블루투스 신호잡음도 없이 깨끗하게 잡힙니다 이외 usb, u-disk 등 입력장치가 있어 소스 선택에 만족 프리앰프의 출력+액티브스피커(Edifier1)언결 사용중 모니터 출력용으론 멋진 조합입니다

본제품은 가격대비 성능이 최고인 제품이며 사용하기 편하고 헤드폰단자가 있어서 범용성이좋으며 블루투스인식이 빠릅니다! 진공관앰프에 프리앰프로 사용해도 뛰어난 음질을보여주는 가성비 짱인 제품으로 전 3개구입후 동생,친구 에게 선물하였고 너무도 반응이 좋았습니다! 강추합니다!

이상없이 작동중. 파워앰프 단독으로 사용 할 때는 소리가 산만하고 중역이 부족, 정돈이 되지않았으나 프리앰프의 트러블과 베이스를 조절하고 사용하니 소리의 균형이 잡히게됨. 진공관의 에이징이 되고나면 더욱 개선 될 것이라 생각됨. 지터의 개선은 어느 단계에서 해야 할지 고민중. 저렴한 가격으로 잘 샀음.

шикарно. звук поменял реально окраску, в лучшую сторону. при этом лампы еще даже не прогрелись. у меня первый опыт с недорогой hi-fi техникой, но он положительный. спасибо продавцу.

Zeer goede Bluetooth ontvangst en weergave. Effectieve toonregeling voor kleine correcties zonder vervelende scherpte of hol laag toe te voegen. (Dat zeg ik terwijl ik geen groot fan ben van toonregeling voor thuisgebruik) De behuizing is volledig van aluminium met een dik front! De verpakking is maatwerk schuim, erg goed! De bezorgtijd naar Nederland was 8 dagen.
