Meanwhile, an often underestimated and hardly noticed device, but with the built-in technology and the construction with separate power supplies for each channel, an amplifier that can be a real insider tip at a used price of 200 - 300 euros (in good condition) probably. When it is outdated and you get to "feel" its full capacity, you know how much innovation the engineers have put into their work.

auftrennbare Pre-/power amplifier

Other models from the same series: the 8080 a whole is a year later, amplifier series emerged: SU-8099 as a top model (US price $ 1,000!), then SU-8088, etc.
The technology of the 8080 and the following series was much more innovative and complex than that of the *600 series with the SU-8600 at the top, which was still marketed at the same time as the 8080; this can be read both in the technical data and in the price. The SU-8600 was a good 100 US$ cheaper than the 8080 (460,- US$ 1978).
