This's my second system now, but the main for long time until I recently assembled the new one with great used components like Thiel and so on.

You can see DIY modification on Adamantes loudspeker, I improved the acoustic performance of the cabinets applying internally some lead sheets glued with polymer MS to ensure a perfect coupling in order to lower the resonance frequency: the result is amazing! Noticeable improvement  for bass extension and control.

Also the DAC is DIY based on modified ECHO AUDIOFIRE 4 board  and connected to the MacBook via Firewire.

I continue to enjoy a lot the performance of this old setup, very clear and amazing sound specially thinking to the loudspeakers size, for sure a good match with the Sugden A class amplifier, few but very good watts indeed.
