I have a pair of USHER BE 10 speakers which are power-hungry, the AHB2 drives them to ear-bleeding levels without any noise or distortion, it's paired with a Parasound P6 DAC/Pre amp and the combination is so revealing I'm finding new sounds in albums I've owned for 40 years, I'm certainly impressed by it and may even invest in a second AHB2 and a DAC/Pre amp as well !
Thank you for the video. I love my amp will be getting the whole stack in the future.
Love my LA4 pre amp
Have reviewed most of your products

klipsch l a scala,, forte,,, too sensitive,,, here we want 60 dba,,, la4 and power amp... can do this,,or no,,, does 7am position already give 90dba,,,
When is the range likely to be updated? It has been over 5 years since the launch of your latest DAC...Competition is offering a far better value than Benchmark outdated DACs
Excellent
pls give risetime specs,,,, will la4 and single power amp produce 90 dba on martin logan esl... these go own to 1 ohm
We often team up with Martin Logan at Audiophile Shows. We like the ESLs because they produce much less distortion than conventional drivers. The AHB2 is a perfect match for the the Martin Logans because the AHB2 distortion is so low that the distortion artifacts will never exceed 0 dB SPL when driving speakers, even when driving difficult loads. The Martin Logans have very low distortion, an this makes them very revealing. If you drive them with a poor amplifier, you will hear it.
As for the peak output level, you can add 20 dB to the 2.83V sensitivity rating of the speaker when running an AHB2 in stereo mode. When running an AHB2 in mono mode, add 23 dB to the sensitivity rating of the speaker. When you do the math, you will find that the Martin Logans will play very loud from a single AHB2.
Here is a link to a calculator on our website that will calculate the peak SPL that you can expect from your speaker/amplifier combination: benchmarkmedia.com/blogs/calculators/simple-spl-calculator
No I2S ports?🤷🏾♂️
how do you bridge ahb2 mono mono ?
Place the switch on the rear panel in mono. Use "1 In/Mono In" for the input. If you're using the Binding Posts then you will use the two red middle binding posts marked "M+ Out and M - Out". If you're using a SpeakOn connector then use the SpeakOn plug marked "Mono Out".
@@BenchmarkMediaSystems hpa4 volume is too low, is there any way I can get more gain? when i use other pre amp for my system the volume is fine. i think the hpa4 is doing automaticaly something to protect thw circuit. when I increase input volume noise rises too. I will be selling this hpa4 if there is no way to increase gain without noise.
@@noob9103 Please send us an e-mail and we can have our tech support help you with this.

The HPA4 and LA4 have more gain available than most preamplifiers. 0 dB on the volume control is unity gain (XLR to XLR or RCA to RCA). The maximum gain is +15 dB. The volume control goes all the way down to -112 dB in 0.5 dB steps. When the volume control says -50 dB this is not 50% it is -50 dB relative to the input signal which is a very low level. The analog circuitry in the LA4 and HPA4 are very low noise and these devices will not produce audible noise. If you are hearing noise when turning the volume control up to +15 dB, this is due to the noise coming from the source device.
They have a great amp , and pre amp , but need a new muscle amp
It’s due
With a flip of a switch, the AHB2 is that muscle amp. The switch is the stereo mono switch on the back of the amplifier. In bridged mono mode, the amplifier delivers almost 4x the power. 390W into 8 Ohms, and 516W into 4 Ohms. The other unique feature of the AHB2 is that THD does not increase when the amplifier is heavily loaded. This characteristic is due to the patented feed-forward error correction system. We have a set of 2.4 Ohm speakers in one of our listening rooms, and the AHB2 drives them cleanly. Any other amplifier would produce greatly elevated levels of THD. The manufacturer of the speakers selected the AHB2 because it was able to drive these cleanly. They have now modified their speakers so that they have a nominal impedance of 4 Ohms. At 4 Ohms, they can be driven by a variety of amplifiers.
Yeah... It's about time to come out with stereo 200 watt amp. Most people prefer not to bridge.
