The impedence values of your pre amp and amp are on the marginal side and much would depend on your cable choices and lengths. Have you thought about just putting it in the tape loop - that way the impedences values & gain would be taken out of the equasion. As a further benefit you can simply switch it out of the system by flipping a switch. I use a Creek in the tape loop of my ARC pre and it works just fine.
Passive Preamp Impedance Compatability Issues
I am looking to add remote-control volume capability to my audio system which includes a NAD 314 integrated amplifier. I've been told that a passive preamp connected between the pre and power sections of the 314 would be the best solution. I am considering the Creek OBH-10 and the Velleman K8022.
The Velleman (www.velleman.be) is substantially less expensive since it is a kit product, but I've never seen any reviews of its performance. My major concern with the K8022 is related to its impedance ratings input: 5Kohm, output: < 2.5Kohm. This is quite a bit lower than the preamp section of my NAD 314 input: 20Kohm, output: 220. The Creek has an impedance of input: <20Kohm, output: 0-20Kohm.
Can anyone tell me how these impedance figures would reflect on the compatibility between a passive preamp and my integrated amplifier?
Thanks, Jeff
