Best DAC for my system?


Thinking I would like to add an outboard DAC to my system.  I have Forte IIIs, McIntosh MC2105, McIntosh MX119 and I use a Bluesound Node2 for streaming.  What would be best options in the $500 range?  Or do I need to spend more on the DAC to make enough improvement over the Node2 DAC?  Thanks....

crn3371..yes I compared them and the Node 2 sounds better.  The MX119 was a little dull and not as defined.  Thanks for the suggestion though.

Talk to Tommy at the Digital Amplifier Company (DAC) the DAC DAC HS is exceptional. Contact him for a price he always has demos available.

Seems you have about 7.5k to 8k invested in your system so far... You owe it to your self to upgrade your source, streamer/dac... 2k to 2.5k seems about the right balance with your current kit... Benchmark and Chord are good suggestions... You might also look at Lumin... And some room tuning/treatment would not be a bad idea at this point if you have not already done so...
Kick the node and go straight to a Lumin D2 streaming DAC.
$1600 to $1800 used but your ears will thank you immensely.
Pro- Ject Pre Box S2 is  $400 at Music Direct with a 60 trial period. If you use Tidal it will do MQA if that matters to you.
