I am excited by the idea of this much quality, in a small package, for just £1400.

But you need two, no?

No, you can run a single unit in mono.

To be fair to Lindsayt, he has (I think) heard the Phantoms at the Scalford show.

That's not really an option for a main system I guess? (Thats also for the lower powered ones)

Still, would love to hear a pair!

Thank you Chebby. I'll accept your apology.

I've heard the Phantoms at Scalford and in my own home now.

If you're listening to them in mono, then the stereo soundstage is non existant. That flaw alone would make it extremely difficult for them to be competitive with any competent £30k system for stereo recordings.

And Chebby, too much of what you've written in this thread is in response to stuff I've written elsewhere. If you'd like to respond to anything I've written, can you please do it on the thread where I've actually written it. If you'd like a genereal discussion on my approach to hi-fi then please start a new thread.

I am not going to comment on your off topic remarks here in this thread.

With the Phantoms, by lifestyle I mean that they are small and look unusual in a fashionable way. They are also all in one solutions. Those factors have taken priority over ultimate sound quality. Either that or Devialet are incompetent when it comes to achieving sound quality. I very much doubt it's the latter.

So the Phantoms are a good solution for someone looking for a small, convenient, portable, trendy looking sound system that is willing to put up with their compromises in sound quality.

Clicky.

Aren't these $2K? Why are they suposed to outperform a $30K system? I must have missed that part of the thread. *unknw*

Again, unless I'm wrong, thats for a single unit (for the lower powered one?). Pretty much useless in a stereo set-up so you have to double that.

Yeah. But still it's $4K against $30K.

Phantom's White Paper claims:

The Heart Bass Implosion® principle: Electro-acoustics miniaturisation

| 16Hz to 25kHz bandwidth, ± 2dB

| 20Hz to 20kHz bandwidth, ± 0.5dB

| 105dB maximum SPL*

*The legal limit in clubs and live concerts.

Any $30K systems that outperform them at least on paper?

Are those figures for the lower powered ($4k) pair of phantoms?

I presume the basic model since no model number is disclosed.

The figures are for the Silver (more expensive) Phantom. The basic model tops out at 99dB.

Indeed. I just had a look at Stone Audio which confirms that.

Power is quoted as 750 peak ... whatever that means. Bearing in mind you can buy £200 cinema all-in-one systems that quote 1000w peak ... . I also can't see any distortion figures but that may be an oversight of mine.

So, the more expensive Phantom/s suddenly become a rather costly proposition and although I have no doubt it is an immensly impressive system I for one take the figures with a pinch of salt.

Still, without hearing them it would be foolish to judge them on anything other than whats on paper and price.

The State of the Art before PHANTOM: Very large loudspeakers

Big sound needs big loudspeakers. This has been true for a hundred years, since the invention of electrodynamic loudspeakers.

The most commonly used speaker acoustic loading principles are bass-reflex (also called vented) designs, and sealed box designs.

Vented designs suffer from energy cancellation at the lowest frequencies, below their resonance frequency - it is called the acoustic short-circuit. Except for very large speakers, the scale often lacks scale and impact since the frequencies between 16Hz and 50Hz are not reproduced.

Sealed box design are more desirable when it comes to being able to reproduce very deep bass without losing energy because of the acoustic short-circuit. But again, very large speakers are needed in order to reproduce every music with its entire physical impact.

Typically, the high-end loudspeakers that can reproduce most of the audible spectrum inside a home have a very large internal acoustic volume of 100L to 200L! This is as big as a bath tub. Most people do not want to, or simply are not able to, fit this into their home.

(from the White Paper)

BTW my old Sony speakers are infinite baffle 68L boxes and reproduce in the 27Hz-25kHz range. The AR-11Bs I had were under 50L IBs and also went down to 27Hz. This 120L for 30Hz claim seems a bit shoehorned. But still the Phantoms are an impressive engineering achievement spec wise.

There is to be a software update out very shortly which will alow the Phantoms to be used with tablets and phones. Hopefully by next year they will be as easy to use as a Sonos system. They have a much higher sound quality and can play high bit rate music.

If the Bluetooth works as expected, I intend to buy a pair and start upgrading from Sonos (which I have enjoyed for may years). I currently use a Spendor floorstanders powered by an Arcam amplifier (using Sonos and NAS as my source), I am pretty old and conservative, but was blown away by the sound of the Phantoms. Don't be put off by their appearence, just try listening to them.
