The IA4 is an exciting product for us as it represents the first evolution of our IA1 amplifier
It is housed in a full width but shallow depth aluminium case which has 6mm anodised front panel.
At its heart there is a strong power linear supply with RC multipole filtering, with regulation. It has asemi-symmetrical circuit topology for both the pre and power amplifier sections. As with all EA amplifier the inputs are switched by high quality relays.
The power amp section is a class AB 65W fully discrete design
It has 4 inputs, one of which a dedicated to an all new, fully discrete MM Phono (turntable) with the remaining 3 being for line sources such as CD, DAC’s, Streamers, tuners, tape recorders. There is a fixed output for recording or other slave devices such as an external headphone amplifier and a variable Pre-Out.
The front panel has a dedicated professional 6.3mm 1/4″ Neutrik headphone socket which switches off the loudspeakers when inserted. This is driven from the class A pre-amp output and not taken from the power-amp and resisted down, as is usual, this ensures the listener a much superior result.
Other possible upgrade options include an optional pre-amp output allowing you to upgrade with a better remote power amplifier like our P4/P5
The IA4 is available in the following colours: Black, Grey, and titanium silver
