Streamer


Streamer

15th/Aug./2016  Upgrade

Please refer to the user's feedback

Both 44.1 and 48 khz clocks works ok so far.

I'm using AES/EBU connection to another DAC (with AK4399 chip).
I notice rather big resolution and soundstage,
on some tracks I'd say it's huge.
Lot of air. Dynamic range is ok.
No harshness. Very impressive vocal, thundering bass.
Cann't say much about the depth of the soundstage,
because my TH900 headphones doesn't have the feature to render the depth(not like Sennheiser HD 800).

Will try to compare with the streamer's own DAC later.




Decided to stay with internal dac of the streamer.
The reason is that there's no harshness.
My old dac on AK4399 had big resolution but also some instruments sounded sharply.
In addition all musical instruments have 3d dimension on the streamer.
Very natural timbres.
Marvelously tasty piano.
Impressive, emotional vocal.
Cann't say much about the depth of the soundstage because it's not the strong point of my TH900 headphones.
The one thing I'd wish is to slightly lower the tonal balance.
Still, thank you Paul,
excellent piece for its money!
My dac was much more expensive.
Hope 3 seconds drops in the end of tracks and no option to play only one directory will be solved by the software developer.




$USD1499 plus $USD100 shipping

Could playing DSD music with an integrated amplifier.
It is the most easy & cheap way to play DSD music.

    For the Extremely Streaming User 
    Twin OCXO duals switch as 4 X run














    PPA FC10 Server



    Twin PPA OCXO Dual Switch




    User's  Feed Back
    Feed back 1: To summarize...left the switches and amps running on standby overnight .. Melody Gardot and Mark Knopfler was just amazing on Roon streaming off the internet. Had a very special air around the voice just like the LPs...better than my CD player! The PPA cables switches and streaming by far is the very best for the money spent. Feed back 2:
    Dual switch (single) slightly better than 2x OCXO lite....with same power cables and same LAN cables...
    of course it all comes down to the power regulators that i was using before

    so it is difficult to compare

    overall the results is more depth and instrument separation and slightly better dynamics

    new OCXO switch still only 30 minutes running
    so it will get much better in time
    already i like it though
    still not tested second dual switch
    now after 1 hr more body the new switch ...also i connected ground and even more body !


    bravo KaiYu !

    now 2nd dual connected !
    i hear more air around instruments....the instruments and voices have a more solid presence in space and better defined
    overall more 3D
    and slightly more body so far...2nd switch only 20 minutes on
    and better resolution !

    overall : i am very happy with my purchase !
    and lower noise floor as well KaiYu..
    the more i listen the more excited i become !
