My SACD Transport feeds so much better signal to my DAC compared with streaming end...

I use an Aurrender N100H with an Ayre QB-9 20 DAC for my headphone system. My virtual systems are posted under my UserID.

I use an Arrender W20SE and Audio Research REF CD9se for my main system. I have also tried other streamers and DACS like dCS, Grimm, Berkeley. 

I recommend Aurrender, even if used. Outstanding sound. I have tried others in lower tiers and have not found them as good. The DAC is no less important and I have found tends to have a greater impact on tonal balance, the streamer on detail.  fullness and noise. 

There are lots of good DACs available. I assume you are in the market for a less expensive ones than I have. Just be careful to make sure it is musical. Comparing sonic characteristics using AI is a great way to help you zero in on one. You’ll are unlikely to  be captivated by the sound if the components are over detailed and analytical sounding... it is the midrange warmth that conveys to emotional content. 

@ghdprentice Thank you. I just decided to go for a used MSB Discrete with Renderer V2. I will likely move my Ideon combo to a future headphone chain if my life will need that. Even in that case, I will still do some streamer upgrades over the Bluesound Node. My experience with the PST transport makes me realize that the entry-level Ideon DAC sounds amazing and certainly punches above its price, and that it my current streamer is a bottle neck. Aurrender sounds like a great option and I will certainly be looking for it on used market if I decide to go for that path.

I have a BS Node N130 and I bought a Teddy Pardo LPS for it and it made a very nice improvement in the sound. 
 

My two cents.

@curiousjim That's two great cents!

I have to concur with Ghdprenice.  I purchased an older N100 to try streaming with an Aurender.  I can honestly say the sound exceeded my expectations.  I no longer am interested in physical media.  The streamer is all that I want to listen to for the ease of operation and sound quality.   I have posted my PS Audio SACD transport for sale and plan on purchasing a N200 or N20.
