Opera Consonance Reference 6.6 Tube amp

I am selling my amp due to the purchase of new one. I have just replaced the tubes with new KT88`s. The amp is pretty much perfect condition rating will be do to age only. This amp has run a variety of speakers with no problems ( monitors / planar / electro statics) This amp will also come with a much nicer power cord then provided by the factory.

pera Audio have thought to design an integrated amplifier around a product they regarded as particularly good from the musical point of view, the GEC KT66 replica tubes manufactured in China by Guiguang of Guangxi, implementing around them a push-pull circuitry. The driver stage uses a pair of Sovtek 12AX7LPS and a pair of 60s NEC 12AU7 NOS. The power supply is delivered by a toroidal transformer while the output transformers are the same ones used for the most prestigious range of the brand (Signature).

The technical specifications declared by the manufacturer are the following:
