This is not your typical hi-fi sized amplifier. The AHB2 is housed in a compact enclosure that measures only two times a DAC2 (11" W x 9"D to back of connector x 3 7/8"H).
#Benchmark ahb2 amplifier review professional#
It features a bipolar-output power section, 180 WPC output RMS, (350W bridged mono), balanced XLR input, three-way input sensitivity switch and dual speaker input options: binding posts and Speakon, a professional termination that uses a twist-on connecter. However, if you’re planning to use spades (like I am), it starts to get a little tight with the XLR connections.The $2,995 AHB2 stereo amplifier was designed in conjunction with THX. Benchmark recommends using the NL4 jacks. Now, the size does have one (unsurprisingly) drawback – the connectors are closer together. It’s also quiet and doesn’t generate any substantial amount of heat. It feels so good to have so much power in such a small package. I love how I could fit it on my desktop under my monitor. I have to say, aside from how powerful this amplifier is. Snake River Audio Cottonmouth Signature power cord.Depending on your preamp, make sure to set it to the proper sensitivity setting.If you only have unbalanced connections from your preamp, Benchmark has an optional adapter you could use. A balanced connection is highly recommended.You could disable this by holding the power button for 7 seconds (while the unit is on). 2 OUT NL4 jack is only for channel 2 (right). If you’re using a NL2 plug, you’ll get access only to channel 1 (left). You would also be able to use this output in for a biamp configuration. 1&2 OUT NL4 Jack provides access to channels 1 and 2.Supposedly outperforms most speaker binding posts. Three sensitivity settings: 2, 4, and 9.8 Vrms.Two modes: Stereo and Bridged Mono (4 times the power into 8-ohms, 380 watts per channel).Virtually eliminates all traces of distortion at all signal level and loading conditions. THX-patented feed-forward error correction system.Approximately equivalent to the noise performance of a perfect 22-bit digital system. 190 wpc 4 ohms, over 500 Watts in bridged mono.100 wpc 8 ohms, 380 Watts in bridged mono.I am still stunned when I think about the coincidence of these two events. Less than an hour later we got a phone call with the sad and shocking news that Allen had passed away. I announced the name to my staff, and we placed the order for the printing. Instantly it was clear to me that the new amplifier should be named after the man who inspired it! At that moment, the PA2 became the AHB2. It then struck me that the letters A, H, and B were Allen H. The amplifier delivered c lass-A performance, had class-H tracking rails, and a class-AB output stage. I began thinking about the technology in the amplifier and how this could be incorporated into the name. The faceplates were machined and finished but needed to be printed with the product name. On September 27, 2013, everything was ready, but we still didn’t have a name for the new amplifier. In November of 2012 we set the final specifications and code-named the project the “PA2” (Benchmark’s second power amplifier – Power Amp #2, or PA2). Introduced in 2014, the Benchmark AHB2 power amplifier is their second amplifier design (hence the “2”). Passionate musicians, audiophiles, and audio professionals are what makes up the team.

Apparently, it also measured very well with the Audio Precision AP555. The AHB2 has already received numerous accolades and awards from all around the industry. And so Benchmark’s oh-so-popular AHB2 power amplifier came to mind. These days I’ve been doing more 2-channel listening. In fact, it made for some of the most memorable headphone listening experiences I’ve had. Regardless of headphone – I found the system’s dynamic strength and clarity extremely engaging. My interest with Benchmark started when I heard their HPA4 headphone amplifiers and their DAC3 at the recent shows.
