Okay extenders arrived and after LPSU shuffled around the shelves able to direct connect the LB . First comment is that after powering up again music played straight away . Briefest of listens is that it sounded fine and was not a huge drop from what it sounded with the bnc cable in place . However I know that inserting anything in the chain needs to burn in and settle down . So no more listening today just leaving the Cascade burn in track playing today and overnight and then have a listen tomorrow and make any comments then . I had to work out what you'd done lol Sounds interesting.

Music on this morning and very happy with how it is sounding now compared to using a cable . Lots of areas of improvement one of which is better levels of detail but without any hardness except when the recording has hardness on it. I like it when improvements are there but change is different for each recording . Every recording is different and so changes for each will be different reflecting the different quality of each source . I always have a niggling doubt when any improvement is a blanket one making all sources sound similar it may well be better but it could also be coloration . So this cheap and easy change is worth investigation to see how your system reacts. I have also before making this change (about five days) made a change to the LB settings advised by Tony after a brief exchange with LB . Tony advised using output 1 and disabling output 2 this works but the red led for output 2 stays flashing , this is because it carries the 1pps setting . LB day this will not have any effect on the clock but it is annoying . So instead disable output 1 and set output 2 as your signal provider and output 1 does not light and you still get the same signal .

Steve just another point I am finding that using just output 2 seems to lock on quicker and stay stable if for any reason I have to switch it off .

Thanks Andrew. The only thing I use my old work laptop for is adjusting the Leo Bodnar. If only I could remember where I put it.

Just a thought it anyone is following this and needs a male bnc to make bnc extender drop me a pm as I bought five in a pack and have only used one so could post out the spares .

Well a good few days with the direct connection along with Cascade burn in and I am not going back to a cable . This has now opened out and sounds better than any of the cables I have used or heard . Burn in seems to been achieved as it is sounding the same as yesterday so will just leave things . I have some 60/70,s Bossa Nova Albums and you can now tell really easily if they are sure guitar strings or plastic or a mixture . Loads of detail but no harshness and an even greater feeling of this being real people playing and singing . I have to say that I am really noticing recordings which are made with all the players in the same room you can feel the interplay and how they are bouncing off each other which just does not come across when they phone their part in .

Glad it's worked out!
Seems ingenious to me. Well done.

Afternoon Chaps, he is a very simple demonstration of why impedance mis matching isn't good for your digital sound quality!
This morning I was setting up a LB clock for a client and installed the new firmware and set up the parameters, I took a few images of a genuine 50 Ohm cable, a 75 Ohm cable and finially a 75 Ohm cable with an impedence equaliser.
Pretty self explanitory I feel

Pretty self explanitory I feel That IS obvious. However, in use one end will be a 50Ohm clock connector and the other end will be a 75Ohm DAC or DDC. So don;t most people have no choice but an impedance equaliser at one end or the other? And in the final pic, wouldn't you want the equaliser at the clock end since a 75 Ohm cable is pictured and you wnat the clock to see 50 Ohms?

Personally I would always use the adapter at the end as every time you have a impedance change reflections will occur. I have always obtained best results by using the IA at the end of the transmission line.
Some chaps just couple the clock direct to the dac etc via the impedence adapter!

I still don't understand why the 75 Ohm cable with an ending adapter is used in your last picture, as the clock see 75 Ohms, unless just to warn people off 75 Ohm cables on a clock. It would seem preferable to put a 50 Ohm cable with an ending adapter. I suppose a square wave example of that is somewhere on this forum.

The clock is 50Ohm output Bruce which is why the blue cable has the most desirable results sorry I should have pointed out.
