I have had bass problems with the Transparent/Thiel como as well. While there seems to be no problem with the interconnects, there is definetly an interaction with the speaker cables! I own the Thiel CS6 speakers and now use MIT cables.
Where s the bass?
My system - Sony CD player, Pass Labs X0 preamp & X600 amps, Thiel 7.2 and Transparent Reference cables. I believe the sound is open, transparent, and dynamics. However I just wish I could put an emphasis on the bottom end. Tone controls are not available on high quality Class A preamps, such as the X0. While I understand that adding one more component in the signal paths is not desirable as it will further degrade the sound, I would like to hear your opinions on the best way to boost the bottom end. Thank you.
