When i reported my findings on the Leo Bodnar on Headfi I got the usual it will not work etc. I had 2 people message me behind the scenes who got the clock and thanked me. But no one else reported their experience. I gave up on the site after that Similar responses on FB ,a few people have taken the LB up and love it, but it gets tiresome trying explain...Many users don't know what a GPS satellite is....So you can imagine the amount of explaining it takes, l tend to recommend when my energy and my Chakra is alleigned, and when Mercury isn't in retrograde. |

I find the FB groups the worst of all. Full of agenda-monkeys who will argue the same tiresome points over and over again in each thread.
Not just the hi-fi groups, but car groups.
FB's lack of organisation also makes running a forum there painful.

Leo Bodnar tech guys have updated the Mac app for OSX so there is the sleep button function. Most impressed they have implemented this so quickly. Should get my LB clock this week!

I started with Mconnect on my iPhone then BubbleuPnP (on an Samsung android tablet) as the interface and functionality of Mconnect doesn't allow for easy browsing of your local music library files, it's basic. BubbleuPnP is better but not great.
These are connecting to a Sparky SMC with a laptop 2TB HDD (+Allo Shanti LPS) running dietpi and Minimserver. A wi-fi extender is used to isolate the router (dirty side) from the LPS powered switch on the clean side. The switch connects the Minmserver library server and the R26 via FMC modules, fibre is good to prevent electrical noise from the LAN switch and from the data stream itself.
Enter Jplay (from Jplay Femto fame on PC) was released late last year and is a very nice interface to use and has 'radio mode' functionality (plays random tracks from your library based on what you like) and a good history function which shows what you last played each month....... nice.
It's a bit pricey at £51 a year but I'd say is worth it for the functionality and does have a 'polling' setting which helps reduce activity on the network when being used, so in theory makes the app 'sound better'. Can't complain about that side of things, it sounds very good, if a controller app can have a say in things.
Certainly worth downloading if you have IOS products and try the trial version.

Been years since I used Jplay Seems like they have continued to improve the GUI

It only takes a couple of naysayers on a forum to cancel such discussions. We could fight back but it’s tiresome to go around these loops time and time again. That's the main reason I joined TAS. Had been in an ongoing argument on another website with a flat earther from Australia. Much prefer here. If disagreement, it's cordial; a discussion ensues. More a sharing of experiences rather than assault by opinion. |

I should mention the performance of the R26 with LAN input, it really is worth pursuing and is generally thought of a the best input for this DAC,
Here's a recent review on YT,
he goes into some depth about LAN performance vs I2S and USB.
I have found that keeping the LAN input as filtered/isolated from the router as possible pays huge dividends. The more attention paid to cleaning the signal of electrical noise on the LAN the more you don't hear! You are left with just the music, it's not a subtle thing. It's been said many times but that illusive veil is lifted. Things become more real.
I have been trying to evaluate HQplayer because there is so much hype around it, after a few weeks trying it in it's many guises upsampling to PCM 364,768MHZ, DSD128,256, it does make a difference to the sound there's no denying that.
But, it's a difference that seems to take away from the raw believability of the musician, being in the room when listening. I'm sure certain tracks benefit from the software upsampling but the type of music I like, no so much. It's as if the track is being messed with........you tend to listen to background micro detail more than the vocal, go back to red book and it has a realistic feel again, it is more enjoyable.
Really looking forward to trying the LB as this should have, hopefully I'm guessing as I have never tried an external clock, a profound effect on the focus of the sound.
Headfi thread on R26 is worth keeping an eye on there's plenty of good info, in case anyone is interested in FMC fibre modules I sorted my setup paying out just €31 (AliExpress) plus a decent dual output LPS adjustable 5-12v (ZeroZone €75).
You need a basic 100-300Mbps wi-fi extender first though to really make a difference along with the FMC's. The effect as I have said is not subtle but 'wow'

Exactly, I have been saying the same thing. Filtering / isolation to get the Ethernet feed clean is the name of the game. |

Rodders Are you using Roon or bubble and are you going direct to a intergraded, direct to a power amplifier or using a preamp

