저번주에 거금을 들여 구입하여 또 거금 주고 (ㅠ.ㅠ) 오버홀 완료한 리시버 입니다.. 원래도 상태가 좋았지만 지금은 더 반짝반짝 합니다.. ^^ 2500리시버는 몇 번 본적이 있지만 2600은 첨 입니다.. 참고로 78년도 출시가가 1600불 입니다.. (2285가 670불, 2325 800불이니 꽤 비싼기기죠^^)


4312SX 를 2285에 물려서 썼는데 항상 평퍼짐한 저역이 불만이 었습니다만 이넘은 아주 단단한 저역을 들려주는 군요.. 그리고 제가 써본 튜너 중에서는 최고 입니다.


아마도 마란츠 2130 최상급 튜너가 내장된 모델인듯 합니다. 2500리시버는 2110 튜너 인듯 하고요.. 큰 차이는 Qquartz locked 되고 안되고 있듯 한데 자세히는 모르겠습니다..


하여튼 너무 마음에 들어서 아침 저녁으로 먼지 털어주고 만져주고 난리도 아닙니다.. *^.^* 우드 케이스를 입히고 싶은데 우드 케이스 제작비가 만만찮네요..





2,3,4 번째 사진은 전주인의 사진을 허락없이 퍼온겁니다..





전면 모습입니다.








후면 입니다. (돌비 디코더가 없고 대신 AUX가 2개인 EURO 모델입니다.)





내부 모습입니다.. 커다란 트로이달 트랜스가 보이네요


요즘 메인 시스템입니다.





마란츠 2245 도 보이네요.. 미국 생산품입니다..


소니 501ES 시디피와 하만카든 CDR-20 입니다. 가격대비해서 괜찮은 기기들이지요
