Hi John – thanks for the reply. I’m always happy to hear from you no matter how long it takes especially since most of us want you to be busy building and not writing. I hope some of your customers can elaborate on the resistor vs autoformer sonics. I’m not sure if my assumption that the resistor unit will provide better low level details and the autoformer unit will provide better dynamics is valid.
I have a few other questions that you or someone else on this forum may be able to address.
My argument for a single dedicated input has always been twofold. First is to avoid the colorations of the selector switch contacts. Second is the sound of the chosen input is always affected negatively if you have another component connected to the preamp. Are these valid arguments for your single input units over your 6 input unit despite the obvious inconvenience of manually changing interconnects if you have more than one source.
Also your website states for the resistive based units the preamp to amp cable length must be kept VERY short for best performance. If the distance from my CD player to amp is 2 meters, why is it preferable to have a 1.5 meter cable from my CD player to preamp and a 0.5 meter cable from my preamp to amp instead of a 1 meter cable between the CD player to preamp and 1 meter cable from my preamp to amp? It also appears that you have a 6 inch cable from the Bent Unit, so an alternate arrangement might be a 2 meter cable from my CD player to the Bent Unit that is connected to my amp by the short 6 inch cable. If we take any cable differences out of the equation and assume them to be all the same as your short 6 inch cable is the alternate arrangement with a combined cable length of 2 meters plus 6 inches ever sonically superior?
