T he fact that the guys at Heed Audio know their business should now be obvious to the readers of image hi-fi , at least since our review of the Orbit psu (6/2000): a Rega Planar 3 equipped with this device took pricier record decks virtually by storm, and what is more, without putting insur- mountable financial hurdles in the way of vinyl lovers. More prosaically: this analogue per- formance-enhancing drug is bloody cheap in comparison with rival products, not least those selling in huge quantities. The Hungarian manufactu- rer saw an even bigger challenge in designing a reasonably priced phono stage. “The signal processing of car- tridges ist one of the most deli- cate jobs in amplification”, says Alpár Huszti, spokesman of Heed Audio, all the more so because it isn’t done merely by boosting a few hundred micro- volts to a few hundred millivolts. The 60 dB necessary for that – a thousandfold amplification in fact – also gives rise to huge noise problems. What is more, it is not a relatively simple linear but a frequency-related amplification job. It is well known that an equalisation curve is applied in the cutting of LPs, whereas a boost of around 20 dB in bass response is necessary when the disk is actually played. No wonder the range of first-class phono stages is fairly easy to survey. Before proceeding to the question of whether the arrival of this Heed component has changed the face of the phono stage market, let’s make one thing clear: at the moment, you can’t get more phono stage for less. The Quasar is a two-box design with separate cases for the power supply unit and the actual amplification circuits, which are not based around the ICs used by everybody else at this price-level, but built as a discrete design in the best audiophile traditions. It also means that it is built in dual- mono configuration from the power supply upwards, including separate earthing throughout! The Quasar works both with MM (the fairly high capacity of 470 pF did not bother my Linn K9 at all) and MC cartridges of all kinds due to its three different settings for sensitivity (100, 220 and 600 microvolts) and load (100, 220 and 470 ohms). The various settings can be applied by jumpers on the PCB, and can be freely combined. The Quasar is equally armed for all eventualities at its output end: pre-amps can be fed via its “Low Out”, whilst its much louder “High Out” can drive power amps directly. If you have a look inside the psu, you will immediately realize what the Hungarians mean by “battery-like” power supply. The unit is constructed around a massive 60 VA toroidal trans- former with low-density magnetic field and minimal dispersion, as well as 2 capacitors per channel with a 40,000 μF filtering capaci- ty in total. These capacitors, in order to reduce internal resistance and ESR (Equivalent Series Resistance) to a minimum, are connected in parallel. A word about optics and build quality. Of course, more ‘lifestyle’-oriented components can be found elsewhere, but this unpretentious Hungaro-duo has a solid heavy-metal charm throughout. Finish is, both elec- tronically and mechanically, first class. No screech, no rattles, and the only thing you might wish for is a removable power cable – not for hooking up some idiot-wire, of course, but to provide a bit more flexibility in its placement. Such trivialities are gone with the wind when the Quasar starts to play music. The thing is incredibly fast, its fine dynamics are more nimble, and its rhythm is crisper than anything on this side of £800.

The fact that the guys atHeed Audio know theirbusiness should now be

obvious to the readers of imagehi-fi, at least since our review ofthe Orbit psu (6/2000): a RegaPlanar 3 equipped with thisdevice took pricier record decksvirtually by storm, and what ismore, without putting insur-mountable financial hurdles inthe way of vinyl lovers. Moreprosaically: this analogue per-formance-enhancing drug isbloody cheap in comparison withrival products, not least thoseselling in huge quantities.

The Hungarian manufactu-rer saw an even bigger challengein designing a reasonably pricedphono stage.

“The signal processing of car-tridges ist one of the most deli-cate jobs in amplification”, saysAlpár Huszti, spokesman ofHeed Audio, all the more sobecause it isn’t done merely byboosting a few hundred micro-volts to a few hundred millivolts.The 60 dB necessary for that – athousandfold amplification infact – also gives rise to huge noiseproblems. What is more, it is nota relatively simple linear but afrequency-related amplificationjob. It is well known that anequalisation curve is applied inthe cutting of LPs, whereas aboost of around 20 dB in bassresponse is necessary when thedisk is actually played. Nowonder the range of first-class

phono stages is fairly easy tosurvey. Before proceeding to thequestion of whether the arrival ofthis Heed component haschanged the face of the phonostage market, let’s make onething clear: at the moment, youcan’t get more phono stage forless.

The Quasar is a two-boxdesign with separate cases for thepower supply unit and the actualamplification circuits, which arenot based around the ICs used byeverybody else at this price-level,but built as a discrete design inthe best audiophile traditions. Italso means that it is built in dual-mono configuration from thepower supply upwards, includingseparate earthing throughout!

The Quasar works both withMM (the fairly high capacity of470 pF did not bother my LinnK9 at all) and MC cartridges ofall kinds due to its three differentsettings for sensitivity (100, 220and 600 microvolts) and load(100, 220 and 470 ohms). Thevarious settings can be appliedby jumpers on the PCB, and canbe freely combined.

The Quasar is equally armedfor all eventualities at its outputend: pre-amps can be fed via its“Low Out”, whilst its muchlouder “High Out” can drivepower amps directly.

If you have a look inside thepsu, you will immediately realizewhat the Hungarians mean by“battery-like” power supply. Theunit is constructed around amassive 60 VA toroidal trans-former with low-density magneticfield and minimal dispersion, aswell as 2 capacitors per channelwith a 40,000 µF filtering capaci-ty in total.

A word about optics and buildquality. Of course, more‘lifestyle’-oriented componentscan be found elsewhere, but thisunpretentious Hungaro-duo has asolid heavy-metal charmthroughout. Finish is, both elec-tronically and mechanically, firstclass. No screech, no rattles, and

the only thing you might wish foris a removable power cable – notfor hooking up some idiot-wire,of course, but to provide a bitmore flexibility in its placement.

Such trivialities are gone withthe wind when the Quasar startsto play music. The thing isincredibly fast, its fine dynamicsare more nimble, and its rhythmis crisper than anything on thisside of £800.
