Cyrus 8a Integrated Amplifier

The Cyrus 8a stereo amplifier delivers an impressive 70 Watts per channel and includes six analogue inputs which you can individually name, there's also a headphone output for private listening.

The Cyrus 8 series is the more powerful version of the Cyrus integrated amplifier ranges, with 70w/ch.

It has six analogue inputs, bi-wire speaker terminals, pre-amp outputs (for bi-amping) and a large, clear LCD display. Not only can you name each input, you can match them for sensitivity too.

Being a Cyrus, there is an upgrade path, should you so wish, starting with the PSX-R power supply and ultimately ending with the QX 24bit/192Khz DAC card.

The lively, detailed Cyrus sound is very much present in the latest 8 series but most importantly it has been balanced with greater weight making the Cyrus 8 a very fine sounding amplifier.
