ขาย Integrated Amp ยี่ห้อ Accuphase รุ่น E-303X (Made in Japan) ราคา 49,900บาท

ไฟ 220Volts

เป็นอินทิเกรตแอมป์ระดับ HI-END รุ่นใหญ่ มีเข็ม VU

ซึ่งพัฒนาให้รองรับความถี่ที่กว้างขึ้น เพื่อเข้าสู่ยุคของ CD แต่ยังคงเทคโนโลยีสำหรับฟังเพลงอนาล็อคได้อย่างครบถ้วย

Phono ได้ทั้่งหัวเข็ม MM & MC

กำลังขับ 150W + 150W @ 8 Ohms
