Review: Excellent build quality,excellent sound quality,lovely aesthetics,lovely form!
Review: Looking to spend more than $500 on a combo DAC/pre-amp/headphone amp? This is what you've been looking for, I'm sure of it. It compares favorably against amps costing 3x as much money. My home office includes several pairs of single-ended and balanced headphones, as well as desktop speakers (a pair of JBL LSR305 with LSR310S sub). It dishes out effortless class A headphone power to even the most thirsty headphones, dynamic and planar; even my T50RP Mk2 can be happily powered, given how clean the audio is even towards to the top of the available power. The noise floor is eerily low, and convinced me that my wishy washy feelings about the LSR305s were more a result of my previous pre-amp than anything wrong with them in particular. This is an exceptional addition to my audio kit, and it's going to push out some previous favorites!

## Features

- The Questyle Audio CMA400i DAC with Headphone Amp exceeds all expectations and includes all the state-of-the-art technology of the Questyle Golden Reference System with a full-balanced Amplification featuring four groups of pure Class A Current Mode amplification circuits.
- CMA400i can drive headphones in full-balanced mode as it features four groups of pure Class A Current Mode amplification circuits, and supports a 4PIN balanced XLR output, a 2.5mm balanced headphone jack and a 6.35mm standard headphone jack. In addition, the new design of Gain Control switch at the bottom of the chassis benefits CMA400i with perfect driving power for different headphones.
- CMA400i has a great capability for signal processing, supporting Windows XP, Vista, 7, 8 & 10, and Mac OS. When connecting to a computer, it is only responsible for sending data. So everything related to sound quality will be guaranteed by CMA400i, no matter if it is a song, a film or a game.
- The performance of a traditional Hi-Fi system can be much improved by CMA400i because of its completely separate DAC with optical and coaxial interfaces. Another distinctive feature of CMA400i is switching between "Headphone Amplifier" and "Pre-amplifier" by the "Function" switch on the front panel. In DAC mode, CMA400i supports RCA and XLR pre-amp outputs which can be selected by the ADJ/FIX switch on the rear panel.
- CMA400i supports pre-amp unbalanced (RCA) and balanced (XLR) outputs. RCA pre-amp output level is up to 4Vrms, and XLR up to 8Vrms, which can meet the requirements of most power amplifiers for output level. Volume control works in analog mode only. It is user-friendly for users of high-end active speakers. CMA400i supports 4PIN balanced output. Four groups of pure Class A current mode amplification circuits drive headphones in full balanced mode, doubling the output voltage, quadrupling the outp

*by C***N on 19 April 2018*

The sound quality exceeds my expectations at this price point. Clear, detailed, flawless. Plenty of power for 300 ohm cans, and the impedance matching for IEMs works great. It cools well, gets warm but never hot like Schiit amps do. The construction is very solid, and the machining tolerances are surprisingly tight. The button to select between headphones and line out, the ability to select line or preamp out, the front-mounted power switch, and the wide array of input and output options make this a versatile and future-proof desktop solution.
