Should work out OK with the Velleman. The out of the pre is 220 and the input of the K8022 is 5K which is more than the min. 10:1 ratio usually stated for good performance. same with the in to out ratio (at all positions except in the max. attenuation)for the power amp. and K8022.
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
