Diamond offers connectivity for six digital sources and an external word clock. The superior VOLTAiR technology and the premium DAC with the unequalled DLP120 combined with an analog volume control allowing for highest resolution at any volume makes the Diamond an one-of-a-kind DA converter that delivers finest soundstages with an unrivaled analog feel. \u003c\/p\u003e  \u003cp\u003eThe 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.\u003c\/p\u003e  \u003ch3 id=\"toc_0\"\u003eSOURCE OF JOY\u003c\/h3\u003e  \u003cp\u003eUp to 6(!) digital stereo sources can be connected to Diamond. Diamond offers each a stereo USB and AES input as well as each two optical and coaxial stereo inputs. 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). The source selection is done via the selection control on the front. The selected input is also shown in the dot matrix LED display: USB, COA1, COA2, OPT1, OPT2 or AES After approximately two seconds, the display shows the type of clock source and the detected sampling rate. For example W192 = External word clock signal with sampling rate of 192 kHz.\u003c\/p\u003e  \u003ch3 id=\"toc_1\"\u003eALWAYS IN TIME\u003c\/h3\u003e  \u003cp\u003eDiamond can not only synchronize to the clock integrated in the digitally fed source signal. As a specialist for digital players, Diamond offers a word clock input. The source of the clock signal can be selected via the CLOCK switch.\u003c\/p\u003e  \u003cul\u003e \u003cli\u003eSource: Diamond synchronizes to the digital clock in the source signal\u003c\/li\u003e \u003cli\u003eWord: Diamond synchronizes to the digital clock present at WORD IN\u003c\/li\u003e \u003c\/ul\u003e  \u003ch3 id=\"toc_2\"\u003eWELL INFORMED\u003c\/h3\u003e  \u003cp\u003eThe DAC automatically picks up the sampling rate and resolution of the digital playback source. No matter if 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.\u003c\/p\u003e  \u003ch3 id=\"toc_3\"\u003eALL VARIABLE – OR SLAVE THRU\u003c\/h3\u003e  \u003cp\u003eDiamond provides two stereo output pairs for connecting power amplifiers or active loudspeakers. One pair of outputs with XLR, the other with 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.\u003c\/p\u003e  \u003ch3 id=\"toc_4\"\u003eTHE DAC\u003c\/h3\u003e  \u003cp\u003eThe 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 DAC in the Diamond is based on the SPL DAC768 – but offers not only one, but two coaxial and two optical inputs. Furthermore, it offers the possibility to be synchronized to external word clock signals via the CLOCK IN. Just like the DAC768, the Diamond uses the DLP120 with VOLTAIR technology. This is also the main difference to the smaller DAC768xs.\u003c\/p\u003e  \u003ch3 id=\"toc_5\"\u003eTHE DLP120 (DUAL LOW-PASS)\u003c\/h3\u003e  \u003cp\u003eEvery 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 and headroom and sound.\u003c\/p\u003e  \u003ch3 id=\"toc_6\"\u003eGREAT SOUND\u003c\/h3\u003e  \u003cp\u003eWith all devices of the Professional Fidelity series SPL 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 they can ensure they are using the best sounding components.\u003c\/p\u003e  \u003ch3 id=\"toc_7\"\u003eVOLTAIR – 120V RAIL TECHNOLOGY\u003c\/h3\u003e  \u003cp\u003eVOLTAiR 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. Technically especially in terms of dynamic range and headroom and sonically especially in reproducing the finest details and delivering a totally relaxed sounding audio experience. Music sounds absolutely natural.\u003c\/p\u003e","brand":"SPL Audio","offers":[{"title":"Default Title","offer_id":44450986164327,"sku":"207087","price":2219.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/spl-diamond-silver_186814_1_22800681-ae7e-4c67-b308-11214513b2c0.jpg?v=1787095378","url":"https:\/\/vintageking.com\/products\/spl-diamond-premium-dac-with-voltair-technology-silver-demo-deal","provider":"Vintage King","version":"1.0","type":"link"}
