Audio Grade Switch
Updated 2021 August 13

Handcrafted in Taiwan

Audio grade switch improve the on line streaming ( YouTube, Tidal …….),
Also NAS , dual PC mode playing.

2 switchs for double run  improve much more sound quality than single run.
Highly recommend to use double run.



Lay out of the single run








Layout of the double run,
Audio grade should be as close as possible to the Server or Streamer .

Lan cable make difference.

Recommend use the better Lan cable with # 1 , 2 & 3 ,

Most important Lan cable is the one from second switch connect to the Server.

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 !
