pl_svn Posted March 7, 2017 Share Posted March 7, 2017 pulled this morning my trusty, good, old 10/100 PaulPang switch from the chain was good 'till I only had a NAS and Mac mini plugged into it but since I started using Roon and an Aries as endpoint... it wasn't holding up anymore replaced, for the moment, with a plain vanilla Netgear GS105E gigabit but, even though I'm powering it from a good LPS (as everything else)... must confess I'm feeling "a bit nervous" LOL! so while leaving everything the way it is... I'm looking around Paul Pang now makes a gigabit switch and I've also seen this one by Jcat which looks the same as the AQVox re the Jcat vs AQVox it's not about price, just... so far my "don't buy from companies which go a long length about describing how their stuff does sound but say almost nothing about how it is made and why" has always proven right and both AQVox and Jcat's "technical description" look exactly the same Paul Pang too now says quite a little about his mods plus... the switch he is using looks an old and discontinued model oh, and... all of the above are 8 ports but 5 is more than enough for my needs (and available space) more ideas/suggestions?

pl_svn Posted March 7, 2017 Share Posted March 7, 2017 Funny! I thought I was crazy when I ordered a second D-Link DSG-105 switch to experiment with a battery powered daisy-chain...until I saw this on the link you shared to Paul Pang's website.[ATTACH]33752[/ATTACH] My wacky experiment suddenly turned into plain vanilla! I'm doing something similar here (but with just one PPA switch: the one connecting "audio devices") plus optical isolation between the two switches Qnap HS-264 NAS (powered by an HD-Plex 100w LPS) > Cirrus7 Nimbini v2.5 Media Edition i7-8559U/32/512 running Roon ROCK (powered by a Keces P8 LPS) > Lumin U2 > Metrum Acoustics Adagio NOS digital preamplifier > Metrum Acoustics Forte power amplifier (or First Watt SIT 3 power amplifier or Don Garber Fi "Y" 6922 tube preamplifier + Don Garber Fi "X" 2A3 SET power amplifier, both powered from an Alpha-Core BP-30 Isolated Symmetrical Power Transformer) > Klipsch Cornwall III headphones system: Cirrus 7 > Lumin U2 > Metrum Acoustics Adagio > Pathos Aurium amplifier (powered by an UpTone Audio JS-2 LPS) > Focal Clear headphones Link to comment
pl_svn Posted March 9, 2017 Share Posted March 9, 2017 ok, two days after pulling that PaulPang 10/100 switch and... I can't really say I'm missing something (even though I'm still nervous about using a "non audiophile" switch LOL!) It's a long time since I started powering the switch itself (plus all the stuff it is connecting) from some (good to truly great) LPSs back then, when I did, I "thought" there was indeed an improvement and a greater one than going, afterwards, from a "non audiophile" switch to the Paul Pang so... :-| think I'll keep (... for a while ) everything as it now is and try, instead, powering also the FMC and switch north of the "audio zone" ones from better PS. Don't think it is worth going LPS there too: maybe... just try iFi iPower?

pl_svn Posted March 9, 2017 Share Posted March 9, 2017 hhhhmmmm... I'm keeping all the grounding (and properly phasing) voodoo for when, some years from now, I'll hopefully move to the countryside and set up a "controlled" music room taking care, from the ground up, also of all the wiring/grounding stuff In this building where I have no idea what others might be doing with their grounds... =:-| (already using isolation transformers for pre and power amplifier. plus the LPSs for everything else) If was to spend $1000 on a grounding box... I'm sure a microRendu + LPS-1 for my secondary (headphones) system would bring a much greater SQ improvement And I'm already pretty happy with the main (speakers) one :-) Qnap HS-264 NAS (powered by an HD-Plex 100w LPS) > Cirrus7 Nimbini v2.5 Media Edition i7-8559U/32/512 running Roon ROCK (powered by a Keces P8 LPS) > Lumin U2 > Metrum Acoustics Adagio NOS digital preamplifier > Metrum Acoustics Forte power amplifier (or First Watt SIT 3 power amplifier or Don Garber Fi "Y" 6922 tube preamplifier + Don Garber Fi "X" 2A3 SET power amplifier, both powered from an Alpha-Core BP-30 Isolated Symmetrical Power Transformer) > Klipsch Cornwall III headphones system: Cirrus 7 > Lumin U2 > Metrum Acoustics Adagio > Pathos Aurium amplifier (powered by an UpTone Audio JS-2 LPS) > Focal Clear headphones Link to comment
pl_svn Posted April 23, 2017 Share Posted April 23, 2017 had the very same impressions as you when i switched (pun intended) from a plain Netgear gigabit switch to PaulPang's 10/100 one (now discontinued). only difference is... that one was "just" €150 shipped Qnap HS-264 NAS (powered by an HD-Plex 100w LPS) > Cirrus7 Nimbini v2.5 Media Edition i7-8559U/32/512 running Roon ROCK (powered by a Keces P8 LPS) > Lumin U2 > Metrum Acoustics Adagio NOS digital preamplifier > Metrum Acoustics Forte power amplifier (or First Watt SIT 3 power amplifier or Don Garber Fi "Y" 6922 tube preamplifier + Don Garber Fi "X" 2A3 SET power amplifier, both powered from an Alpha-Core BP-30 Isolated Symmetrical Power Transformer) > Klipsch Cornwall III headphones system: Cirrus 7 > Lumin U2 > Metrum Acoustics Adagio > Pathos Aurium amplifier (powered by an UpTone Audio JS-2 LPS) > Focal Clear headphones Link to comment

pl_svn Posted November 28, 2017 Share Posted November 28, 2017 no one is even sure it will be a switch. should however be "something ethernet related" Qnap HS-264 NAS (powered by an HD-Plex 100w LPS) > Cirrus7 Nimbini v2.5 Media Edition i7-8559U/32/512 running Roon ROCK (powered by a Keces P8 LPS) > Lumin U2 > Metrum Acoustics Adagio NOS digital preamplifier > Metrum Acoustics Forte power amplifier (or First Watt SIT 3 power amplifier or Don Garber Fi "Y" 6922 tube preamplifier + Don Garber Fi "X" 2A3 SET power amplifier, both powered from an Alpha-Core BP-30 Isolated Symmetrical Power Transformer) > Klipsch Cornwall III headphones system: Cirrus 7 > Lumin U2 > Metrum Acoustics Adagio > Pathos Aurium amplifier (powered by an UpTone Audio JS-2 LPS) > Focal Clear headphones Link to comment
