I've had this Arcam C31 Pre Amp for a few years of good service, and replaced it last year with the PS Audio BHK Pre Amp to match my other PS Audio Directstream DAC, player, and Power Plant. So its time to move it on to a good home. This model had a long life with Arcam, and was discontinued in favour of the Arcam C49. This C31 functions perfectly, with a good number of RCA input connections, but no digital inputs, you would need a separate DAC to cater for digital inputs. There are both RCA and XLR outputs. There are a few marks on the casework that I have shown in the photos - a mark near the headphone jack being the most visible where the headphone plug has repeatedly brushed the casework.
In my opinion the PS Audio BHK Pre Amp is more resolving of musical detail, but of course its costs a lot more.
The Arcam FMJ gear is very solid, and this is no exception. The volume control is well balanced and responsive, in fact a pleasure to use. The display is bright and clear.
The optional phono card has NOT been installed, I've always used an external phono preamp.
It comes with the remote, but no original boxes so I will pack carefully in generic packaging should shipping be required.
From the Arcam website at https://www.arcam.co.uk/products,c31.htm:
The C31 is a superbly transparent music preamplifier and provides a level of performance and flexibility that will delight even the most demanding music enthusiast.
With nearly 30 years experience in high fidelity audio design, Arcam has gained a world-class reputation for audio performance. The new FMJ C31 pre amplifier represents the pinnacle of Arcam’s achievements in stereo playback systems. When partnered with the FMJ P1 monobloc power amplifiers, it represents the very best of Arcam’s quest for ultra-high quality music playback and delivers a wonderfully faithful reproduction of even the most demanding source material.The design of the C31 features a simple, accurate and clean signal path. The reed relay input switching dispenses with the compromises of mechanical or conventional relay designs, resulting in switching with immeasurable noise and distortion. The studio grade electronic volume controls deliver precision variation of volume level whilst maintaining the subtle nuances of the music and delivering long-term reliabilityConnections are designed to be flexible with conventional unbalanced (for direct connection to power amplifiers and the purest fidelity), buffered unbalanced (for longer cable runs) and balanced output connections for use in electrically noisy environments. Inputs are wide ranging and include five line level inputs, two independent tape loops and an optional single stage MM/MC phono input .
All new audiophile pre-amplifier design with very low noise and distortion
Very short audio signal path for cleanest possible sound
No tone controls for lowest distortion and noise
DC coupled using servo to remove any DC from input signals
New improved Burr Brown volume control
High quality Burr Brown op-amps in signal path
Hermetically sealed reed relay input switching with immeasurable distortion and noise*
Four-layer printed circuit boards allow control of power supply reduction of electrical noise
Processor mode option for seamless integration with AV surround decoders
Audiophile grade Stargate and Rubicon capacitors for signal transparency
Optional single stage MM/MC phono preamp
* Note:- Because the contacts in reed relays are hermetically sealed, they can switch low-level signals as low as fempto amps and nano volts. Electromechanical relays cannot do this because they are not hermetically sealed and have polymer films build up on their contacts that require a voltage arc to break through this layer before conduction can take place. Similarly, semiconductors have capacitance, leakage currents and semiconductor offsets to deal with that introduce distortion and limit the switching and detection of low voltages and currents. Also, the reed relay has no moving parts and therefore, under signal conditions will switch greater than 50 million operations fault free. Electromecanical relays can at best switch up to the low millions of operations. Because its armature moves about a pivot point, wearing occurs, reducing life.
