The big DAC decision


One of the challenges of building an audio system is trying to make sure that all of the individual components of that system have equivalent and compatible technical specifications. For example, it doesn’t make sense to purchase speakers that are capable of producing sound in the 5Hz to 20kHz range if your amp is only capable of sending audio signals in the 30Hz to 15kHz range to these speakers. Unless, of course, you hope to upgrade your audio system such that it can properly drive these speakers someday.

In my desire to build an audio system that has the proper balance of individual component capabilities I’ve found myself struggling over the choice of a DAC. Basic technical specifications aren’t necessarily applicable here. The foundation of my system is a Woo Audio WA-33 headphone amp and Focal Utopia headphones. My music files consist of standard CD 16bit/44kHz resolution to Hi-Res DSD files. What I’m struggling with is choosing a DAC that would allow me to get the most out of this amp and headphone pairing. From the research I’ve done so far it is clear that the $23k Meridian Audio Ultra DAC would bring out the best of any system it is connected to. But does it make sense to purchase a DAC of this quality (and price) for my humble headphone system? Or would it be more appropriate to get the Chord DAVE (setting the MQA format compatibility issue aside for this discussion)? I’m currently using an Oppo 105D as my DAC and the music sounds pretty decent, but I know my system can sound better.

So I was hoping to get some input from fellow audio enthusiasts out there to make what may be the most important decision of my system build. I’m also looking at getting a PS Audio DirectStream Power Plant 12 to power this system. Anyone out there have any suggestions or thoughts on this issue?

YW SlvrSrfr, In my case I bought my apartment off the plan, and due to the layout of my apartment It would have been a messy and expensive job to install dedicated 20a lines into my audio room, or a balanced Iso transformer. And due to being a Strata development, I didn’t have the option of installing solar PV into mil-spec batteries, so the Gigawatt was a no brainer. If I was starting out & building a new home, I would probably go all out on solar PV, mil-spec batteries, dedicated 20a lines running into audiophile wpo’s, and overvoltage/surge protection. But the Gigawatt gives you most of those benefits in a single box.
There are many superb dacs out there and your headphones are excellent.

The easiest way to know is to borrow a great dac and then listen to the improvments it makes in your system if you can hear and appreciate the difference wether or not it is a speaker or headphone setup it doesn't make a difference then it is a valid upgrade.

We have heard the Merdian Dac nice piece you can do better for less money. 

You may want to consider a Lumin X1 the previous reference the S1 has been considered to be one of the best sounding streamer/dacs out there and the new X1 is reported to blow away the S1, at $13k it isn't cheap but for a world class Dac and streamer the price is reasonable the Lumin products are very musical and extremely well designed.

We are also not huge PS audio fans in terms of power products, in our tests the Passive conditioners were better.  Look at the Isotek Sigmas fantastic performace for the money. 

We have tested many brands of power conditioners from Audience, Shunyatta, Running Springs, Exact Power, Isotek, Audio Magic, Synergistic and a few others.

Best overall Isotek for the money, best performance Audio Magic.

Thanks Dave and Troy.  I genuinely appreciate your and melbguyone’s input.  I don’t have the option of trying different components on my system.  So the information I obtain from various reviews and forums like this one are all I have to go on before making what I consider to be once in a lifetime purchases.

If you're truly contemplating a $23,000 DAC, you need to find a dealer who will accommodate you.

+ 1. If you're investing that much money, it's worth even buying a plane ticket If you can't swing a home audition or find a local Dealer & go on a weekend break interstate.
