The HIFIMAN RE-800 IEMs are some of the best headphones I’ve ever listened to. They have the laser sharp focus, detail and resolution only a single driver headphone can deliver, but has bass performance that shames many multi driver IEMs.
The Pass Labs XA30.8 is a seemingly “low power” amplifier that one of the most uncompromised, cost no object amplifiers ever made at its power output level. It offers stupendous performance that the 30 WPC specification cannot hope to describe.
The Rotel RC-1590 preamp and RB-1590 power amplifier are at the peak of the price-performance curve for stereo hifi separates. They offer excellent sound quality, loads of features, power to drive almost any loudspeaker in almost any room, all for a (relatively) modest price.
In this review, we take a look at a collection of portable headphone DAC/Amps, compatible with iOS devices: the Apogee One, CEntrance Mini-M8, Oppo HA-2 and V-MODA Vamp Verza. Every one of these products sounds dramatically better than my iPhone 5S by itself.
Class D (i.e., "Switching") amplifiers have been around for quite a while now. What's clear from models produced so far is they all sound different, even when using the same core technology. Like many amplifiers of the type, the NewClear NC1000L uses the Bang and Olufsen ICEPower module. What makes the NC1000L different isn't this module; it's how that module is implemented. NewClear Audio was started by Sean Brady to improve upon the sound of existing switching amplifiers. Sean had heard some very good amps based on ICEPower technology, but thought he could do even better. The question is, does the NC1000L deliver the goods compared to similarly priced, traditional Class A/B amplifiers?
Schiit Audio is an irreverent company that builds high quality electronics for headphone listeners entirely made in the USA. The Asgard 2 and Bifrost are Schiit's most popular headphone amp and DAC, and they sound and look far more expensive than they are.
