I live in a small town in Nebraska and need help. I have a Classe Sigma SSP MkII Preamp and a Classe Sigma Amp5. I just bought a Aurender A10. Since both have a DAC should I plug into the preamp or the amp and let the A10 use its DAC. I don't know if I stated the question correctly but please advise. Any help would be greatly appreciated. Thank you in advance.
