaulis, Stereo Times
"I love, I love, I love my Benchmark AHB2 power amps!"
- Theo Nicolakis, Audioholics Online A/V Magazine
Theo uses a pair of AHB2 power amps in bridged mono (480 W into 6 Ohms) to drive a pair of Revel Ultima Salon2 loudspeakers ($20,000/pair). This is his reference amplifier-speaker combination.
