I have a Theta Pro Basic IIIA in my car along with Dynaudio speakers and Soundstream amps. I agree most car hi fi sounds poor. It wasn't until I started using separate DACs that my car system started to sound good. I was using Denon's best car audio stuff which can not hold a candle to my old SONY Walkman feeding a CAL Gamma DAC. I am currently using a SONY changer, Optichord Toslink to a Theta TLC. BNC-BNC DH Labs D-75 to a second Theta TLC and then to another DH Labs BNC-BNC cable to a Monarchy DIPMKII to the Theta Pro Basic IIIA. I am using a Radio Shack 140 Watt inverter with absolutely no hum. Cabling consists of Kimber PBJ, Cardas and Kimber 4TC to the Dynaudio three way system. Feel free to e-mail me if anyone has any questions about running separate DACs in the car.
