Leak 2000

Clearly, this has been developed from the earlier and highly successful Leak Stereofetic tuner, and their Delta range of amplifiers. 30W per channel is available, in two selectable output loudspeaker pairs, which can also be connected in a pseudo quad arrangement with a push button, allowing different channel signals to be fed to the rear speakers. A stereo headphone jack provides a reasonable level for high impedance headphones, but much too high a level for 8 ohm ones (damage to the phones and your ears is possible!). A three core mains lead is provided, and two AC outlets (one switched) with European type round two pin sockets. All the input and output connectors are the appropriate DIN type, no phono sockets being mounted at all. Record output levels can be switched optimally for DIN or phono recorders. Inputs include pick up, auxiliary, cassette and mains recorder, the cassette input/ output not having monitoring facility. Balance, bass and treble controls have helpful centre indents, but feel rather rough. A series of flat push buttons incorporate a 12dB/octave treble filter (-3dB at 5.5kHz) FM mute (with variable mute pot) AFC, stereo width narrowing (FM), mono/stereo, input selection, loudness, tape monitor and speaker selection. A LW and MW AM section is also fitted, but no ferrite rod is available. A 75 ohm AMA coax socket is complemented by a 300 ohm balanced 2 pin one, and a separate AM terminal is fitted. The unit is housed in a wooden case with a metal base.
Although all normal laboratory measurements showed the amplifier section to be very good the subjective quality was at times rather hard, although bass frequencies seemed pretty good. The IM performance, for example, measured exceptionally well. A rather high dc offset was noted on one out put channel. The tracking of all the controls was at least reasonable. The treble filter was excellent. The pick up input performance measured extremely well, and had an excellent s/n ratio with a good clipping margin (two pick-up sensitivities switchable). All the general input and output impedances and levels were extremely well compromised, and compatible with sensitivity switching throughout. The tone controls had quite a wide range of adjustment and were well liked. For special uses the two outputs can be combined to give a very high power of 91W in to an 8 ohm load. A break point is provided (five pole DIN) for insertion of external equaliser. The loudness control affects only the bass, and was well liked. The amplifier became rather warm in use.
The tuner's RF sensitivities all measured extremely well, but the adjacent and alternate channel measurements were only average. The image response, RF, IM and local oscillator radiation were all poor. The capture ratio and limiting threshold were really excellent, and whilst the decoder gave amazing crosstalk figures at 1kHz, they deteriorated to average at high frequencies. Whilst the receiver was very good on weaker mono and stereo signals, strong stereo ones reproduced with only a very average s/n ratio. The multiplex filter was exceptionally good, as was response, although we detected slight over brightness in the presence region. A centre zero tuning meter is located behind the tuning dial, which was fairly accurate. The tuning knob was disliked, and was rather stiff. Subjectively the tuner sounded very good although the stereo distortion figures were just a little higher than average.
In general I liked this receiver, and it can be recommended, although I would like to see a quieter and better decoder fitted. The marginally below average amplifier sound quality showed up in some complex charts, producing noticeable IM peaks in the presence and bass region. If bought at a discount, reasonable value for money with excellent electromagnetic compatibility.
