Mr S. Rouse, United States of America,

You truly have a standout product and the best speaker I have heard in 35 years as both a HiFi retailer and audiophile. S Rouse - USA

Mr A. Boys, London.

I tried them with my £25k system and the Duals were wonderfully engaging and played everything with great precision, truly the best I\'d heard, my previous Zingali HM212\'s weren\'t even close.With the completed upgrade of £16k of Tube amplification, £10k Tube Pre and £30k of Vinyl system, I have to say I am absolutely blown away, stunning! Mr A. Boys - London.


Mr S Brown (NZ)

The Duals are amazing – huge understatement!

I am running my Reimyo CDP777 directly into a Leben CS660P – using its own volume control, but no pre-amp.

Easily the most natural and realistic combination of components I have employed at home – probably ever heard. Fantastically realistic: great stuff!Mr S. Brown -Auckland NZ

When David came to take his speakers away I was very sorry to see them go, the EVO-1s are extremely revealing and engaging speakers that revel in a high quality signal.

This would not be such an issue in a larger and lighter room than mine but if there is any justice it’s the only thing that should stand between them and world domination!

You meet some interesting characters in the hi-fi fraternity and David Hart qualifies as one of them. How many people do you know that gave up a career as a barrister to follow their dream and build a no-holds barred loudspeaker? Perhaps that is why he spent four years coming up with a loudspeaker that incorporates some pretty radical thinking.

The Hart EVO-1 is a substantial speaker system that consists of two cabinets per channel, stacked one upon the other. One box contains eight bass drivers and is designed so that these drivers face the wall. The other cabinet features a 300mm dual concentric drive unit built around a Tannoy chassis. Hart has modified it and fitted a different magnet, so it’s no longer the same beast, but it’s an expensive piece of hardware nonetheless. On the back of this head unit box is an active amplification module, which drives the eight units in the bass cabinet.

These ‘bass’ drivers are only 115mm across, so are normally something that only makers of sound-docks would describe as a bass unit. But get enough of them together and stick a 500 watt amplifier on the end and they deliver bass that is faster, cleaner and deeper than pretty well any passive speaker on the market and quite a few active ones at that.

David calculates that these eight drivers are equivalent in area to a 330mm cone but the combined magnet power is equal to a 300mm magnet, something that would only work effectively on a 450mm driver.

The amplifier module looks like something from a sophisticated subwoofer, it has inputs for a high level signal and it has both XLR and RCA phono inputs for a low level signal such as is usually used in ‘point one’ systems. Hart recommends the high level route this way you have the same character of signal going to both halves of the speaker, and it also makes the amp module’s job easier. The amp module has controls for phase, frequency contour, high level and low level gain all of which have solid wood knobs to match the speaker’s finish.

The veneer on the sample I had was a superb book-matched walnut burr with beautiful figuring, Hart offers a number of stunning veneers which are laid up by a local company. Stainless cups for the rubber ball cabinet separators offset this finish. These balls started off as large bearings but have become very hard rubber spheres because of the damping that this approach affords. Remarkably these balls can survive the 62kg mass of the top cabinet and still retain their shape. They are also used between the bass cabinet and the 10mm steel plinth that forms a base for the system.

The bass system is designed to work into the corners of the room and use them as a crude horn, thus you need to angle the tower so that the eight drivers are firing in that general direction. I preferred the balance of the mid and treble with the speakers set square to the wall but that does undermine absolute extension or at least it seems that way. The quality of bass that this speaker delivers is so clean and articulate that you don’t get the same degree of room excitement as is normal, as if room modes are not being set off to the same extent as is usually the case with big speakers. It has phenomenal speed, which means that bass instruments come through with the subtlety and definition we associate with those pitched higher up the scale. This makes for awesome groove factor on anything with rhythm, be it Steely Dan’s ‘Bodhisattva’ or Mofro’sBlackwater.

I tried a variety of amplifiers with the Harts and each made its mark, not least the Digital Do Main B-1a with its VFET output stage. This radical Japanese amp loved the high sensitivity on offer and rewarded me with some of the finest and most atmospheric results encountered in a long time. John Abercrombie’s gentleWait Till You See HerECM album can sound a little bland with less revealing systems, but here both the tune and the presence of the musicians is placed front and centre. The realism is spine tingling, and this is not merely because of the bass system of course, that coaxial driver works phenomenally well as a mid/treble system despite its size. So well in fact that noise levels seem lower than usual This could be because of the sensitivity on offer but in many ways that should have the opposite effect and reveal any hash at the bottom of the amp’s output range, but with something as refined as the Digital Do Main that doesn’t seem to be the case.

Credit should also go to the Resolution Audio Opus 21 CD playing source; via the DDM and Hart the older and notably multibit player is the source of choice. After using the system for a while David Hart told me that at home he uses the boxes the other way around with the bass system on top and the base plate sitting on its front spikes only so that the main driver faces upwards. This he says works better for vinyl and I was going to give it a go until I discovered how hard it was to lift the main driver/amp pack cabinet.

