The HA-DSP is a revolutionary new headphone DAC/amplifier from miniDSP. As well as providing three inputs (USB/Analog/Toslink), the miniDSP HA-DSP features a hitherto-unknown level of digital signal processing power and flexibility in a headphone amplifier: simple bass and treble adjustments, ten fully programmable parametric equalizer bands per channel, and a revolutionary FIR filtering/cross-feed matrix that allows implementation of extremely sophisticated headphone correction and cross-feed algorithms.

All this power is delivered by a 500MHz XMOS multi-core processor and a 400MHZ SHARC DSP. The onboard firmware is designed to seamlessly interface with laptops and desktops, iOS devices, and Android devices. And any other source can be connected via the analog input or optical digital input. When it comes to USB audio streaming, the HA-DSP supports both PCM and DSD formats. Housed in a lightweight and compact enclosure, the HA-DSP can go anywhere you can. Its 3300 mAh battery provides ample power — enough for a full day (ten hours) of listening. The combination of DSP power, careful selection of high-quality components and a 32-bit ESS audiophile-quality DAC combine to create an unparalleled portable headphone experience.

After I read through your excellent documentation I set up a 'no-gain' profile in the parametric EQ to correct for most of my asymmetric hearing loss and when listening through my high-end headphones I was very moved to be able to hear the veil removed from music that I have known and loved, even with the hearing loss. Also, movie sound tracks rock! I just didn't know what I was missing! Feel free to quote me on this as a recommendation to others who may have the same issue. Yes, it's a bit of a learning curve but it's worth it! The HA-DSP is now my constant companion on whatever I listen to on headphones.

A fantastic product! Got it and the EARS recently, and they worked together fabulously. Took me a while to get REW and the plugin to work with each other, but that was much more a problem with me and not the product(s). Using them individually, they were surprisingly easy to use. These have provided a massive improvement in quality, honestly aside from spending exorbitant sums of money on speakers and equipment to run said speakers, this is the best you can get. I only have some $60 Corsair headphones and they , in conjunction with the HA-DSP, easily compare to some thousand dollar speaker systems I have heard. Quite the bang for the buck. The only negative I could bring up about the device is how bulky it is and how short the connection cables for 3.5mm are, about 6 inches, not able to get to anything. This leaves my unit hanging awkwardly from my computer seeing as the cable it to short to reach the ground. This is quite easy to remedy with a quick purchase of a slightly longer cable. The unit itself isn't bulky to the point of being unbearable, but it is about the size of a large phone, think a thicker Iphone. All in all, I would give this product a 9.9/10 star rating, it's only detractors being it's slightly bulky size and the short cable provided. For the price I give it a solid 11/10 for reasons described above.
