Could you post some pictures of upgraded PS and eleborate on this?

  There is not clearly mentioned that USB, HDMI, TOSLINK cable cannot run 100 meters. But for example ethernet cable can :) I2S may work longer than 0.5m or may not. Depends on many factors For example here are recommended Kitsune i2s-hdmi cables...

  SU-1 has some kind of isolation. Read these: https://kitsunehifi.com/product/singxersu1black/ http://www.head-fi.org/products/singxer-su-1-usb-bridge/reviews/16649   Because SU-1 always need +5v on USB, you can power USB separately via split USB cable (or device that do the same like...

  It doesn't matter if you have F-1 as a full, finished-product or just a board. The only possibility to power it separately is to use USB LPS and split USB cable like this  http://forzaaudioworks.com/en/product.php?id_product=46

  0.5 m for I2S interface is very long. I2S was developed for very short internal distances between a transport and DAC many years ago. For example in CD player. So there's no I2S standard

  You can't use mck/wck because NAD M51 has no input for it. I'm using Squeezebox Touch -> USB -> Singxer SU-1 -> digital XLR -> NAD M51 -> XLR -> Plinius SA 103 (power amp)

  Ok, it's clear now because I read it can connect to network infrastructure with switch etc.

  So it isn't possible to use one port for VDS and internet simultaneously? 

  Speaking of Rednet and DSD/DoP...Is Rednet capable of DSD/DoP or it's the SPDIF output that limits it?

  Is your DAC capable of 32 bit PCM or you downsample to 24 bit in foobar?

  Why extra ethernet port? Can't you use the one you already have in your computer?

  Hi   Please compare Rednet 3 vs Mutec if it's not a problem. How huge is the difference...ethernet vs very nice USB DDC   Rob please do the same

Thanks, Yes, I know. Galvanic isolation, DDC with different interfaces, recklocking, DSD/DoP to PCM conversion, word clock, etc. Real Swiss army knife in a one box. Not all of us can have all these nice boxes in the room. And F1 has some sort of galvanic isolation too.   Summing up (in...

  Rob, could you answer?

  For me the "naked" one looks like different version without Ethernet socket

  Thank you Rob for the effort. I know it's not easy to downgrade the audio chain :)   But to be clear. In these setups the Mutec (alone) was better than F1 powered from Teradak DC30W? And using PPA in both cases makes small change?

  You can easy change foobar's look with skin like DarkOne (i'm using it right now) http://tedgo.deviantart.com/art/DarkOne-v4-360862076 But it doesn't matter in the end because it's uncomfortable to control foobar with keyboard and monitor when you sit at the front of your speakers. For...

Sorry, corrected:   Quote:

  Expensive, of course , but designed for pro audio, with all multiple channels and solutions/capabilities one does not need in stereo. But AFAIK there is no two channel audiophile solution yet

  It all depends what is your favorite player :) Mine is SB Touch and squeezelite which I can use everywhere in my house from one server(PC/NAS etc) :) Hardware players (SBT) isn't of course free

  There is also Rednet D16 AES with direct AES/EBU connections (IN/OUT) and SPDIF. https://us.focusrite.com/ethernet-audio-interfaces/rednet-d16-aes

  Yes, you're right. My bad I didn't read to "remove metal cover from one end" But the source device must be properly grounded.

  I don't know roon or sooloos but Squeezebox software (server, players, most plugins) has always been free (GPL) and is maintained by big community till now.

  Removing metal covers is not good solution because shielding inside cable (without grounding) can act as antenna.  With STP all devices have to be properly grounded. In consumer market network, with consumer market LAN devices it is hard to achieve. So better one uses UTP

  Have you had a chance to compare in these setups?
