Musical Fidelity X-Pre, £200 ,Jan 98 ,A smooth, sweet and musical performer.
The X Series from Musical Fidelity, from which the X-PRE and X-A50 are drawn, includes a number of purpose-specific modular hi-fi components. JK reviewed the X-PRE preamp in HFC 166, while SV tackled the X-A50 power amplifier monoblok in HFC 169. On the latter's outing we clocked power output at 65 Watts continuous into eight Ohms. It uses a quasi-complementary bipolar output stage, with paralleled sockets to permit daisy-chaining into other monobloks and therefore bi-amplification.
The X-PRE claims to be a Class A, single-ended-triode design based on KT-88 valves. That would make it about as purist a product as they come, though there is no external indication at all that the X-PRE is tube-powered. There are four line inputs and a volume control (both nail-breakingly small and fiddly) and no tape circuit. It hooks up to the mains via a plug-top transformer.
By way of interconnects we deployed
M-F's own X-LINX wires (?0 per pair).
Sound quality
The combination registered an indifferent average score across two presentations to our panel, with the hands-on listening sessions suggesting that the preamp's power supply was a significant drag on system performance, preventing the X-PRE from 'breathing' freely with recorded dynamics. Among other effects, this reduced perceived stereo separation. The ?30 X-PSU power supply, though not officially part of the test, did enhance performance, limiting the perception that musical detail was being homogenised. There was more space and 'air' to the sound, and tighter bass.
The following panel comments, however, refer to the preamp's performance with the plugtop PSU. One common observation was of a "refined, spacious... yet slightly hard quality in the Mozart Wind Serenade" (referring to the upper registers). But there was a persistent complaint that the sound was rather soft in the lowest octaves - one listener even described the bass as "cardboard-like". There were occasional moans of lacking definition, and one listener speculatively wrote that the combination had a "Class A valve-like" quality. A particularly perceptive comment: the preamplifier does tend to dominate the mix, especially with the supplied power supply.
My own listening confirmed an impression that the rather warm, distant balance of the Tannoy D500s was not ideally matched to this combination. The X-PRE/X-A50 rig really comes into its own with big, clean, dynamic speakers, especially the Definitive Technology BP2002 and Mirage OM-6 (both lively, engaging transducers), and even the big Tannoy Definition D900s. The latter sounded surprisingly grown-up and lifelike hooked up to these cylindrical chassis.
Conclusion
The build quality of these components is excellent; their configuration most flexible. The three-strong assemblage may be expanded in numerous directions as desired, for example by adding an improved power supply, tone controls, or a phono stage. Simplicity and value for money are its principal assets, however.
Taking this into account, and allowing for the effect on panel-test results of an unfavourable loudspeaker, Musical Fidelity's trio earns a Recommended tag. That snazzy little support bracket in the photo costs just ?0 extra, by the way!
