Anyways do not want to go down this subjective route and stay on track, the AHB2 is for me the sweet spot, looks wise and performance wise. Especially great for classical music too. I have two systems, both I love equally for what they do for me, but when I want to experience the best 2ch music possible, I go to my AHB2/Cornwall combo, the imaging makes it sound like the musician's are in the room with me, and I can listen for hours. Just crank it up a little more than normal, and give it a couple days and when you start to realize all the dynamics are there and the background is a black hole, the detail starts to pop out at you, and the dimensional imaging is incredible. It would not surprise me if someone does not immediately like the AHB2, it is next level but out brains are use to what we are use to and so it may sound bad to someone at first. I forget, but basically it is the cleanest, distortion free, noise free signal you can feed a pair of speakers with. I meant instead the 33 and 33H.ĭon't quote me here but I believe something about zero 2nd and 3rd? harmonic distortion. I wrote earlier that the ML 32 and 32H had regulated power supplies. Crossover distortion is almost non existent and bridged it performs like a 500 watt class A amp into 4 ohms. Bandwidth is competitive with a Spectral amp, without any of the instabilities. There is even a reviewer that uses them as headphone amps, that’s how quiet they are. Note only the power supply is switching, the amp itself is not, so as Amir explained, they have enough bandwidth to be an AM radio transmitter. If they are ever driven beyond safe operation, they shut down. I suggest you read Amir’s review of the AHB2. The Benchmarks just never clip into them. The Constellations Centaur mono that I switched to AHB2s also had a high class A bias and my speakers are 4 ohm. Don’t be fooled by the physically small size of the power supply in the AHB2 as switching power supplies are much more efficient. The JC1 I’m pretty sure is not regulated and it simply depends on caps to hold the voltage steady. And the switching power supply of the AHB2 is a regulated supply. That is less than 3 db difference vs 800w. The bridged AHB2 can deliver 500+ watts at 4 ohm with vanishingly low distortion. I would suggest that this depends on your power requirements in combination with your speaker efficiency and impedance profiles.Ĭlick to expand.I wrote earlier that the ML 32 and 32H had regulated power supplies. (Same power / speaker impedance / SPL parameters apply of course!) and there are plenty of excellent contenders. If heat/efficiency is an issue, then a Class D design is likely to be more suitable. Others have impedance curves from hell with multiple dips to below 3 ohm, or below 2 ohm - on those, you can hear substantial differences between many amps. Some excellent speakers are relatively undemanding - nice even impedance curve, staying above 6 ohm, SPL/wm of 90db+ The easier the speakers (and room) are to drive ( the less demanding of the amp) - the more alike amps tend to sound. If the AHB2 can achieve that - then the substantially more powerful JC1 or ML536 probably won't sound much different, if at all. and at your listening position, in your room. Click to expand.I would suggest that this depends on your power requirements in combination with your speaker efficiency and impedance profiles.įirst step in choosing an amp, is making sure that it can provide the necessary V to achieve your desired SPL (including at least +15db headroom), into your speaker impedances at all listening frequencies.
