“Dr. Cavalli has also included a protection circuit on the Platinum just to help ensure against damage. I accidentally triggered it a couple of times trying to plug in headphones with the volume up and bassy music playing. Oops. Triggering the protection circuit will cause the light on the front to turn red and music will stop playing for about 30 seconds while the amp takes a little siesta.While I wouldn’t go so far as to say, “It’s built like a tank”, it is a solid feeling component and nothing was loose, wonky or made me feel like it was destined to break. The Monolith Liquid Platinum has a good spread of features that make it useful in a lot of situations.But enough of all this build quality stuff! Let’s move on to the fun part… the sound.”

“There’s so much to like here; from the five-year warranty to the way the detents on the volume control feel under your hand. This is a very well realised headphone amplifier/DAC that shows just how professional Burson Audio has become, and the last round showed the company wasn’t exactly goofing around. The Conductor V2+ is beautifully made, can drive practically everything, sounds powerful and full of bass while staying lithe and detailed, and the only real fault I can find is those damn blue volume settings. The original was a real star; this one’s a supernova! ”

“Just when you think the personal listening world cannot come up with anything new, the Manley Absolute Headphone Amplifier brings a mountain of new features and improvements to the party. Not only is the Absolute the most beautiful headphone amp in the room, but it is also chock-full of useful adjustments you really need to achieve the unfailing musicality you crave. With extremely quiet operation, just as quiet as solid state, you will love the satisfaction of owning this masterpiece, regardless of your headphones or musical tastes.”

“I think iFi have a real hit on their hands. The Pro iDSD appeals to many distinct audio constituencies. To owners of an entry-level DAC, the Pro iDSD is a formidable upgrade, both in features and sound quality. To owners of a mid-price DAC, the Pro iDSD combined with a high-quality PSU like the JS-2 would be a compelling upgrade. To tinkerers and tweakers like me, who already have high-quality PSUs and a reference clock, the Pro iDSD provides an extremely economical way to achieve a level of sound quality associated with $5k+ DACs.”

“Bass is detailed, fast, tight and perfectly in balance. Impact and body-wise you don’t get the biggest bass but it’s in no way flat or absent. You get quality over quantity but it will depend on the headphone and even the tubes used. Differently said, the Euforia doesn’t really add any extra bass unless you’re pushing it but it will get the best possible bass to your headphone. Bass layering is very good as well. A clean, yet powerful bass, I certainly appreciate it.

The mids flow perfectly from the bass with the same characteristics body and impact-wise. The mids are always in-line and neutrality here also is a key characteristic. Nothing is being pushed forward or to the back and you get a clean, detailed and spacious sound which is realistic and engaging. The mid dynamics are exemplary and again you get just enough of that tube richness and smoothness to make the amp really shine in this area. The voices also are to dream away with. I read another review where they said the mids weren’t engaging, but if you don’t fond them engaging with the stock tubes, I can only advise to get a better set of tubes, cause they are very engaging with my setup”

“This is the problem the AHB2 is intended to solve with its claimed dynamic range of 135dB—that’s the ratio of the noise (inputs shorted) relative to the full output voltage. A more relevant figure is 0.0003%, the AHB2’s total harmonic distortion plus noise at full power, relative to the maximum output voltage. That corresponds to an SNR of about 110dB. That number should be better bridged, and JA’s measurements show that just below full power, the distortion is lower by at least a factor of 10, so it should be possible to achieve significantly better SNR by listening just below maximum volume. Which means that 120dB is in sight.

Assuming, then, that there are no other noisy components in the signal path—no preamp—the AHB2 delivers to your speakers more of the resolution and dynamic range of the DAC3 (or other high-performing DAC) than will most other amplifiers.”
