Separate DAC or continue using the Oppo UDP-205


Hello,

  I have all my music on a hard drive in FLAC.
I am a using Sonos Connect, Optically connected to the Oppo. From the Oppo (RCA'S out) to a Primaluna Dialogue     Preamp. The Amps are 2 Primaluna HP's. Martin Logan Theos speakers. I have rolled mostly all the tubes, and absolutely love the sound. Family and friends also love the sound.

 My question is, Should I continue going through the Oppo, or should I get a separate DAC? Nothing to crazy in price.
I have seen these things go for thousands, and thats fine if you can swing it. I was thinking around a $1000.
But, would it change the sound or would it pretty much be the same? In other words, is the Oppo that good at what it does?

 Since we are always tweaking our systems to make them sound better, I thought I would ask all of you first, before calling the salesman. I also have thought about  getting a turntable. But I gave away all my albums many years ago.
Buying a turntable, buying albums, taking care of all that stuff. Not really what I had in mind. I would like to keep it fun, and simple.

  Thanks

You can connect the hard drive directly to Oppo 205 USB3 ports (behind), then use Oppo Media Control app to select and play music files.  This method means you don't have to spend at all.

Oppo 205 DAC is very good.  If you want to play music files up to the maximum rates supported by Oppo 205 DAC (PCM 768k, DSD 512), consider buying/building a streamer without built-in DAC; then connect the streamer to Oppo 205 using a good USB cable.
I'm not sure how or why you're using the sonos instead of connecting the hard drive to the oppo and connecting the oppo to the primaluna.

I haven't heard the DAC in the 205, but have a 203 and 105D and used to have their headphone amp/dac. They have pretty good DACs. To me they are more "digital" sounding and less detailed than some others. 

A MHDT Orchid is a little more than your budget, but will sound less digital and will be detailed and neutral. To me, that would be a nice upgrade. It won't make a night and day difference, but will be easier to listen to and more "natural" sounding. 

I have a W4S DAC 2 and it is my least favorite of all the ones I've owned. 

Try getting the sonos out of the chain and see how you like the sound. If you still think you might want to upgrade, what do you hope to get from the upgrade? 
Thanks for the fast responses,

 I have tried connecting the hard drive straight to the Oppo, It would not work. Maybe because the hard rive is set up on a MAC ?

Thanks
Logan, 
The dac is solid, the output stage could use some improvement. I would suggest a Modwright "truth mod" if you wanted to take the player up a few levels in sound.

The DAC chip in the Oppo is very good.  However the DAC implementation in the Oppo cannot compare to many modern separate DACs.  There has been a whole industry built up just to make the Oppo DAC sound better.  But you can do far better for your money and have much more flexibility with a separate DAC.

As for which DAC, 20 people will recommend 20 different ones.
