The IA4 is an all new discrete amplifier and as such is the baby of a new generation of our amplifiers using trickle down technology from its bigger cousins

SKU: N/A Category:


The IA3 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 coloured acrylic front, this allows you to match it with our range of TTs.

At its heart there is a strong power linear supply with RC multipole filtering, with regulation. It has a semi-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 50W 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 IA3 is available in the following colours: Black, Grey, Red, White, Green and Blue.
