After murdering the headband for 3 weeks, it's now staying loose finally. Fazors just barely touch sometimes. Did some more tests with the Hifiman spacers, can't say I notice any difference at all, so going to keep them in. Also bought some vegan pads and they don't touch with those. Thought I'd measure the impedance of my 271/LCD3, it is 107 ohms.
I am finding them very easy to listen to I must say. Very sweet sound that I can listen to all day (unlike my HE400). At first they were very uncomfortable but I got used to the weight now. The soft squishy pads help a lot, they could do with some more padding in the headband though. I thought the HE400 had some kickass bass but these are on another planet, they really hit hard and deep. I think the treble is just right, any more and it would be a touch too bright. The mids and vocals are perfect.
I much prefer the LCD3 to the LCDX. I had the pleasure of comparing the 261/LCD3 on an Auralic stack to the HD800 balanced on a Cavalli LAu/Calyx Femto DAC. On that setup, the HD800 was just as good, however, every other setup I have heard the HD800 on including Auralic stack, HDV800, Conductor, it doesn't even come close for me.
