I have not heard of any gallium nitride offerings, but I am hesitant because many Class-D amplifiers are from small companies or one-man shops with no guaranteed succession plan. I would cue up a favorite track with anticipation and be let down every time. They would do everything right except make music. I was consistently amazed that amplifiers that were so dynamic, clean, and detailed could be so uninvolving. There was always some intangible element lost that failed to make them truly engaging. I have heard, recently but not the most recent, Class-D amplifiers. I had considered some highly rated Class A/B amplifiers, but price points and heavy weights left me disappointed. Power without control is like a 60’s muscle car that can’t hang the corners. But Sound Labs can present a challenging load. It was exactly past experience with these conditions that sent me in search of a powerful but cool-running amplifier for my Sound Lab 545PX loudspeakers (reviewed here ). Many record-breaking days followed later in the summer. Most of the country was under a record-setting heatwave with desperate pleas to conserve energy and protect the power grid. My AC was struggling to maintain with little pretense of gaining. It was the first day of summer with a predicted temperature of 104F and many hotter days to follow. It wasn’t a dark and stormy night when I sat down to start writing this review. Obligatory pics of my system with the lucky transducer.Benchmark Media Systems AHB2 Amplifiers by Don Shaulis

I've been using it with Freya (tubes pulled) in strictly passive mode and have a system that can be used for hours without adding any heat to the room, which is huge since it's still in the 100's in Arizona.įeel free to add your impressions and ask any questions you might have for owners of this excellent power amplifier. I thought Jot had excellent bass response with HE-6 but AHB-2 gives it a little extra weight, yet has all the air and clarity you would expect.īest part about the AHB-2 is that it doesn't even get warm, like, at all. HE-6 though, is definitely more muscular out of the AHB-2. With the dynamics it isn't as warm and smooth, as it's meant to be as transparent as possible. It has possibly better width but slightly less depth than ZD. I recently compared it to my Zana Deux using HD800 and HD650, which I feel present stage width and depth more accurately than planars and the AHB-2 doesn't give up much of anything in terms of staging. I've spent a lot of time with the AHB-2, almost 6 hours every day for the last week and a half.
29 A peak, per channel, both channels driven.190 Watts per channel into 4 Ohms, both channels driven.100 Watts per channel into 8 Ohms, both channels driven.I wanted to create a thread for this wonderful power amp from Benchmark.
