Do I need a DAC?


Hello,

My setup is the following:

Airpot Express >> NAD C326BEE (amp) >> B&W DM685 (speakers).

My question is, if the sound quality would be significantly improved by adding a DAC to connect my Airport Express with my amplifier? I enjoy listening to music, but I am not obsessed by getting the most clean sound etc.

How is your opinion on this?

Thank you in advance!

He didn't say he was obsessed with bad sound.

Actually, I think I can see why the OP was worded the way it was. I've read threads on this site were people would argue like its life and death over things like what kind of rca connector is best on a pair of IC's.
Whether you'd get appreciably better sound quality from an external DAC depends a lot on the source material too.

Are you playing hi res files, CD rips or just 128kbps iTunes downloads?
Thank you for all the responses!

B_limo: I never said I didn't care about the sound - I simply said that I am not OBSESSED by having the best of the best. Big difference.

I am mostly playing 265kbps or higher from iTunes, but not 24-bit and so.

Keep the responses coming guys :)
Oscarrr, you don't need to be playing 24 bit files to be able to appreciate a better DAC. Most of my files are standard 16/44 and I find an external DAC necessary for the low cost sources that I use.
Oscarr, you have a great entry level system in the making. The express represents the weak link. A DAC would serve as an upgrade. The PS audio digital link III is often found used on this site for ~$350. Good DAC at that price, especially when avoiding the USB input. I play 44.1/16 bit files ripped from CDs.
The express outputs SPDIF?
