Increcable - iAmp TIA-260R - Reference Series Tube Integrated Amplifier (Set)

Increcable - iAmp TIA-260R - Reference Series Tube Integrated Amplifier (Set)

The iAMP amplifier was designed to provide a significant value based on a high performance to price ratio that will exceed the sonic quality of good solid state amplifiers with its musical accuracy.

TIA-260R Reference Series Tube Integrated Amplifier

30 watts x 2 (Triode), 60 watts x 2 (Ultra Linear), KT88 x 4 / 6SN7 x 2 / 6SL7 x 2 ( All Matching DCT tubes )

DCT Choke, DCT Pure Silver internal wiring for audio paths & Power Cord

Deep Cryogenic Treatment DCT Tube

The process makes a permanent change and the benefits do not deteriorate over time or upon return to operating temperature, it changes the whole way the vacuum tube performs. The major benefit has been a dramatic improvement in dynamic range, micro detail with an increase in speed. Bass response has been clearer with a reduction in micro phonics. The proprietary DCT treatment process utilizes a computer controlled, cryogenic chamber to very gradually reduce the temperature of the tubes to 300 degrees below zero (Fahrenheit) and holding them there for a minimum of 24 hours. After the extended dwell at this cryogenic temperature, the vacuum tubes are then very slowly brought up to ambient temperature over the next 24 hours and stabilized. All these processes are microprocessor controlled under strict and verifiable conditions.
