Bottom Line:   
I have bought Helicon 400 for replacing Jamo D590. I have had also the opportunity to coddle Helicon 800 by 1 month.

First of all some data – my listening room is almost 50 m2 (400 feet), really good muffled. CDP and amplifier – Audio Analogue, Harmonic Tech cables (Truth Link and Pro-9). Granite rack 90 kg. I listen to all kind of music.

Build: Helicons 400 are extremely beautiful loudspeakers. My first impression was even they are too beautiful – high gloss. Now everything fits well. Red walnut wood reminds precious cello or double bass and this is it. Helicons are really heavy – 32 kg. For stable placing it is recommended using included spikes. Drivers from Peerless and Vifa (?) gives quality guarantee. Woofer-midrange brown cones are made from paper with wooden fibers. Terminals look very noble. Everything in Helicons fits their upper class status.

Sound: These speakers have no week points. Somebody can say they have their own character – that’s of course the truth. But nothing lay below par – be sure.
The sound in general is very even and smooth. Any part of the frequency range is not up the front. Midrange is very informative, gives a lot of details but priority is somewhere else. Real sound colors, harmony, musical pleasure – that’s the first. Guitar sounds are flexible, melody is presented with incredible easiness. Female vocals are light and do not contain any undesired coloration. Yes, midrange is unexceptional beautiful. High frequencies drivers are not typical – silky tweeter and ribbon tweeter co-operate together. Can be to much brightness? Never! The high frequencies are superb and it is one of undoubted advantages in Helicons 400. Cymbals, triangle, any high voices bring a lot of pleasure. Nothing is 'by numbers'. All subtle sound differences in this range are easy to recognizing. What about bass? I enjoy my Helicon 400 in relatively big room and no problem with bass fundament. Placing in the right position can give you what you prefer – more or less bass. I prefer not too much low frequency sounds so my Helicons stay 1m from the back wall and about 1.5 m from side walls. It gives pretty good, well defined bass and even with the rest of the scale. Lowest frequencies are extended really low – 32 Hz for -3 dB is a really great number. And they are really fast!
Helicons give a lot of details so it means also they show in great manner all subtle echoes, the recording studio reverberations and going out sounds. The result is very obvious – soundstage is present always and gives really great imagination of the space around the music. The sound sources are pretty good defined however their size it is not a needle head. And it is good. Surgery can kill the music :- ) 3D impression is full and the spread of the stage is as well horizontal as vertical. Helicons do that well.

What about electronic stuff? Helicons are not fussy. They can play with any sort of amplifiers, never hurt your ears. I tried them with pure class A Logos Pathos (valves) and sound was simply great. Bass became more round and warm but the listening pleasure remainds the same. Also Roksan Caspian brings Helicons to live, special in rock music. Bass gets better definition and top of the range still keeps far from brightness (Caspian can be too bright for some speakers). In general – stronger source is welcome.

Competitors: Before purchase I have had opportunity to hear Audio Physic Virgo III and Triangle Naia. Both belong to the same price range. Virgo III is very precise in details and soundstage but misses musicality. This is something for music analytics, not for music lovers. If something can really impress in Virgo III it is their bass. It is not so heavy and extended as in Helicon but light and précised. It seems also fast what is typical for light weight fighter. Unfortunatelly, classical music, big orchestra - it is not for Virgo III. Gathering together all what you can hear requires your brain effort. Can you accept hard work when you are looking for pleasure? Triangle Naia impress with their dynamic presentation but they are also not natural, not at all. Their artificial sound fits maybe to electronic music where everything is artificial. Both classical or jazz sound strange. Good if you are tired with real, true music. Triangle Naia exaggerate.

Summary: Helicon 400 are great loudspeakers. They put music before cutting of the borders. They keep everything in hands. Pleasure is the priority. Easy to drive, dynamic, open sounding. Maybe not the best efficiency but my amplifier has got volume knob if necessary ;-)

Margin note: Someone can ask is it worth to add some money and buy big brother - Helicon 800? It is a good question. Despite nobler look Helicon 800 sounds different. The main feature is the same – music first. But the 800 manner is more impressive. Sound contains a bit more stage character even if the music has been recorded in the studio. Vocals shine with smell of metal glossy which also gives better ‘concert impression’. General their sound is still very even but their midrange stress lays an inch lower than in 400. Helicon 800 plays a bit more lower midrange and their sound contains so nice for my ears body, musical meat. Also the following of the bass walking is easier on 800 than on 400. Please, understand me well – nothing wrong with 400, just the difference. If you can effort Helicon 800 I strongly recommend them. You can hear the difference in your pocket.

Bottom Line:   
These speakers spanked the hell out my B&W Nautilus 804s. I had to give up the 804s because the highs often seemed harsh and although they sounded great in the store, they were hard too live with and started annoying me after listening to them for awhile. Eva Cassidy's normally sweet voice started screaching with the B&Ws and would occasionally have me saying ouch. In comparioson, the Dali Helicon 400s have a much more open double tweeter (exceptional soft dome and ribbon combination that should beat the tar out of the B&W Diamonds) that are warm and detailed with a wide sense of spatiality and imaging and are not harsh and overly focused like the B&Ws can be. By my ears, the Dali Helicons are some of the best speakers out there in the high end audiophile range period.

As a side note, although I have not heard them side by side, for the price the only other speaker that may give them a good run for the money is the Onix Reference 3s. With high excursion 7 inch subwoofers and a similar double tweeter arrangement, the Onix Ref 3s should be good competition. Onix would probably sell alot more speakers if they would figure the average cost of returns into their retail price so people don't have to risk a full $400 demo fee to pay the round trip shipping. Note you can deal Onix (at AV123.com) down by hundreds on the price they show on the internet by calling and talking to them!

I am keeping my Helicon 400s as I can't imagine a much better speaker except for the Helicon 800s - but with a subwoofer, the 400s should sound roughly equal the 800s in sound. The sound from these babies is exquisite. The highs are open and detailed without being harsh. The bass representation is tight, accurate, and full. They sound fine without a sub, but because the two midwoofers in each speaker are only 6 1/2 inches diameter, a person who wants a very full and deep bass extention would probably like a musical sub to augment the bass. But make no mistake, the bass without a sub on these speakers is great. On that note, Onix makes a very musical sub available for around $500 that works well with these speakers. The Helicon Sub is almost as much as the speakers, so you may want to look at the Dali SWA 8 or 12 . However, by my own experience the Onix Rocket UFW-10 may be the most musical for the money and works great with these speakers.

I have the Rosenut color which is best by my taste. The fit and finish is top notch. They come with real wood veneer with a piano gloss finsih. They can be found at discount also with a little internet surfing or local dealing. Some sellers on the internet go as low as $3,250 new per pair without a warranty (ask!)

I recommend at least 125 watts of power for these speakers. I had a Denon AVR amp that advertised 135 watts per channel and the bass sounded grainy and distorted using it to drive the Helicons. However, the Helicons turned into different speakers when I powered them with a much lower priced $250 Harman Kardon 3480 two channel amp that rates itself at 120 Watts per channel! Apparently, the Harman Kardon's higher current watts are underated as much as the Denons are overated. I myself ended up driving these speakers with a 200 Watt Rotel RB-1080 but a 120 Watt Rotel or HK should do the job well. I would stay away from driving these speakers with a Denon unless it advertised at least 150 Watts per channel.

For my personal taste, I run my CD player through an equalizer where I advance the bass and midrange a few decibals and reduce the treble by one decibal from flat. For most people, the bass and treble knob will more than suffice as this adjustment is not major. The sound great without an EQ or bass/treble adjustment.
