Re: Uli Behringer of The Music Group Q&ADear JR,thank you for your comment.In the ADA8000 the opamps are all designed around low-impedance circuitry and hence interchanging the TL072's with NJM4580's is not an issue.The TL072 has an operating current of around 2.5mA while the 4580 draws approx. 3 times as much. Due to the vast amount of opamps used in the ADA8000, the TL072 was chosen to reduce the overall power consumption and the subsequent heat dissipation of the linear power supply.The new ADA8200 uses a switch mode power supply which features a much higher efficiency and hence heat is no longer an issue. Due to this reason we implemented the 4580's for better overall audio performance.
