Esoteric F-03A integrated amplifier with phono stage
Esoteric F-03 integrated amplifier
The Esoteric F-03A is the second to top of 4 models in the Esoteric integrated amplifier range. Functionally it is similar to the F-05 with the same inputs outputs and other controls. On the front panel some features are now concealed behind a fold down fascia. The main difference however is the output stage. The output stage on the F-03 is class A and as a result power output is reduced over that of the F-05 and F-07. This makes the F-03 more suited to higher sensitivity loudspeakers.
The Esoteric F-03A offers a great range of inputs and outputs and 30 WPC into 8 ohms and 60W into 4 ohms The substantial amplifier weighs in at over 32Kg and inside is effectively dual mono construction with the exception of the transformer. The power supply is based around a custom 940 VA EI core transformer. This feeds 4 separate diode bridges and then 8 substantial smoothing capacitors. Each power amp channel is based around a huge heatsink and rather than using tracks uses large bus bars to transfer power more effectively. Each power amp channel has substantial venting in the case to allow cool running.
The Esoteric F-03 has a built in switchable phono stage. It will work with both Moving Magnet and Moving coil cartridges. Line inputs can be connected via RCA or XLR connectors. There is also a pre-amp output on RCA and XLR connectors. The font panel of the F-03 features a set of concealed tone controls, these can be bypassed if required. The F-03 can also drive a set of headphones via the connector on the front panel. It is a very capable integrated amplifier and only the Grandioso F1 outperforms it.
