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 !

    1. Hi, Sarah
      Thanks for your comment.
      I have to write for all customers to be aware of the version of the switch if you are a audiophile listener. You may request an excellent sound quality that a high performance switch should do. So please choose a gigabit (GS) model together with v3 (OXOC module) or above.
