Ultra-Portable DAC/Amp

Small enough to fit in your pocket. Powerful enough to play your music to its full potential. That’s the NuForce uDAC-5, a travel-friendly DAC/amp that—at just 3.5 ounces—makes it easy to enjoy high-res audio at home and on the go. The upgraded version of the popular uDAC-3, it offers twice the power and nearly twice the current reserves of its predecessor, and comes equipped with the ESS Sabre 9010 K2M DAC chip. Delivering clear, detailed sound with support for PCM up to 384 kHz, DSD 256, and DXD, it can be used as both a DAC and headphone amp—or exclusively as a DAC when you’re ready to make the switch to a larger, discrete amplifier.

About NuForce

Founded in California in 2004, NuForce was started by a pair of entrepreneurs who wanted to create amazing audio experiences at prices people could afford. Ten years later, to expand its manufacturing expertise, NuForce became part of Optoma, a world-famous projector manufacturer. NuForce’s earphones are conceptualized from the ground up by its top design and engineering experts, without using off-the-shelf designs like other manufacturers. Its products are known by audiophiles for their outstanding industrial design and sound quality. NuForce has also collaborated with Massdrop on two custom in-ear monitors: the award-winning EDC and the popular three-driver EDC3.

Sir, I suggest you read and comprehend posts before replying to them. 1) I said " Current limiting in amplifier design is not limited to protection against shorts ." I did not say current limiting factors are "not relevant." In fact, I said the opposite. I said (paraphrased) that there were several relevant current limiting factors beyond protection against shorts. 2) "Flat" frequency response is a relative and subjective term, especially if tolerance is not specified; i.e. +/- some number of dB. However, if you look at the peaks and valleys in the frequency response plots of the vast majority of headphones (or speakers, or any other electromechanical audio output transducer for that matter), and you consider that flat, then I postulate you wouldn't know a nice tittie if one motorboated you upside the head. Regardless, frequency response is irrelevant to my point and is not correlated to impedance. And, I would say that speakers and headphones have the widest FR variances of any component in an audio system. I would also say that this doesn't much matter to a large extent and many other factors have a greater impact on perceived fidelity. 3) Again, POWER by definition is voltage times amperage. One does not know the POWER output of an amplifier if only the VOLTAGE is specified. VOLTAGE only tells you the available rails before clipping. It is only part of the story. IMPEDANCE (not frequency response) is the AC approximate equivalent of resistance, and VARIES WITH FREQUENCY. The NOMINAL impedance of a speaker or headphone driver is an AVERAGE across the audible spectrum. At any given frequency, it will vary. Depending on the driver type, the actual impedance at any given frequency may vary significantly from the NOMINAL or average rating given. For example, my Martin Logan electrostatic speakers have a NOMINAL impedance of 8 ohms. But, this varies widely across the spectrum and at the upper frequencies the impedance is as low as 1/2 ohm. This is part of the reason why power testing into a dummy load such as an 8 ohm power resistor does not always translate well to an actual load. It is true that if there were no limiting factors upon current in an amplifier design, then one could derive the output power from the voltage rails and the impedance of the load, at least at a given frequency. But amplifiers often have many design constraints that limit the output current and thus prevent a given voltage from delivering the maximum theoretical amount of current into a given load. These can be power supply limitations, output device limitations, thermal protection, battery management, etc. Unfortunately, I don't have the time to teach an engineering course here, so if you have further questions I suggest enrolling in a basic electronics course at your local community college.
