I am looking at purchasing a CD transporter which I believe does the same function as my Macbook CD/DVD player fed via USB onto Musical Fidelity VLink192. A/B comp between playing Apple Lossless music file from iTunes and from Macbook CD/DVD player, the latter sounds a tad better. This lead me to the idea of trying a CD transporter+my Arcam IrDAC setup. Anybody had an A/B comp experience between the two setup?