It's been one of those days today, nothing seems to slot into place, parts missing from orders, long phone calls and the god bothering squad on overdrive in our area today you know the sort of day which starts out really well and that heads towards the mason/dixie line at breakneck speed. The rest of the day regressed like a 50-year-old sloth on mogadon. So the big jobs were like naim at a musical reproduction contest, well out of place. What's on the small job rack I wondered, well blow me if it wasn't a Leo Bodnar clock in for some TLC. Repair a DC power jack and 'unfree' a usb cable stack as solid as a Star trek fan to Brent Spiner's coat tails at south end on Sea's annal geek fest. So one small ray of sunshine the nice chaps from Lecroy dropped in to say hello and left a couple of new 'additions' for the Mr. C test cupboard of wonder  Well feck it, I know I'll fix this great little device and see how see stacks up measurement wise, also I thought it might good to show you chaps cable issues in a real world dynamic measurement situation and just to throw a venerable hand-diaulic adjustable spanner in the moving parts a They are two plots for two genuine 50 Ohm cables both quality test & measurement standard 1m genuine 50Ohm BNC cables. All signals and amplitudes are identical just the cables were changed.
 Bear in mind both cables are matching 50Ohm impedences you can see the deviation on the fall time of the wave form here is pretty large around 780ps wheren are the rise time is far more stable around 11ps Using the Bodnar clock powered via usb power with cable A
you can see the deviation on the fall time of the wave form here is reduced by around 1/2 the value when using the lab power supply, the rise time is far more stable around 11ps so very little change is the variation of the rise time Using the Bodnar clock powered via lab power supply with cable A
Now using Cable B we can see a much more even handed deviation across both parameters at 1.6 & 1.2ns although a long time taken its more even plus the wave form far superior is uniformaty linearity departments Using the Bodnar clock powered via USB power with cable B  The next two images of Cable A and the lab power supply one a jitter analysis suit measurment
The next two images of Cable B with the lab power supply one a jitter analysis suit measurment  Now Cable A with the eye pattern (again lab power supply)  Finially Cable B with the same power supply & settings  So what's the take away here? Electrical noise (both power line ripple & conducted RF and electromagnetic inteference) can and DOES affect the signal integrity of the generated clock reference signal entering the measuring device along with cable propagationial situtaions/ and or shielding/construction and dielectric. So does this give us any indication that by addressing the situtaional measured awareness it has a direct correlation to any preceptual audiable differences we may precieve? |

Given all of the BS that sullying around the net with reguard to whether product A or B does effect things, I felt that clocks being a hot topic here along with cables and power supplies plus dac themselves I would be nice to demonstrate some quantifiable lab-based test that we can use as a basic benchmark.
Its a pretty straight ward indicator or whether outside electrical & RF or internal ripple noise can be seen is a controlled environment, with measurement traits that we use in the lab everyday to gain insight on any possible differences when designing electronic devices.
The bottom line is does any of the information confirm or disprove the statement That PSU is great,or you need to try this cable because its X/Y or Z, I can't say that only the person making that judgement call by listening can do this.
What we can say is this:
They are measurable differences in the factors that we would like at when deciding how to make those prototypes or cables etc and that there are correlations between the results and how those items deliver there SQ

I'd love to see this done for a sinewave clock, where noise intrusion is reckoned to be more destructive.

Hello All - Hope you are all well My first post on The Audio Standard - so please be gentle  I have a Gustard R26 and am using it solely with the LAN input - with Roon and LMS (UPnP plug-in). Overall, very, very happy with the R26 - but looking to see what else I can do to improve the sound quality of the R26 further. To this end, I am considering acquiring a clock for the R26 and I think there are a number of options and hence I would like to request some advice, please. Should I: - Purchase the LB Reference clock. This is a relatively low-cost option and is tempting but I am wondering whether I would be better off by buying something more expensive as a higher quality "once and for all" solution - E.g.
- The Gustard C18 clock
- One of the After Dark clocks
- The LHY-SW10. This would be my ideal solution as this network switch comes with a clock output. My hesitation is that LHY make no commitment as to the quality of the clock (no specs published) and it feels like it might be a lottery as to what I get
Options 2,3,4 would, on paper at least, appear to offer better technical performance than the LB, but I'm wondering whether the gains in technical performance from the more expensive options are going to be worth the extra cost in terms of improvements to the R26 sound quality?
Thoughts please? Opinions and advice greatly appreciated.
Many thanks in advance.

Personally if audio quality is priority, l would take a punt on the LB. l can't vouch for every clock, but l have had expensive an AfterDark set up and although they brought refinement and better details, the LB used with a,R26 gives you a level of detail and precision you may have never experienced,unless you used to high end gear costing £££. Being that you are already using a R26 DAC the LB should be a no brainer.
Also welcome to TAS! l hope you enjoy the forum,you'll find us a friendly bunch,with a vast amount of experienced members which also have a good sense of humour |

I think you're going to find it very DAC dependent. For instance, I prefer my AfterDark sinewave clock on the X26 Pro compared with a couple of squarewave clocks I've tried.
