Using this scheme, the signal to noise ratio can be improved as you will see in measurements later.įor speaker terminals there are two sets: classic heavy duty banana jacks and SpeakOn.

At the other extreme, the low gain setting is designed for professional pre-amps with lots of output, getting its max power at 9.8 volts.

A gain switch allows the input level to be controlled so that you can just use an RCA to XLR adapter and still get full power (2 volt max in high gain). Only input is XLR balanced which is just fine in my book. This is a very minimalistic approach given the small amount of real estate available. It is pretty amazing that the AHB2 actually provides 4x the output when bridged that is the theoretical ideal, but most amps spec about 2x the power in bridged mode, probably due to thermal limits. Most of the time that is no big deal since peaks tend to be short. They will current- or thermal-limit without providing full output. Most amps will not oscillate and self-destruct (at least not most decent ones). If it goes unstable into low-Z reactive loads then you should not use it. Most amplifiers can handle much lower load than spec'd it comes down to what the limiting factor is. Finally, the Salon2's are spec'd as 6 ohms nominal with a minimum of 3.7 ohms at 90 Hz so I think I'll be OK. ' They actually provide some specs for 4 ohms in bridged mode, e.g. And they say elsewhere ' The AHB2 is stable into all loads. That does not mean it is rated to deliver full power, though it probably does, but it is stable. ' which implies 2.8 ohms in bridged operation. They say 'Stereo loads as low as 1.4 Ohms can be cleanly driven to full output levels. A couple asked Benchmark and they said it was OK, or so they told me (I have not asked Benchmark myself I certainly will before any purchase). And people do not seem to be having problems in use there are numerous accounts on various audio fora. Yes, I know that, but that is nominal spec and nominal impedance. I'd buy them again but having no doubt in the amplifier is really what you're getting at this level. They're great but the sound quality does not live up to the aura around SOTA products such as this. I say this as a happy owner of Hypex NC400 amplifiers who still remembers connecting them. The low noise floor is great for those with 110dB sensitive horns though. The AHB2 takes it the next order down to 0.0001% (-120dB) which is an impressive feat but drifts from the realities of audio quality.

Even some of the most excellent loudspeaker drivers have distortion components around 0.01%. Most would argue it's even inaudible for music. It's already supremely difficult to tell the difference between amplifiers that are in the 0.01% (-80dB) and 0.001% (-100dB) ballpark in tests designed to reveal distortion. I worry that people will read this and think that this level of performance translates to improved sound quality over the next ~5 measured amps on the SINAD bar chart. It's great to see these results confirm what Stereophile found in their review at.
