Hey Ash

Yes with the K1000 wings, I can easily understand how they place the soundstage around you. My oh my, you are selling those? Have you found different phones you like better? My LCDs are traditional open backed planar magnetics - with membranes focusing sound directly into your ears though. I am not getting any obvious out of phase issues at all. Everything is present and correct. If anything I am getting fatter and deeper bass, more weight and spatiality. Hence the puzzle. Which may not actually be a puzzle. Then again...

I got out to Maplin today and will solder up the parts tonight. If my rig works like you described I listen a bit and then send you it to try next Dil.

I used a 47R preset resistor in the earth/return line the left and right transducer share as their - terminal. The variation allowed me to try me some options with resistor value/preset settings. The sound on minimum resistance is pretty close to plugging the LCD's jack plug straight into the socket of the extension lead I use. At 47R (close to the headphones' impedance) it is a thin (little bass) sound verging on the single channel out of phase sound I wrote about above.

The sound got more interesting in the bottom quarter of the preset around 10 ohms where the headphones were quite full sounding but wider. The effect is pretty much that of the stereo width expanders that used to appear on graphic equalisers (Wicker Man moment!) and had a noticable effect on some mixes. Worth a little more listening before I send it onto Dillon!

Yeah, I recently bought another second K1000 as a listening reference. Both the ones I have sound really excellent (I can barely fault them - true studio monitor response, to be honest) but I have speaker drivers that I will be able to get sounding just as fantastic, if not more so. So keeping the two expensive K1000s doesn't make much sense financially; mentally, they've given me a high expectations of speaker sound and more of an idea what to aim for with tweaking speakers. I don't personally believe that there is a better overall headphone than the K1000s I've already used. MySphere 3.1 is too expensive for what it is (it's also positioned closer to the ears) and frankly, I'm just not interested in headphones anymore. For me, earpad headphones don't cut it for primary listening - too spatially constricted. I've already compared the K1000 against the HD800 with a sensible brain instead of "golden ears" and preferred the K1000. Not bothering trying electrostatics either; too expensive for me and they will most certainly compromise something sonically too. All technologies have their own set of compromises. I now believe that my highest enjoyment of my music will be from speakers like my MA 10P and 12P. Neutral transparent sound with very high resolution - they don't need to be perfect for me to thoroughly enjoy using them.

Apologies for cross weaving the earlier theme but I have just been listening to the 'can opener' adaptor and it has widened the image. Sounds panned hard left and right in mixes seem to be outside the headphones. I know this is because the some of the signal is also appearing out of phase on the other transducer but it is quite fun to listen to. Like Dil wrote earlier some backing vocals and other instruments are pushed outside their normal position.

As you'd expect there is centre cancellation so main vocals, bass parts and other centrally positioned sound drop in volume slightly but are still quite audible in headphones. For a fiver of parts from the high street it is an interesting sound option.

I have had another listen to the 'Can Opener'and am still enjoying the novelty of the wider sound stage. I will send you it Dil in the next week if I can.

Some 30 years or so ago the HiFi press reviewed a glossy black plastic project box bearing the words 'can opener'.

As far as I can gather it had attenuation circuitry (resistors) to drop the level from speaker level, and one "Hafler resistor" to obtain a wide effect. However, as headphone impedances range from 5 to 600 Ohms it would not be very effective on some/most.
