REAL-PHASE System = exactly the same phase position of the two stereo signals for the perfect sound purity and fidelity of a digital music recording
on-delay Relay
the power amplifier switch-Off in case of Overload of the speaker
The position settings of the direct selector switch (switched) are back-lit

In the case of a second-hand purchased (07/2012) everything runs great, only the Volume Knob crunches a little. Rich and clean performance, with CD Direct there may be a little bit of bass (subjective) but this can be compensated for by bass and double bass (no longer CD Direct).
Also (m)an amplifier that was used in the late 90s has always been running flawlessly and completely reliably without any problems (this is probably also a result of the fact that it was never stored in a [damp] storage room / cellar).
For purists, an all-round great (real) analog amplifier without any A/D converters and servo drives (remote control).
Otherwise very cleanly processed and even after more than 20 years old new optics!

My A-8470 is powered by a Cambridge DagMagic 100, so I can connect all input devices digitally and have a smart digital-to-analog conversion through the DAC. A top pairing with an ELAC 211.2 SUB and a looped Canton Vento 820, the 211.2 has a high-pass filter when looping through, so the Canton have no problems with too low frequencies that the 211.2 top makes anyway. The value of the Integra is mega, the switches and connection terminals are all of very high quality. Only after 15 years of standing he had problems with the potentiometers, but the Integra itself can't do anything for that. I have now "used" everything again. Muting has contact problems when he gets warm.

Taken over in 2019, pots were no longer clean, even channel selector switches A/B had unclean contact
No contact spray, simple use was enough
Clean beautiful stereo sound full
Top haptics, very valuable
