WORLD PREMIERE! Tellurium Q Iridium Listen Headphone Amplifier. David Brook the proprieter of http://www.mains-cables-r-us.co.uk/ sent me an intriguing email announcing the release of a new product from Tellurium Q, but with no other details about this mysterious item. Being an inquisitive sort I asked for more information and David has kindly provided the details below. Tellurium Q Iridium Listen Headphone Amplifier. World's first demonstration at the UK Head-Fi meeting. £1236.00 Class A headphone amp with built in pre-amp. Two 1/4” headphone Jack outputs. With either output able to drive loading from 8Ω to 64Ω simultaneously. Thyristor memory controlled inputs. Hum rejection technology. Quad regulated power supplies. Headphone output driven by single ended class A power amplifier stages, please note that this is somewhat better than just an A class stage. Three RCA phono stereo inputs and one MP3 input via 3.5mm socket. Input loading impedance 47 KΩ for all inputs (so will take pretty much any input). Automatically selected Inputs controlled with a fifth isolated regulated power supply to further reduce the interference and noise floor. Photo's to follow tomorrow. Cheers, Andy.
