Awesome amp ! It's 40 years old but you wouldn't know from the very modern-sounding wide soundstage. Built like a tank. Construction is very clean and orderly with high-quality parts save for only the cheap potentiometers (4) used to adjust bias and offset. I replaced mine with multiturn, sealed blue pots - far easier to adjust and much more stable. The thick aluminum engraved faceplate is truly beautiful. Not to be confused with the much-inferior MK2 model with its inferior phono-stage op-amps and noticably cheaper construction.

Possiedo un 7500 prima serie. Qualità costruttiva ai massimi livelli in ogni particolare: 2 ingressi Phono, separazione pre-finale. Ottimo suono.

strong, punchy sound despite low watts rating
