The D90 is well-rated a bit more sparkle up top according to a review I saw on YouTube I'm expecting good things but Ive just seen Hans Beekhuyzens review of the Holospring May. I have been very keen on their R2R approach. I may not make a move for anything unless I am 100% its what I want. I dont plan on pissing about with DACs like I did phonostages lol |

I was just glad to get an hour's listen in tonight. Even from stone cold in a cold room, it's sounding quite marvellous. The LKS is still improving.

The system is in a very good place now, making everything sound wonderful. I don't want to touch it, just want to keep on playing  |

This is good to hear. I must come over and listen to hear the changes sometime soon.

Sure, John. Let's take it to PM and set a date.

No FOMO or jealousy here; no sir!
Seriously though, I’m glad it’s all worked out... I’m interested in this especially because I’ll ask Tony to fettle... everything when I’m back.
So what’s next?!

The core system is done, but there are always small fettling options, Martin. Tony put an idea in my head about grounding the ethernet sockets in my router - at the moment I'm just grounding at the 0V DC power plug (which in itself makes a considerable difference). Looking at ethernet, there are four twisted pairs and I'm unsure of which pin or pins represents 'ground plane' and what other grounding vendors like Entreq and CAD do for ethernet.
There is also the option at a later date of adding an external clock to the Mutec MC-3, either their own Ref 10 or Tony's external clock design.
To be honest, I've done so much that I'm very happy to have a long period of stability now. The last time I hit this peak of musical satisfaction was with the modified SEG driven from a Pi 3. I wanted more resolution, dynamics, slam, bass, focus - more insight into the music. I've got those things now, it's on another level completely. Time to just enjoy.

I don't think Cat5 is grounded is it, but the shielding on Cat6 and Cat7 is so you could use a Cat6 plug and connect the metal shielding to the grounding box I assume.
Interesting idea and as the AQVox SE switch has a grounding terminal on it, and I have a spare spade connector, I might try linking that to one of the CAD units. It's about time I rationalised my grounding solution from the random connection approach I have at the moment!

Yes, I think I'll leave the router alone as I'm already grounding the 0V connection and I don't want to cause it stress by bringing a floating ethernet line to ground.
You should definitely attach a grounding box to the switch, it may surprise you!

I will certainly try, but the switches are connected to the Fidata server and the NDX2 using AQVox's Edge Cat7 cables and they are grounded to the CAD GC1s. Whether that continuity is sufficient I guess I'll find out.

So stick a grounding device in almost any hole in your equipment is what Tony is saying? LOL
He has run out of standard holes (xlr,rca,usb) so is suggesting ethernet now?
Surprised no one has thought of using them on TV's
Oh sorry someone has!

Grounding a router definitely makes sense. However, not necessarily via ethernet. I ground the DC 0V on mine, as well as feed it from a linear power supply. It really benefits streaming.
By the way, the BR Eflos USB into my streamer is very effective indeed. Makes a huge amount of difference and obviates the need for the ifi Purifiers, in fact it's better off without them.

Have been having a scan through this thread. What a fantastic room and set up. I feel I ought to tidy my man-hovel up and take a few pics. My room is more at the Poundland end of the scale..... |

LOL! I will say it does make a great deal of difference if you don't share the room with other functions and have no TV in it. I like keeping it tidy and its easier now.
Decorating it and choosing the colours was my treat.

I have just got back from visiting Martin
We had some pretty deep chats, exploring music and personal meaning towards what we heard. I really enjoyed the conversation. It is rare I get to explore this with someone else.
Some great music choices from Martin
Martin did an experiment with his grounding box onto the Mutec, adding his grounding boxes, made a nice difference. They added more depth, making everything sound more natural
Well done I feel all the work you down is really taking your system to the next level.

Thanks, John. I really enjoyed the conversation and your company.
Just to explain to others, the number of permutations of grounding arrangements can become extreme and it's not easy landing on the best arrangement. I thought I was close but not quite there. With John here, I tried rearranging with all four of my SGS-1s cables going to the Mutec, the BR Eflos Phono going to the LKS (digital) and leaving the BR Eflos USB going to the Asus.
We both agreed it was a step up, with John perceiving that it eased the musical flow and opened up the soundstage and me perceiving that a touch of hardness on voice had gone.
That's a good result for a simple 30s tweak.

I have to say that grounding the Mutec reclocker with my SGS-1s grounding box using all four cables has worked unexpectedly well. As before, it takes a long time for the SGS to settle down but my word the performance has really stepped up in microdynamics. Every little transient sounds almost explosive and electric guitar can be very striking and effective, much closer to the real thing.
The Mutec clearly has a lot going on with its ground plane and needs the noise taking away.
Playing a track like Chris Isaak's Baby Did a Bad Bad Thing is incredible with his voice and the crunchy guitar soaring in dynamic intensity.
