If you need top audio playback quality from your digital sources, look no further than the silver Diamond from SPL, a premium DAC and preamplifier designed to handle digital audio from multiple types of sources and reproduce them with impeccable accuracy. With support for up to 32-bit / 782 kHz digital PCM and DSD250 audio decoding through the AKM AK4490 DAC and analog DLP120 dual low-pass filter chips, the Diamond can deliver the full sonic character of any digital source while also making sure no beat is out of step thanks to the ability to select between the clock from the digital signal or a dedicated BNC word clock input.

Flexible digital input options include AES XLR 3-pin, two S/PDIF RCA coaxial jacks, two optical TOSLINK S/PDIF jacks, and a USB-B port, which provides the highest sample rates, while balanced XLR and unbalanced RCA outputs are provided stereo analog connection to your speakers or mixer. The innovative onboard VOLTAiR technology and shielded toroidal transformer delivers superior rail voltage for the internal circuitry, ensuring that the Diamond provides the highest quality audio experience possible by vastly improving dynamic range, distortion, SNR, and maximum gain levels.

Everything Under Control

The volume is adjusted with a solid, milled aluminum, rotary knob. The Alps RK27 Big Blue potentiometer gives a pleasant spoon in the honey rotary feel.

Six Stereo Sources

Up to six digital stereo sources can be connected to the Diamond, making this DAC/preamp an ideal heart for any digital audio system. Diamond offers both a stereo USB and AES input as well as two optical and coaxial stereo inputs. The selected input is also shown in the dot matrix LED display.

Via USB, both PCM audio and DSD audio can be converted. PCM audio is received in S/PDIF format, both coaxial (RCA), optical (TOSLINK F06) and balanced (AES/EBU).

Always in Time

Diamond can not only synchronize to the clock integrated in the digitally fed source signal. As a specialty for digital players, Diamond offers a word clock input. The source of the clock signal can be selected via the clock switch.

Well Informed

The DAC automatically picks up the sampling rate and resolution of the digital playback source, regardless of whether a streamer, computer, CD player, or an external word clock is connected. The detected sampling rate and the selected clock source are shown in the dot matrix LED display. For example, U768 is an acronym for a clock signal in the USB stream with a sampling rate of 768 kHz.

All Variable or Slave Thru

Diamond provides two stereo output pairs for connecting power amplifiers or active loudspeakers. One pair of outputs utilizes XLR 3-pin connectors while the other uses RCA outputs. Both have the same output signal, which is controlled by the volume control on the front panel.

The volume control for the RCA outputs can be switched out of the signal path via DIP switch on the back of the device. For example, a headphone amplifier with its own volume control can be connected to one of the outputs.

The DAC

The highly acclaimed AKM AK4490 Velvet Sound premium DAC chip is used as the converter chip in the digital-to-analog converter, which thanks to its architecture reproduces the finest sound details. It converts PCM audio with a resolution of 32 bits and a sampling rate of up to 768 kHz, which is equivalent to 16 times CD resolution. Direct Stream Digital is also supported up to resolution of DSD4 or DSD256.

The DLP120 (Dual Low-Pass)

Every signal that is passed from a DAC chip into the analog world must be filtered be filtered by a low-pass filter. Two of them are implemented in the DLP120: One for PCM audio and one for DSD audio, since different roll-off frequencies are required. In contrast to all other DACs in the world, the low-pass filters here are built using VOLTAiR technology, which provides a plus in dynamics, headroom, and sound.

Sounds Great

With all devices of the Professional Fidelity series, we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way, SPL can ensure that they use the best sounding components.

VOLTAiR: 120V Rail Technology

VOLTAiR is the synonym for SPL's 120V Rail Technology within the Professional Fidelity series. The audio signals are processed with an unequalled ±60V DC, which corresponds to twice that of discrete operational amplifiers and four-times that of semiconductor operational amplifiers.

VOLTAiR Technology reaches outstanding technical and sonic performances, especially in terms of dynamic range, headroom, and in reproducing the finest details and delivering a totally relaxed sounding audio experience. Music sounds absolutely natural.

This is a must-read for all those who are seeking answers.
Format: Paperback
If you can read only one of Robert Monroe's 3 books ("Journeys Out of the Body," "Far Journeys" and "Ultimate Journey"), "Ultimate Journey" is the one to read. Monroe's books chronicle his amazing learning experiences as his ability to travel out of the body develops and his capability to remember and to put these odysseys into words increases. Without laboring over material covered in the first two books, Monroe sums up his earlier adventures and then writes about his most recent and significant discoveries on this, his spiritual journey to understanding. If you have ever wondered if there is a God, why the Bible says that God is Love and in another place, shows God to be a vengeful being who orders the killing of many people, "Ultimate Journey" and the lessons taught to Monroe in his out-of-body state will help to clear up these questions. To say that "Ultimate Journey" will give you a whole new perspective on life, death and what lies beyond is an understatement. This is a must-read for those who are seeking answers! And, if at all possible, read all 3 books in order. "Far Journeys" is definately the most difficult to read, since much of it reflects Monroe's efforts to translate non-verbal communications from non-humans into English. But the information in that book is voluminous and well worth the effort to read it. Happy reading, fellow seekers!

YOU can actually LEARN to do this!
Format: Paperback
"Eavesdropping on Animals” by George Bumann really was a welcome break for me as I spend so much time outside in Nature. George is also amazing at being able to read Nature in a way I had never seen before. His insight via really listening & paying attention to everything around him, is so precise - he can literally know where animals are without seeing them. I got this book mainly because HE wrote it & I knew it would be interesting. The thing that surprised me was he actually teaches you how to do what he does (ie: know exactly where a wolf pack is traveling by hearing a certain coyote call & knowing the terrain). I started simply by really paying attention to all of the bird songs going on outside my window very early each morning & could finally hear ones that were repetitively there & was able to figure out what they meant by getting outside & sitting on my patio as I drank my tea. If you LOVE NATURE, you would so get into this book. It’s a great teaching guide, plus his stories are so cool! Entertaining & informative to read.

Will forever change your experiences in nature!
Format: Hardcover
I am an instructor in animal language in the wildlife ecology department at two leading universities and I can attest that George is an expert animal whisperer/linguist. I've had the pleasure of knowing him and hearing his stories, and this book is an outstanding gateway into understanding the behavior of animals. It will reveal a whole new world to you every time you step outside, whether you live in an urban area or next to a wilderness.
