Which dac or other suggestions


First time poster here. I am looking for advice to increase the sound quality of my existing system. I have a Marantz SR7009 being used as a pre-amp powered by Emotiva's XPA-5, 2 revel m22 bookshelf speakers serving as my L & R, revel c52 center speakers and 2 revel timber matched C563 in ceiling rear surrounds. I mainly listen to music and switch between L &R stereo only and sometimes "all stereo" or matrix through all speakers. We do watch movies but seem happy with our home theater experience thus far although always open to suggestions. We mostly listen to music through a Sonos connect but we also do have an Orbit turntable. I know that the turntable will one day need to be upgraded to maybe a Rega RP3 or similar. I am in the process of adding two SVS SB12-nsd subs to the mix. Our room is large at 20x30x10 and I hope these subs will make some sort of impact. We also use an Apple TV. Now for my question.

I am looking to increase the sound quality of my Sonos driven music. I spoke to an audiophile (owner of Echo audio in Seattle) and he suggested a dac. In particular, because he knows I'm cheap haha!, he suggested the California Labs Sigma ii, Enlightened Audio Designs DSP-7000 mkiii, and some Krell dacs (stealth and ??) that I have never seen listed for sale. I missed an opportunity on both the Cal Labs and the EAD and I'm kicking myself. With ALL this being said, what other dacs should I consider? My budget is $750 or less and I would prefer $400 or less. Old vs new? Tube? NOS? DSD? Yadda yadda. I am looking for an increased sound stage and dynamic range. If I get more clarity and warmth then yee haw!

I appreciate all of your input in advance. Thanks for letting this first timer ramble.

Btw, I listen to mostly indie rock but I seriously dive into ALL types of music and yes I like it loud.

I'm reading favorable things regarding the Blue Sound Node 2. In fact, even my dealer recommends it. Claims he sells it to folks buying 20K+ systems. He didn't say, however, whether or not those folks are using it as transport or the total source (i.e. it's own DAC and analog out right to the amp). I'm on the fence with it but will probably pull the trigger at some point given its relatively low cost. If the USB were plug-and-play it would be a no brainer and I'd jump on it immediately. I don't like the fact that I'd need software on my computer to deal with selecting the playlist, but I may have to swallow that pill. 

Are you using the Node 2 as transport or using its internal DAC?
@gdhal - re ....

Question for you (or others on thread).... I have an Oppo UDP-205. I’m very happy with the sound. So too are many others. That said, have you or anyone else on the thread had a chance to hear the Oppo and if so, how would you compare the sound to the Node 2? I’m only interested in sound comparison. Features are besides the point. They likely sound different because Oppo uses Sabre ESS DAC and I believe Node 2 uses Burr Brown.

You are correct - the Node2 apparantly uses the  Burr Brown PCM5122

Unfortunately I have no knowledge of the Oppo - other than they are very well respected in audio circles according to many of the posts I have read.

Personally - I found removing the computer completely from the path...
- improved the sound quality - no more USB related issues
- made life so much more simpler - no more OS/SOftware upgrade related issues - their is only one update source and that is from Bluesound - before I had MAC OS, iTunes and Audirva updates that had to allign - just like the stars some days :-)

I've found that even with Bluesound,  I prefer the interface of the App on my computer to create playlists - just because for me, the interface seems the easier place to perform that specific function

Hope that helps

I have found more differences between lower priced dac's than higher priced dac's. 

In terms of the higher priced dac's you pay more for that last 5-10%, but generally they all sound very good above $2,000.

With sub $1000 dac's I've found a wide margin of difference. Some cannot resolve enough detail, some cannot produce a wide or deep soundstage. Some can.

Choose wisely.


The Gustard X20 Pro with Singer SU-1 sounded as good as a $2000 previous generation Benchmark DAC 2 to me. That would be my budget recommendation. 
A few months ago, I replaced my Teac UD-501 with a Gustard x20Pro/Singxer SU-1 combo.

It was a huge leap in sonic performance. I've since cleaned up the SU-1s' power supply by installing the 4.5V SBooster Ultra board between the internal power supply and Singer main board.
