Bristling with inputs, outputs and switches to manage your desktop audio world, the HeadRoom Desktop Headphone Amplifier delivers amazing fidelity and complete control. Not just a head-amp, the Desktop Amp/DAC is a true analog~digital switching center featuring dual RCA inputs and volume-controlled line output via Cardas RCA connectors. For digital sources, USB [computer], optical or coax S/PDIF digital inputs feed directly into our exclusive digital-to-analog converter (DAC) stage. Includes 1/4" + 1/8" headphone jacks along with renown HeadRoom crossfeed for awesome headphone imaging plus 3-position gain to precisely match any headphone impedance.
The center of your desktop-based listening universe arrives in a curvilinear black-anodized aluminum chassis surrounded by protective molded urethane bezels. The HeadRoom Desktop Amp/DAC presents an integrated solution for all your demanding audiophile headphone listening situations in both digital and analog domains regardless whether it's a headphone-only or a monitor-oriented application. So no matter if you connect to an iPad/ iPhone/ iPod, Windows, Linux or MAC computer, CD/DVD player, pre-amp, turntable phono stage, home theatre/ component stereo system, gamer box, or custom audio front-end, this nook-sized 'Made in Montana' HeadRoom rig driving your favorite reference headphones will transform your personal and near-field headspace into pure sonic nirvana.
The Swiss Army Knife of Headphone Audio Along with analog dual stereo RCA inputs, the 'DAC' (Digital-to-Analog Converter) stage within the HeadRoom Desktop Amp/DAC allows the ability to connect any digital-based audio source directly to the amp via optical or co-axial S/PDIF digital inputs OR straight from any computer’s USB port. Go ahead and hook up everything at the same time -- up to five different sources -- and then select between them at the flick of a switch or two. That's amongst the many flexible "Audio Swiss-Army Knife" design features of our amazing HeadRoom Desktop Headphone Amp/DAC unit; The Desktop Amp/DAC can also easily act as an advanced switching center [i.e., 'pre-amp'] for all your various audio sources at home or on your workstation.
Features The front panel of the Desktop Amp/DAC sports both full-size 1/4" and mini-plug 1/8” [3.5mm] stereo headphone jacks for use with most standard headphone terminations. The amp will easily drive two headphones simultaneously. A 3-position gain switch on the front panel lets you select the operating range for headphones with any impedance or efficiency. Separate crossfeed and filter switches allow the user to adjust the audio presentation to your particular tastes and an On/Off power switch is also handily located on the front. The Desktop Amp/DAC has a rear panel connection for the +/-15VDC linear regulated standard AC power supply (included). The rear panel also has a 2 pair of RCA analog inputs with an input selector switch that allows you two analog sources connected to your Desktop Amp at all times. The Desktop Amp/DAC can also be used as a simple pre-amplifier and features a volume-controlled output on the rear panel suitable for use with powered bookshelf /computer speakers or for linking the HeadRoom Desktop Amp/DAC to a larger amplifier, pre-amp or home theatre system. The rear output can be defeated by a front panel switch when listening solely to headphones.
Electronics Module The 'electronics module' is the internal circuit board chiefly responsible for the amp's sound quality. The module found in the Desktop Amp uses Burr-Brown 2134 op-amps while adding a series of constant-current sources to force everything into true "Class-A" biasing. This 'Home' analog module is tightly coherent, seamlessly smooth, and very accurate-sounding with precise musical detail resolution, an ultra-wide dynamic range extension, and an expressive, nuanced musical presentation throughout the entire frequency range.
About the Digital to Analog Converter (DAC) A DAC allows your HeadRoom unit to accept any digital audio signal and convert it to warm analog sound using premium chip set electronics. The DAC then sends that converted analog audio signal to the headphone amp stage of the Desktop Amp for final clean amplification into your headphones. The DAC in the HeadRoom Desktop Amp is based on the excellent Cirrus CS4398 chip which is their top-of-the-line flagship DAC. There is frankly not too much we can do here at HeadRoom to make it sound even better but, as always, we give it a darn good shot. This installation offers superb overall audio performance from any digital-output audio source, an organic analog-like timbral smoothness, and cogent musical detail resolution while pushing the DAC stage into critical "Class-A" performance biasing. Accepts all valid S/PDIF formats up to 24/96kHz; USB to 16/44.1 kHz.
