I started my setup with a Laptop that stored my ALAC and FLAC music collection, connected to a Klipsch Fives via Bluetooth, then i considered to add a DAC which i bought a ARES II since theres alot of reviews and rave about it, the sound coming out of my powered speakers changed immediately its like night and day that time i immediately knew that DACS work, immediately i was happy with my quite expensive purchase and later on added a pre-amp in to compliment the ARES II, which also further improved the quality of the sound, so in my humble opinion i can say that DACs can really contribute the quality of the sound output and can therefore can enjoy the music even more which is the main goal of all these craziness.
