The ES9038PRO SABRE DAC features ESS’ patented 32-bit HyperStream™ DAC technology with up to 140 dB – industry leading – DNR in mono mode and –122 dB (0.00008%) total harmonic distortion plus noise (THD+N). The HyperStream architecture is responsible for both the outstanding sound quality of ESS SABRE DACs and the extremely low THD+N. A typical competitive, 32-Bit 8-Channel DAC using a delta-sigma architecture features –107 dB THD+N (0.0004%), which when subjected to listening tests does not equal the clarity and sound stage of the ES9038PRO. </div> <div><br></div> <div><br></div> <div>여기서, 옛날 이야기 좀 하고 넘어가겠습니다.</div> <div><br></div> <div>옛날엔 dnr이 80db 이상이면 괜찮다고 했고, 90db넘으면 다 똑같단 시절도 있었는데</div> <div><br></div> <div>100db 넘기 시작하니, 고전적으로는 뭐 그리 고스펙이냐? 했고..</div> <div><br></div> <div>나무위키를 보아도</div> <div><a target="_blank" href="https://namu.wiki/w/%EB%8B%A4%EC%9D%B4%EB%82%98%EB%AF%B9%20%EB%A0%88%EC%9D%B8%EC%A7%80" target="_blank">https://namu.wiki/w/%EB%8B%A4%EC%9D%B4%EB%82%98%EB%AF%B9%20%EB%A0%88%EC%9D%B8%EC%A7%80</a></div> <div> <h3 style="margin:1.2em 0px .8em;font-family:'Open Sans', arial, 'Apple SD Gothic Neo', 'Noto Sans CJK KR', '본고딕', 'KoPubDotum Medium', '나눔바른고딕', '나눔고딕', NanumGothic, '맑은고딕', 'Malgun Gothic', sans-serif;line-height:1.1;color:#373a3c;font-size:1.6em;border-bottom:1px solid rgb(204,204,204);padding-bottom:5px;"><a target="_blank" href="https://namu.wiki/w/%EB%8B%A4%EC%9D%B4%EB%82%98%EB%AF%B9%20%EB%A0%88%EC%9D%B8%EC%A7%80#toc" style="background-color:transparent;color:#0275d8;" target="_blank">1.1.</a> Loudness war<span class="wiki-edit-section" style="float:right;"><a target="_blank" href="https://namu.wiki/edit/%EB%8B%A4%EC%9D%B4%EB%82%98%EB%AF%B9%20%EB%A0%88%EC%9D%B8%EC%A7%80?section=2" style="background-color:transparent;color:#0275d8;" target="_blank">[편집]</a></span></h3> <p style="margin-top:0px;font-family:'Open Sans', arial, 'Apple SD Gothic Neo', 'Noto Sans CJK KR', '본고딕', 'KoPubDotum Medium', '나눔바른고딕', '나눔고딕', NanumGothic, '맑은고딕', 'Malgun Gothic', sans-serif;font-size:14.4px;color:#373a3c;">이처럼 사람의 귀가 인지할 수 있는 다이나믹 레인지는 130dB이나, 1990년대를 기점으로 음역 전쟁이 시작되었다.<br>1990년 이전에 마스터링된 음원과 1990년 이후에 마스터링된 음원을 비교하면 컴프레서로 꽉꽉 채운 6dB 내외의 매우 협소한 다이나믹 레인지를 가지는데, 이는 단순히 ”음량이 크다” = ”소리가 좋다”라고 느끼는 수요층을 위해 무작정 음량을 올려서 내기에 음의 작고 큼 차이를 느끼기 힘들게 되었다.<br><br>그 외에 컴프레셔로도 완벽히 채우는데 실패햐여 클리핑이 발생하는 등 문제가 발생하기도 한다.</p></div> <div><br></div> <div><br></div> <div>사람 귀가 인지하는 범위는 130db정도 일꺼다입니다..(현재 기준)</div> <div><br></div> <div>실제로 90db 넘기 시작하면 현장감 생생하구요, 100db 넘으면 좋긴 한데, 비싸지기 시작합니다.</div> <div><br></div> <div>그래서 제가 산게 9018이였는데, 솔직히 9038 나올줄 몰라서 구매한것이구,</div> <div><br></div> <div>9018도 이보다 더 좋은게 나올수 없지 않을까?라는 막판 보스를 구매한다란 심정으로 구매했는데,</div> <div><br></div> <div> ess tech 홈페이지 가보니 9038 발표 계획이 있었고, 그 스펙이 보스급이 아닌 레전드 신급으로 더 이상의 고스펙은</div> <div><br></div> <div>나올수 없겠구나 하는 충격과 공포였습니다.(실제로 IC개발 팀이 회사를 퇴사해서 나올수도 없을거 같아요, DAC(IC말고 제품)만드는 회사 차렸음)</div> <div><br></div> <div><br></div> <div><br></div> <div>발표때는 ess홈페이지에 비교 스펙이 있었는데 오늘 보니 비교 스펙은 없네요.. </div> <div><br></div> <div>막귀는 9018이상이면 차이 느끼기 힘듭니다... </div> <div><br></div> <div>오유는 해드폰 사용자분들이 많이 오시는데, 해드폰도 레퍼런스/하이앤드 급 아니면 정확한 차이 느끼기 힘들 정도일겁니다.</div> <div><br></div> <div><br></div> <div><br></div> <div>하지만, 3만원짜리 번들 이어폰이라도 LG v2에서 쓰인 9018정도만 써줘도 </div> <div><br></div> <div>진짜 고음질을 느낄수 있습니다..
