Pro-Ject Phono Box MM, Phono preamplifier with metal case and special low-noise ICs

Product Information

You can read more about how we test and review products on What Hi-Fi?here. Why do I need a phono stage? Engaging the subsonic filter (also available via front panel pushbutton produces less low frequency rumble, but it also takes from a lot of the energy in the music resulting in an emotionally “flat” sound. Pro-Ject lists the filter as 20Hz with a slope of 18dB/octave however, the “20Hz” part confuses me because the filter doesn’t sound like it starts to drop at 20Hz. In fact, it sounds like it drops off at around 30-35Hz. It's superb balance of attitude and refinement. If the rest of your system is up to scratch, the MX-VYNL is worth the investment.

Entry-level products like the Schiit Audio Mani 2, Cambridge Audio Alva Duo, and U-Turn Audio Pluto did their best to not rob music of its pace and keep the sound relatively balanced.

The Dark Side Of The Moon

In addition, the midband voltage gain of the input stage is adjusted at around 46dB. With that kind of a low input level, it is apparent that low noise transistors (such as the BC109C) are required to get excellent performance.

Please suggest me a good quality stereo audio small signal preamplifier circuit which can work from 5 or 6 volts single supply, that would not load the set top box, preferably using good low noise op-amp with detailed circuit and parts label. Sound quality is first-rate: fantastically detailed, with the upper register particularly impressive. It’s difficult to imagine a more detailed presentation from a phono stage for the money. There are rivals with an equally wide soundstage, but they perhaps don’t shine the spotlight so intensely on each instrumental strand. Detail is where it stands out, but the Gram Amp 2 is also a dab hand at dynamics and timing – although perhaps not with as much bite and punch compared with the Rega. On a car stereo head, which has 4 (line-level) outputs for an amp (FL, FR, RL, RR), I am trying to get another stereo pair, to go into another stereo amp for a third pair of speakers. I am concerned that if I simply take one of the stereo pairs and use passive Y-connectors to get the new pair, each will be quieter, because the power would be shared across two.

The analog output is a buffer that is both solid state and high-quality tube. Thus, the customer can choose which of the option is preferred. The Pre Box has eight digital filters. One of them is the proprietary optimal transient digital filter from the MQA creators. With these filters, the listener can customize the sound to suit their own preferences. Pre Box RS2 Digital comes with full HW and SW support for MQA technology (Master Quality Authenticated). Any music as we know is in the form of a consistently varying frequency, therefore when such a varying input is applied across the indicated C1 end terminals, the same is delivered across the base T1 and ground.

If Freddie’s trumpet playing doesn’t have a palpable feel to it, you’re only getting part of the experience. The Croft excels at that in the right system. Phono preamps come in all shapes and sizes – consumers have never had as much choice as they do in 2022 regardless of budget and the availability of so many great options will only help keep new users in the fold. It is recommended that the voltage gain should be kept within the limits stated earlier. C2 rolls of the high frequency response of the amplifier, and is necessary as instability might otherwise occur. I am not a total audiophile who demands ultra-low noise and distortion, but I would be wishing for this buffer to be more-or-less ‘transparent’. These usually provide an output signal level of about 0.2mV. R.M.S., which is about one tenth of that generated by a high impedance microphone.So why do you need one? Your stereo amplifier or turntable may not have one, in which case you won't be able to play records without this crucial component. Or you might just want to upgrade its sound beyond what's possible with the built-in phono stage found in amplifiers or some record players. Squeeze every inch of detail from your record collection with our highest quality moving magnet and moving coil phono stage, with integrated headphone amp; the Duo Phono Preamplifier. The circuit described so far, are of course, only suitable for use with high impedance microphones, and provides insufficient gain for use with low impedance types. Applying even the highly sensitive measuring devices at our fingertips we still could not determine virtually any output noise signal whatsoever! The required value of Rf is found by multiplying the required voltage gain by 560. Thus, a voltage gain of ten limes, for example, requires Rf to have a value of 5.6k.

The circuit is self explanatory, and can be integrated with any standard power amp for further amplification. Guitar Preamplifier Rather than use a series of dipswitches (as many rivals do), the MX-VYNL has a rather elegant control dial to manage the switch between moving coil and moving magnet inputs and their different loading requirements. Sound quality is seriously talented and it comes bursting with texture and insight. It's a wonderfully clean and crisp sound, with more low-end weight and substance sitting alongside Cyrus’s traditional values of precision and speed. If you’re in the market for a quality affordable phono stage, this little Award-winning box is well worth auditioning.The matching amplifier introduced in this article answers these difficulties: it features a high- impedance (1M) input that will stand up to voltages of over 200 V. The output impedance is fairly small. Amplication is X2 (6 dB). Yes, there is also this possibility. You can buy a turntable with an integrated preamp. However, this decision only makes sense in a few cases. For example, if you only want to listen to a record occasionally or digitize old records, a turntable with a preamplifier can be a good idea. After all, this can then be easily connected to an amplifier and used directly, this also applies to the PC or the sound card. If you want to listen to a turntable for music and also the appropriate quality, then a turntable without an integrated preamplifier is the better choice. In this way, you have significantly more control over the individual components of your system and can easily retrofit or replace as required.
