The SLI 80 Signature integrated amp mounts KT88 output tubes and has a stated power of 80 watts per channel in ultra-linear mode, whereas 40 are the watts in triode mode. The Electro Harmonix 10 tubes are respectively two 5U4 Rectifiers, two 6922 Input Buffer Preamp, two 6SN7 Pre-Driver/Phase Inverter, and four KT88 Output tubes. On the front fascia, we have, from left to right, the on/off switch with a light blue led light, a small knob to select the three inputs, a big knob for the volume, another small knob for the balance, and the tumbler switch for the headphones. On the top sides are two tumbler switches - one for channel - to select the ultra-linear or triode mode of the output tubes. On the rear of the amplifier are two 4 and 8 Ohm switch settings to regulate the impedance. The binding posts to provide output to the speakers are on the rear panel, while more inside are the gold-plated RCA posts for the inputs and an output for a subwoofer, the fuses holders and the IEC socket for the power cord.
The bias of the output tubes is adjustable via two jacks, one for channel. It is possible to connect a meter plug that can read mAmperes.
The Cary is a powerful but refined tube integrated amp that can make you appreciate the music, all kind of music, with very high sound levels, in terms of tone colour and spatiality.
