Technics su co-4

For how long have you been using it?

3 years, everyday. Connected to a PC sound card shape with EMU 0404 USB or a CD.

I do not have a Technics turntable, but pretty well assured that side.

Have you tried many other models?

Yes, lots of other amps, but few are as well. Luxman (quite clear but lacks the trunk). Onkyo 8511 (good, powerful, but a little distant, more crashes as some switches Yamaha became real junk (Like the Onkyo, the rotary switch is remotely true stew very expensive).
Dates from 2000 and is already good for the break, he has yet costed candy to its buyer (I got it cheap, you could still block the switch, but once dead completely, no sound comes out) .. .
Nad: soft or sweet, a little blur the stereo ...

Pioneer AA 6 J Best, superb stereo, but it is more expensive. No feeling of superior power, however.
Pioneer A 219: quickly reduced, while its small, clean enough though.
Kenwood 4050 to MOSFETs: it is higher (larger and powerful, splendid treble) Reliable (date of march 91 and the fire of God, despite its remote switch). But is not low price, which is a problem when buying second hand. The manufacture of modern stereo amp under 300 € has become worrying when you open the hood you just want to close quickly, not to see the misery!

This is probably why people are looking for vintage amp ... making simple but reliable, normal: no questionable ingredients!

This little amp was purchased at a flea market with the risks that entails: it was dirty, spitting the knobs, switches, too. Two or three rounds of compressed air and a good clean contact with the bomb later, nothing seems. The construction is simple but serious, the modest power on paper, its size is rather small, it is quite beautiful, far from certain delusions 80s. It is already equipped with the ignition relay, which the HP good household.

The sound: dynamic, clear, almost clear, the bass is nervous without drought, acute own voices, saxes go with a good presence but without insistence. In short, as many amps Technics Class AA, it's really good. The sound is not projected while being very present, without fatiguing the ears.
In short, it's all good, the only small downside might be the stereo separation, which is not worth that of some big amps to power supply, but will be much more expensive.

Unimportant in nearfield ... and very little listening on a sofa, the sound image always remains credible.

The dynamic capacity to surprise an amp that is at most 2 x 40 W (watts of real, not like on some amps crumbling fast). With the small speakers to the average yield, no risk of running out of boot ...
Even pushing, you do not feel distortions.

It heats quickly and dramatically, it is characteristic of Class AA Technics, but it is still there, connected 12 hours a day, most of the time! At first I was afraid a little, well made but the radiators to ensure perfection.

If you find this price wise is a very good deal. Is however better to ensure that it works or make a good dusting / cleaning of the contacts (except the switch) if you buy it in a brac ...

Very happy with my Technics small ... I do not comment on the bass below 100 Hz, since my JBL Control One Pro repeat (+ One of the latest) does not pass at all and I added an amplified subwoofer Focal Cub2 ...
