The SA-610 was part of Pioneer's popular 'x' series of 1980-1981. The series was aimed at the mass market here in the UK and many of these amplifiers were sold in department stores as part of a full Pioneer system. Looks are subjective but I think these low profile units are prettier than Pioneer's more expensive offerings; they have the silver facia, metal controls and lovely blue fluorescent display without looking bulky. Inside, the amplifier is tidy with well routed cables, repairs should be easy.
Sound quality is very good for such a modestly priced amplifier. With the tone controls switched off, the sound is detailed and smooth without being forward or bright. Coupled with a Pioneer PL-71 and AT440MLB cartridge, the level of detail from vinyl is superb without sibilance. With my Bang and Olufsen CD player attached to the auxiliary input the sound is a little warmer. Bass is smooth and well controlled without sounding boomy or clinical; somewhere in the sweet spot.

Il date de 1979 et aucun craquement, aucun faux contact ! D'occasion, (40â‚¬) il me sert d'ampli pour mes écouteurs AKG 701. Il est très bon en valeur impultionnelle et sa restitution sonore est très dynamique. Sa note est de 9 sur 10 car il est comme tous amplificateurs de cette époque : son alimentation chauffe sa carrosserie, il aura besoin d'étre bien aéré.
Je conseille vivement son acquisition qui permettra de posséder un appareil très performant et très beau pour pas cher, de plus il est construit pour durer et une réparation éventuelle sera facilitée par ses composants très courants.
It is 1979 and produces no cracking, no bad contact! Used (â‚¬ 40) it serves me for my AKG 701 headphones amplifier. It is very good in impulce value and its sound reproduction is very dynamic. His rating is 9 out of 10 because it is like all amplifiers from this period: its heating power its body, it will need to be well ventilated.
I urge that the acquisition will have a very powerful and very beautiful machine for cheap, plus it's built to last and any repairs will be facilitated by its very common components.

Rating considers expectations for a 45 WPC unit. But note that I do have a perfect SX-1250 that I compare everything to... so as to the sa610, I have it connected to the sg 50 and the rg2, and driving hpm100s. I have to say this little thing is amazing for its size. I bought it because I LOVE the aesthetics of this Pioneer line... gorgeous. But I never expected it to perform so well with my system, normally driven by the SX1250. I love the sa610 so much I am shopping the same models in more power. But truth is I use the sa610 more than the sx1250. Unless I want to crank to disco levels, this little 610 is superb.
