Audiotroy,You should email Coda to confirm, but the input impedance should be 10 kOhms for the balanced input and 50 kOhms for the unbalanced input. As the amp has a fully differential input stage with a DC-coupled balanced input, that would be the purest signal path. Going through the AC-coupled unbalanced input would route the signal through additional circuitry. Whether this is audible likely depends on your ears and your particular room/equipment and whether you have any ground loops. See: https://www.noiseengineering.us/blog/2017/5/12/ac-vs-dc-coupling-what-where-why ("Different types of voltage are handled differently at the input. DC-coupled inputs are the more straightforward: the circuitry just takes the input as it is. The entire signal passes through, more or less untouched. AC-coupled inputs are different. They include a capacitor in the circuit that allow them to filter out very low frequencies.") |
I do not post often as I come here mostly to learn, but having recently purchased a No. 8 amp (Version 1 for 18 watts of Class A bias 150/300/600 watts into 8/4/2 ohms) I thought I'd share my experience. To keep it short and to the point, it is the best amp I have ever owned. No matter the quality of recording or the volume I am listening at, I am constantly astonished. There seems no limit to it, even LOUD the meters barely register the deep bass plunges, and my B&W 702 S2s are notorious for wild impedance swings. I paid 6k for it, I would pay double for it and still feel like I got a smoking deal. Anyways, just my 2 cents. |
