The Ref.3 is not an update or a minor revision; the Reference preamp has been redesigned from the ground up, and Ref.2 Mk.IIs cannot be updated or retrofitted to Ref.3 status. On the outside, the obvious change is a major evolution in front-panel design. From time immemorial, ARC has favored, to put it gently, plain-Jane cosmetics. The Ref.3 breaks new ground and is a leap into a graceful, almost Goldmund-like 21st-century minimalist aesthetic. The preamp’s few controls and large vacuum-fluorescent display, easily readable from a considerable distance, make a striking impression.
The rear panel is the same as the REF2 except for the deletion of the tape monitor input. The REF3 does not have the ability to listen to one source while taping another. Also, the IEC connector for the removable power cord has changed from 15A to 20A.
The remarkable level of performance has been achieved with all new audio and power supply circuits. There are four new circuit boards and two new transformers. The new audio circuit is pure tube, Class-A, with zero feedback, utilizing a total of four long-life 6H30 twin triodes. FETs are used for constant-current sources (outside the single path), and the analog circutry uses a long-tailed pair input stage to provide the same performance in either single-ended or balanced operation. Total gain is 12dB balanced, 6dB single-ended. The hybrid power supply has over 50% greater energy storage that its predecessors, greatly contributing to its tremendous dynamic capability. There are other improvements which can be seen on the bench and appreciated in the listening room. Bandwidth has increased from 60kHz to 200kHz; noise has been reduced by 12dB; headroom is much higher, with the maximum input increased to 20V balanced, and distortion has been lowered by 40%. The advancements of the REF3 are both audible and measurable.
