Yea slower probably give people the wrong idea... relax as you said, the brain is taking things in easier and we are enjoying the music better .
Amazing you went and checked your turntable as I had a similar experience years ago after a few mods with my cd player.

I've had 'slower' on certain improvements
Took it to be separation and clarity, with space in between

due to the sheer amount of heat the X26 gives off Indeed, I laser gun zapped the X26 Pro today with the room at 20C and it's my hottest component at 26C. In the summer months, it runs well into the mid 30s. I give it lots of ventilation although the U18 and AfterDark clock sit on top of it. |

Martin, not sure what your laser gun would have read on those caps that were under the copper box...but they were very very hot to the touch. Went back to normal after removal of box...of course |

True Martin thankfully no damage done.
Clifford and l are already cooking up a way around this, we feeling a positive outcome. And we have also come to agreement that the X26 should really have some air vents to help remove the high temperatures.
Watch this space..

No Martin, that's why we are rethinking things.

It does have side air vents but it generates quite a bit of internal heat.

Well after a good listening session, I checked the dac, I had left lid off, I felt the heat from the dac, I lifted the copper box nearest the mesh off , the caps under that box had got very hot to the touch, not good, do removed it. The caps under the copper box nearest output section the caps were fine. I had read the x26pro does go warm.... It's drawing 60 w of quiescent current at all times and has no external heat sinks. A significant portion of that 60w of quiescent current flowing to multiple discrete circuits that are biased heavily into class-A territory. We must have posted at same time Damien...well I was typing as you posted My mind was is on other things, so slow to react. There is no reason holes can not be drilled in the foil covered cardboard boxes to vent them, like mesh will still act as a faraday cage, a few 3-4mm holes around the walls at the bottom, then a several holes may be 3 rows of 4 in the top over the hotter components should get an air flow. I did it with my external PSU in a steel box used for the heaters of the 2 x 6SN7 tube drivers for the KT120's in my power amp was hot now runs cool. |

Wasn't going to update till tomorrow,after another temp checkbut here's what I did today The box that was causing the heat concerns was modded abit. Under that box there are 4 pairs of caps that were getting hot,Damien and myself decided that I should cut 4 vent holes in the box, above the 4 pairs of caps and place copper mesh over the cut vent holes, this seems to have been a success but as I said ,I will check tomorrow to content myself. Oh before I modded that box,I took both boxes out first thing this morning and I did a rough test of the temp inside the dac itself, it got to 46c give or take a few degrees either way. With your suggestion to drill hole, I will drill a few around the sides, cheers for that. |

I just had a thought depending how the lid fits on the X26 would it be possible to put small nuts or washers under the lid lifting it 2 or 3mm possibly using longer lid screws, thus giving space to vent hot air around the periphery of the X26. not retaining the hot air generated might help it run cooler. |

Well Well Well lf the devil could cast his net... lt would be a copper sheilded one 🤣 So.. as you probably gathered...atoz and myself have been brain storming, and it looks like we have made a brake though... He seems to be happy 😊 And being that l have been at work today... l had the ideas and atoz was putting them in the practice. That meant l've had to pull my socks up 🤣 Tonight... l've added further sheilding.. Firstly to the regulators that enter the board from the power connectors. Secondly l have added an additional partition, which you can't see,but as a guide.. It's the the middle gap that hasn't done on atoz X26 between his audio and those ridiculously hot ESS chips. l guessing a bridge of mesh between will work for atoz on this. Lastly... I also sheilded the network board, l honestly don't know why l didn't do this sooner, after all l'm using it! So it makes sense.  More R26 Brings further improvements by Damien Read, on Flickr Well l've just been bending atoz on WhatsApp In a word WOW... Even from a cold start,and that includes the LB clock.. It was totally obvious that this had improved things beyond what l'd imagined possible.l am hearing deeper into EVERY recording deeply... Bigger soundstage.. Space, Dynamics Prat ... It's pretty scary..... Now something atoz commented on was Bass, now we both have low end peaks, atoz had reported that these peaks had reduced, they were still present but some how not as annoying. l mention this, as l've just had the same experience on a known track that gives me room issues, can't say l have a explanation for this, but perhaps we just cleaned the lower end up? Well..thats it for a bit... l hope this hopefully gives any TAS member a push or influence to give these mods a go. All l can say...there will be no going back. Damien |

If you where into manufacturing.. there's no reason why up couldn't make pre made sheildeds that could be placed straight on top of the PCB boards. However like a lot of manufacturers... they are more interested in the latest ESS or AKM chip that improves SINAD by a decibel, and use this as a selling point. |
