Leo Bodnar GPS Reference Clock Set Up

Something I forgot mto mention regarding the clock connections from the LB GPS clock they are 50Ohm, the Mutec & pretty most audio BNC inputs are 75Ohm

So as good as it sounds now imagine what if the reflections were reduced even more, so you can use an Impedence matching device.

For a far more matched impedence pathway I would recommend one of the quality proessional adapters

Personally I would leave it connected Bruce and just once a week recheck the GPS tracking via the laptop takes about 15 seconds

Having happily enjoyed the uplift in music for a few days and while waiting for all the elements to solve the impedance to arrive I started thinking . Now Tony set my LB Clock as he has indicated . Everything works and sounds fine but the output 2 light neve stops flashing as if although ticked as off it continues to look for a signal . Now when everything is stepped out to deal with the Impedance issue I am going to connect the LB Clock up to my pC and switch the output 2 on and set it to another setting than output 1 probably 24Hz and leave that . Nothing will be connected to it but it will lock and stop Blagojevich is annoying and I suspect using processing and electrical power now . I am not expecting it to make any difference but it will at least stop the flashing lights which will please me .

Questions if I may misterc ;

1. I have a dCS Delius DAC with wordclock input - can I use the Leo Badnar unit into it?

2. How does this compare to something like the PFM Flea clock if used to replace the stock crystal on a CD player

3. I also have a Philips CD104 & 204 heavily modified and using Abbas Audio external valve clocks, I’m almost interested enough to buy this unit just to compare the the valve driven clock (logically, I never understood why the Abbas clock sounds so good!)

Thanks, Richard

Thanks, but I could set the LB for 44.1? Most of my listening is either red book, or toslink. Thanks! Richard

Many thanks - I need to go read up on word clocks perhaps my Delius is also an early one, with no FireWire and only one word clock input…(same as bencat ) but I do not have the Purcell upsampler.

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.

Thank you for showing this Tony and as Chris has already said I am a little unsure about what it is I am looking at and how that translates to the final sound within a system context . I am assuming because it is closer to the perfect real Square wave and the digital eye is wider and neater that cable B would be the option to choose . But then again I am not certain that this is correct . I am also going with the thing I have found to be consistently true that using an LPSU instead of of USB (and in every case SMPS) has a direct effect in a beneficial way on the LB clock and probably every other item in the digital chain . As you have done with the LB clock would you be able to to advise a sensible BNC cable 50 Ohm that would be best to use with the LB ?

Okay I have none of the instruments that Tony does and I would not be able to work then any way . But I do have two bnc 50 ohm cables to use with my LB clock . Inspired by what Tony has shown in measured difference I decided that I would a swap of the cables and see if their is any difference . Now I freely admit that when I bought and had delivered a hand made cable from Pickerings I expected that this would be accurate and just be better than the cheap £15 job I bought from gear shop . Well just swapped them over and see no the cheap cable is far and away the better cable in my system . More clarity better soundstage and more life . I might ask Tony if he would test bothc able when I send my Mutec for upgrade and see if perhaps I prefer the worst measuring cable or if the cheap actualy measures better as well . So even here there are differences .

What do you use T?

Oh, a cheapie then 😂😂

I know T, I'm only pulling your leg.

Hi Bruce

That is an RG59/U with some quality crimped stainless terminations

Thanks for that Tony watched right through and pretty much understood what was shown and explained . The kicker is always though while the reflections will exist what will we hear ? By the way that is just a comment not a statement . To my mind anything done to get that signal as clean as possible is likely to help the equipment and circuit it is feeding to work more efficiently and so sound closer to the original .
