Meet the all-new HiFi audio decoder from the house of S.M.S.L, the D300 featuring flagship-grade BD34301EKV DAC chip from ROHM technologies. It is fully optimized to take full benefit of the premium audio chipset providing high-resolution audio signal decoding with ultimate precision and low distortion ratings.

BD34301EKV DAC overview: 

The BD34301EKV DAC chip, developed as part of ROHM’s high-grade MUS-ICT™ series representing the pinnacle of audio ICs, emphasizes ‘spatial reverberation’, ‘quietness’, and ‘dynamic range’ – qualities important for reproducing classical music. Original sound quality design technology makes it possible to successfully reproduce the target sound quality by incorporating a circuit in the signal processing block to check for audio quality. At the same time, class-leading low noise and distortion (130dB SN ratio, -115dB THD+N) provide the high performance demanded by high fidelity audio equipment. At last, the customizable digital filter – a key function of the digital signal processing circuit – supports the creation of the ideal sound sought by audio equipment manufacturers.

ROHM's Flagship Audio Decoding Chip:

S.M.S.L has packed impressive performance with the D300 by featuring ROHM's flagship BD34301EKV audio decoding chip at its core. They have professionally adjusted the DAC tuning to take full benefit of it in delivering quality performance. It has full support for high-resolution 32-Bit/768kHz PCM and native DSD512 decoding with the help of an XMOS XU208 high-quality 8-core USB processor.

High-Resolution Bluetooth Support:

One can simply feed high-resolution audio signal input to the D300 using a wireless Bluetooth connection. The D300 adopts the latest Bluetooth processor chip from Qualcomm providing it with Bluetooth V5.0 connectivity. It supports high-resolution wireless transmission codecs including LDAC, AptX HD, AptX, SBC, and AAC.

Equipped With Ultra-Low Jitter Clock System:

S.M.S.L has featured their new CK-03 ultra-low jitter clock system with the D300. This enables ultra-low jitter for the signal across all the available inputs with the D300 that includes USB, Coaxial, Optical, and Bluetooth. With ultra-low jitter in the output, the output quality is simply top-notch.

Specially Designed Discrete Component Low-Noise Power Supply:

S.M.S.L has designed a special discrete component stabilized power supply for the D300. It provides noise-free operation ensuring each component on the analog and digital circuits receives proper power. It is optimized for better efficiency with lower power consumption. To protect the power supply from any outside interferences, S.M.S.L has given it a properly shielded structure.

AKU menulis ulasan sebulan setelah perangkat datang padaku. Di pertama dari kotak tidak terkesan dengan suara. Suara dikompresi, sederhana di seluruh rentang. Kesimpulan tergesa-gesa memutuskan untuk tidak. Pergi di pagi hari untuk bekerja menarik folder dengan Nas dan meninggalkannya untuk bekerja untuk seluruh hari. Di malam hari dia pergi ke kamar segera tertangkap yang pakan telah berubah. Setelah seminggu mendengarkan secara aktif, perangkat seperti yang mereka katakan hangat sekarang suara menyenangkan. Bermain sangat mirip dengan my multibit, suara, detail lebih tinggi dari multibit, banyak rincian menarik keluar dari trek. DAC merekomendasikan untuk uang ini dia memiliki sangat sedikit pesaing. Dia perlu pemanasan, keluar dari kotak tidak suara yang akan. Untuk penjual terima kasih khusus, Diskon, dengan cepat dikirim, dikemas dengan baik.

Kotak ini datang padaku. Sebelum dia di DAC sistem Sabre 9018 dari brizaudio, yang berdasarkan rekomendasi dari tahun delapan yang lalu mengambil untuk $500. Dan apa yang AKU katakan, teman. Ini adalah kotak besar! Setelah Sabra dan versi 9018 salah satu yang terbaik adalah dianggap memiliki musik tidak besar jumlah suara berkualitas. Ada emosi. Dan tidak ada keinginan untuk segala sesuatu yang datang dari kotak, menganalisis. Ada seluruh suara emosional kain. Untuk Uang Anda adalah pilihan yang sangat baik. Setidaknya saya. Dan ini yang sumber dalam bentuk yutuba atau Yandex musik di film pencarian. AKU punya kotak terhubung ke TV kaca optik. Selanjutnya, top Yamaha B70 + C70. Speaker Dynaudio fokus 220mk2. Pasti merekomendasikan.
Dan penjual. Dikemas dengan baik. Cepat dikirim.

Di Rostov na Donu disampaikan dalam 32 hari oleh Courier Mail. Melalui 2 lapisan pusar, kotak kusut, tetapi perangkat tidak menderita.
Terhubung ke smsl ho200 headphone amplifier dan Yamaha HPH Mt5 headphone melalui ASIO driver. Dan tidak mendengar perbedaan dengan Cina CPU amplifier ayima A5 pro. Trek MP3 320 dan FLAC. SAYA akan mencoba lain headphone. Dan mungkin hanya mendengar tidak berbeda perbedaan. Meskipun perbedaan suara dari kartu Behringer 204hd terdengar. Secara umum, jika ada perbedaan suara kemudian mereka tidak 10 kali harga perangkat
