I'd bet it's some kind of vacuum device. Single ended for a more natural, wide, relaxed, eh...... uh......lightstage.

The DAC/Pre amp with IR reciver, motorized pot controlling a Lightspeed Attenuator and channel selector/mute on the left knob using a rotary encoder. All controlled by a PIC16F690 microprocessor.

If you are refering to the area around the lettering on the ic, I think it is a shadow and some stray thermal compound.....hopefully.

Hi tempted,

Those speakers are my DIY 'Derwent' cabinet speakers using CSS EL70 drivers. Here is a link to the 'Full range speaker gallery' as them:

http://www.diyaudio.com/forums/full-...ml#post3152149

The plans for the speakers can be found here, the speaker cabinet can be found by downloading the 'Lake District Series' pdf.

Frugal-phile | Box Library / CSS

They are great sounding speakers, and the bass that can be produced is incredible from such a small driver. Although they are full range, I did think the very top end was lacking a little, so I built some super tweeters using Dayton drivers:

See post #97
