Gospodine@vladd kažu da je sve u njemu prvoklasno počev od trafoa preko kondenzatora ….. ——- First and foremost, high-end audio starts with an outstanding power supply design, kill its noise at the inception, until it becomes a bigger problem down the road and that’s exactly what they’ve done with D1SE. SMSL added an IEC filter that already conditions the incoming AC voltage, a filtering stage follows and then a huge surprise: an audio-grade toroidal transformer from Noratel. As a small detour, I’ve had a Noratel transformer in my former Matrix Audio X-Sabre PRO ($1700), I have one in the Matrix Audio Element X ($3400), another Noratel in the Plixir Elite BAC400 ($1600) passive power conditioner and a huge one in the Elite BAC1500 ($4000). As you can guess, not all transformers are made the same, but the one used inside D1SE is a very special one that is being used only in high-end electronics. DC power coming from its transformer is then rectified and filtered multiple times with Nichicon KG caps and ultra-low-noise voltage regulators. At the heart of its digital processing, stays a powerful ES9038 PRO 8-channel DAC chip of ESS Technologies. This is their best and most premium converter. SMSL has plenty of experience with this chipset, as they used it in its predecessor (D1), in their M500 and SU-9 DACs. Thanks to the newest XMOS XU-216 interface that takes care of the USB input and to its higher processing power (2000 Mips) and RAM size, D1SE is capable of decoding and unfolding natively MQA material. It can fully unfold MQA files stored on your PC or played back via streaming desktop apps, as Tidal for example. There’s a Bluetooth 5.0 receiver on board that supports several codecs as SBC, AAC and AptX. Sadly, higher grade codecs as AptX-HD, LDAC and UAT are not supported, suggesting that it was put there mainly for convenience. Its antenna works as a wireless signal booster and its operating distance should be around 10 to 15 meters, depending on how many walls are in between both units (sender and receiver). All in all, SMSL D1SE uses only top-grade components, one of the best transformers, audio grade capacitors and a very capable DAC chipset and I expect some great things coming out of it. My ears started itching, so what are we waiting for? Let’s hit some eardrums! ——-
