Yes a coaxial cable woks better but I have since added added to my system an iPod/Wadia 170i combo through the same DAC (A324) and its sounding very nice here now. The digital cable I used is the Creative Cable "Green Hornet".
Newer CDP vs Older DAC
Hello. I was wondering if it ever makes sense to use a newer CDP with an older DAC? Actually I just got rid of an Technics 110 disk player of which I used the optical out into a Musical Fidelity A324 DAC. A fantastic sounding combination. Both are about 9 years old. Again, I only sold the Technics. I then plugged the optical out of a Marantz CC4001 DCP changer purchased about a year ago, which supposedly has a very good quality DAC into the A324. To my ears a far worse combination. Not nearly as vibrant or realistic. The sound of the present combo is too laid back/recessed with boomy bass being the obvious disadvantages. Any opinions on this is appreciated.
