Macchina di costruzione davvero robusta, suono davvero sorprendente per l'età. E' un amplificatore che sembra avere più dei 40 watts dichiarati e ha un punch e un dettaglio molto buoni davvero! Anche il sounstage appare ampio e dettagliato. Ne convengo che i Pioneer degli anni '70 non erano solo belli da vedere. Mi devo ricredere. SA-7500 mk1

A very solid performing amplifier- Rich and detailed highs and nice low's - No clipping or distortion with equalizer, turntable and PC input. Used every day, daily, with a pair of Burhoe Blues, nothing i can really say bad about it, rather than its where it should be for terms of the class and time era of the amp performance wise. Better money better amp. But you won't find this Simplicity, and value with performance. The SA-7500 MK2

I have mk2 in a setup with a CTF-850, a TX608, a TEAC reel to reel A-3300, a project TT and JBL Arena 180 speakers, it sounds very well. Balanced, powerful and very low distortion. Is a well build amp but i regret the fact that is designed narrower compared to classic amp components (38cm instead of 42cm). Even mk1 was the classic 42cm size. But it is really smooth even in operations, with volume knob clicky and smooth.

Super petit ampli, je possède la version II .
Après un traditionnel changement de tous les condensateurs, le son est très fin, fluide et petit plus, possibilité de by passer l equaliser.
La puissance est suffisante avec des enceintes assez sensibles, type Klipsch Heresy.
Je découvre la gamme Pioneer de cette époque et apprécie la qualité générale et la possibilité de pouvoir effectuer les rénovations sans être un pro de l électronique.

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.

re: SA-7500

Sounds a teeny bit better than my 7500II with my Pioneer PL-518 TT. Is the 7500 superior to the 7500II ? Anyways, got my SA-7500 for a cool $50 (Canadian) last night. Playing Vivaldi - sublime.
