I have modded and recabled my AKG K240 Sextett (mid-production).
I have been listening to it for about 2 months but didnt want to write before because I wanted to adapt to the sound and I was afraid of the "new toy syndrome".
Now its time to write something...
I have compared K240 Sextett (mid-production) to my Beyer DT150, Fidelio X2, AKG K7XX and Modded Fostex T50RP.
I can confidently say that I can sell them all, except the DT150 because I need a closed headphone with better bass.
Also K240 Sextett delivers the tiny details that other HP's were missing... It creates a special atmosphere around the instruments and micro-detailing is awesome. It sound very lienar too. Not bass heavy, not bass light.
I am in love
I feed the K240 Sextett through my Darkvoise TH336SE tube amp (Fitz modded and with military grade tubes).
