Which Streamer is a Major Upgrade over PS Audio Bridge II in a DSD DAC

This thread is ancient, and this doesn't answer your question really, but I have a DirectStream with Bridge II in my all Shindo system.  It never leaves me wanting (except that my 8 year old Bridge II broke the other day, and I need a replacement).  But it's a fine DAC.  

Just went thru a bit of a journey replacing my Bridge II. 
LOVE my DSD DAC BTW,  it’s going nowhere. 
First is budget. 
The cheapest solution I tried was an iFI ZEN Stream paired with a Matrix Audio X-SPDIF 2. This got me I2S into my DSD. AMAZING difference. All the noise from the Bridge II was gone. So quiet. And the Zen Stream is actually a very good Streamer. Definite improvement over Bridge. 
Now I am a big ROON fan, and I really wanted a streamer that could handle I2S directly, without a converter. 
I bought an A Capella III from Musica Pristina. All US made and Kevin is great to deal with. Also A Capella III is certified Roon Ready. 
BEST purchase I have made in years! I absolutely love this combination! The A Capella III direct I2S to the PSaudio Directstream DAC. Awesome!

Thank you all. As expected, many options. Neal

Lumin X-1.  End of story.

I am pretty happy with the Bridge II after converting my LAN to fiber last year.  I used to own a full Sonore opticalRendu (plus a uD and oM DX) setup with their best LPSs as well.  But that was when I had a copper LAN.  With fiber and utilizing a bunch (6 or 7?) of linear PSUs, my system has never sounded better.

Before getting a streamer I would consider auditioning an EtherRegen to feed the bridge 2. It really helped my system to sound better, and it will still be of value if you do get another streamer. PS is coming out with their own streamer with galvanic isolation at some point, which will feed the Dac via I2S. 

Maybe it would help if the OP, after apparently being quite satisfied with his current set up, is looking to change

Don't know if you are running Roon or not, but can vouch for the Bricasti M5 Network Player which makes for an excellent Roon endpoint.

All of them that play USB A.

Purposely got the DSD WITHOUT the card.

I own an Aurender N100 and W20SE. After an Aurlic Aries G2, and lots of PC, MAC and other streamer choices will not be straying from Aurender. It is what they do… and they do it incredibly well. Read a review of the W20SE. 

@nglazer Hi, I went with an Aurender N20 wonderful playback from onboard SSD or streaming. I don't know what your budget is but audition it if you can.