Moving over to the Quad II Classic amplifier proved that despite the active bass drive the low frequency performance of the amp has a clear influence over this end of the spectrum. Now the bass was richer and softer but with plenty of energy if not so much power or snap. The overall result was attractively easy to enjoy but full of detail and, if not as sharp edged as the solid state alternative definitely more natural, double bass coming through in woody and timbrally rich form. The system also seemed to untangle the densest compositions and reveal the inner beauty of the music rather better, it had a more positive and optimistic view that brought out the message in the material rather effectively.

Moving over to my reference amp, the Gamut D200 MkIII brought back a high degree of analysis to the speaker, the way that a vocal has been treated is laid bare in a completely clean fashion. Often highly analytical systems can be a bit on the incisive side for my tastes but so long as the main drivers aren’t pointing straight at your ears this isn’t the case here. Of course if you want a sharper sound then the speaker can be set up to deliver it, likewise the bass can be adjusted to suit the room with the controls on the amp pack. The key ones are phase and roll-off both of which can be tuned quite easily, especially if there are two of you to do the job.

Back with the music Arab Strap’s vocal is almost laser cut because clarity and presence are so strong, then the drums come in and their reverb stretches way off into the distance. All of which makes for very powerful and engaging listening with material that’s as intense and intimate as that album provides.

Around this point in the proceedings I spent an evening listening to JBL’s new K2 horns at a friend’s house, he was raving about the detail coming out of these megabucks speakers and it wasn’t hard to hear why, however returning to the Harts and playing the same tracks resulted in a very similar level of detail with more powerful and substantial bass. Clearly the active element played a part here but there’s no getting away from the transparency on offer across the band.

Putting another amp into the mix, Chord’s compact Cyan Click revealed just how sensitive the speaker is. The Chord’s level indicator didn’t get out of the teens whereas with my B&W 802s some tracks warrant an output of twice that. By rolling the main driver off at around 70Hz and taking bass drive out of the equation, Hart has delivered a true high sensitivity speaker without the difficulties inherent with horn systems no wonder the Quad amp sounded so sweet.

When David came to take his speakers away I was very sorry to see them go, the EVO-1s are extremely revealing and engaging speakers that revel in a high quality signal. They are clearly more than worth the asking price even if the aesthetics are a little challenging. This would not be such an issue in a larger and lighter room than mine but if there is any justice it’s the only thing that should stand between them and world domination!

Review of the EVO1 Dual at the Heathrow Hi-Fidelity Show 2010

HART AUDIO

Hart Audio’s room was a real surprise and pleasure. I have not heard of Hart Audio speakers so I was new to the £15000 to £20000 Evo-1 \"Monitor\" \"Dual Monitor\" and \"Tri Monitor\" speaker series. At this point I think it worth while giving you the details from Hart Audio’s website, before talking about the sound in this room. These speakers are a two part design with what appears to be a stand actually being an intregal part of the design as this is an active bass module or ABM.

The designs incorporate the Dual Monitor for listening areas up to 300 cubic meters and the Tri-Monitor for listening rooms from 100-600 cubic meters. By reducing kinetic excitation by more than a third the EVO design allows a third more sound energy to be introduced to the listening area. By departing from conventional loudspeaker design the EVO-1 is a louder speaker with minimal distortion to the eardrum from kinetic interference providing a very clear and solid sound throughout the volume range.

This was one of the few rooms that really impressed me. At first look, my first thoughts were that these very large speakers would be too much for the room…well I was wrong. The sound was very open, detailed, fast, dynamic, with excellent clarity and musicality. It was also neither forward or dark but just right tonally and these speakers also had the ability to place a very real image in space that was very convincing. Now this image was perhaps not as pin point as that created by….say a smaller monitor speaker but it had the weight and scale that a smaller speaker would lack and thus the music had a more natural and realistic scale. Despite the use of one large drive unit and lots of small ones the music was articulate and coherent. This speaker in this room and on the end of the system was singing. Well done Hart Audio.

On the day I told the guy manning the room, that I thought they had about the second best sound at the show. It would seem that others agree with me as well.


London High Fidelity 2010(Hifi Wigwam Forum Review)

The surprisingly good


Hart Audio,I fully expected to hate these, not sure why. Maybe it\'s the ads


When I first walked in they were blasting out at ear splitting levels and I very nearly turned straight round and out the door. But glad I didn\'t because they where very impressive. But I would have liked to hear them at more normal volumes. So I popped back later and they were playing a very nice orchestral piece and they did it magically.


London High Fidelity 2010 (Art of Sound Forum Review)

Of the exhibitors (that I heard) who were able to demonstrate in their own room, I’ve saved the best for last:Hart Audio. Their speaker used a two-box construction. The HF and MF handled by a 12” driver in the upper enclosure with the LF being handled by an actively driven array of several, backward firing, 4.5” drive units. The speakers were powered by a valve amplifier using 6C33 valves (?), or similar. (The valves are the ones with the ‘nipples’ on top; valve experts will no doubt be able to tell us what these are.) Listening to ‘Cycles and Stories’ by Surindar Sandhu, this was a system I could quite happily live with and for me was the best of the show.

Barry
