The DVA Digital Preamplifier is easily the best way to listen to digital media that AVA has ever produced — and is quite possibly the best anywhere.
For music lovers listening to digital sources, the DVA Digital Preamplifier provides a direct connection to the music — no analog preamplifier and its added colorations required. For everyone else, it makes for one hell of a DAC.
It offers both RCA and XLR differential (i.e., "balanced") outputs. Each signal after conversion passes through only one discrete, fully class-A active stage in a way that simultaneously minimizes the number of active stages the signal goes through while also retaining all the benefits of differential digital to analog conversion — for both RCA and XLR outputs.
Fully isolated USB, coaxial, and optical inputs. Touchscreen and remote control operated.
Everything you need. Pure and direct.
But this marvel of musical engineering nearly didn't make it to market. As we were finalizing the DVA Digital Preampliﬁer's design details, a massive fire at the AKM plant in Nobeoka, Japan rendered the audiophile quality AKM DAC IC it uses unobtainable. Fortunately, we were able to acquire a large supply of these wonderful converters before they disappeared from the marketplace after the fire. However, our inventory is limited. This may be your last chance to buy a full-featured audiophile quality digital preamp or DAC using these prized converters.
We are immensely proud of what we have accomplished with the DVA Digital Preampliﬁer. Calling it “stunning” is an understatement. Combined with our new DVA M225 or any of our other monoblock amplifiers, you'll experience digital content like never before.
Do you want support for your analog sources as well? Then check out our DVA A2D analog-to-digital converter.
Inputs: Five fully isolated inputs consisting of one galvanically isolated USB input, two transformer isolated S/PDIF RCA coaxial inputs, and two TOSLINK-style S/PDIF optical inputs. The USB input is Audio Class 2 (UAC2) compliant.
Stream compatibility: PCM up to 192kHz sample rates (coaxial and USB) or 96kHz (optical); DSD64, DSD128, and DSD256 (USB only). USB compatibility has been tested on Windows, macOS, and Linux operating systems. Windows users will need to install a no-cost and freely available driver for 176.4k-192kHz PCM and DSD support. Note: Currently DSD 256 will not work with Apple operating systems.
Output: One set of stereo differential (i.e., "balanced) XLR and one set of stereo RCA outputs.
Power: 120 VAC wiring is standard. For international use, a 240 VAC (50-60 Hz) option is available at additional cost.
