All Tellurium Q products are designed and manufactured in Great Britain. Tellurium Q was founded by Geoff Merrigan after his visit to a recording studio in Somerset (UK). The main technical specialist of the company is Colin Wanfor, developer of amplifiers Claymore, Proac Magnum, Magnum, Dreadnought, Lescon, Oxford Acoustics. Wanfor is also known as the developer of the most powerful class A power plants: the TOCA SECA series, power sources for NASA.
The young company, which recently entered the hi-end scene, received a top score for the entire model range and awards for individual models from HiFi Plus and "Product of the year" from HiFi World.
HiFi World magazine states that the Iridium MM/MC Phono Pre Amp is “A stunningly good phono preamp that combines the best of solid-state and tube technologies. A market leader in its price category, Iridium will provide tough competition to phono stage amplifiers in much higher price categories."
The Tellurium Q Iridium MM / MC Phono Pre Amp is equipped with an adjustable output stage. There are two pairs of linear outputs on the back wall of the device. The first of these, labeled "Vol." It can be connected directly to the power amplifier and the volume can be adjusted with the potentiometer knob on the front panel. The second RCA pair is "Buffer" - with a constant output level. There are also two pairs of inputs – designed for MM and MC cartridges, respectively. The choice between them is made using the corresponding toggle switch. This allows you to connect two turntables or one turntable with two tonearms (with MM and MC heads).
