l actually wonder if LB are aware that Audiophiles are using there clock?

Shame they don't do a audio version, with a on and off sleep button, rather than having to plug it when powered down.

l still think if TAS was giving awards out, it would get my vote of product of the year

l think when John tested it, he was still getting to grips with the LB, before we all made the discoveries of different settings.

What l can say, using my R26 with a Audio GD and AfterDark was good, ditch the Audio GD and AfterDark clocks,and add a LB totally different league in terms of detail, speed texture,actually the Audio GD sounds slow in comparison.

But it would be good to retry with optimum settings,sadly it resulted in me moving the GD on.

When I tested it was only a few weeks in and I didn't know how to get the best out off the clock.

I am not aware of any firmware or software updates during us having the unit,so l would say it experience from Tony and other members that have discovered better settings

I have an old Sky TV cable next to my system running to a Sky dish on the roof. Wonder if this would work instead of the antenna included?

An interesting aside re external clocks…it is for me anyway. I originally assumed an external clock would replace the functionality of the internal clock. Probably everyone else was more clued in! It seems than an external clock can work as a reference for the internal one. This explains my confusion when my R26 running with my LB displayed EXT ERR and the DAC still played music, I now understand how and why this happens.

How a DAC or reclocker handles an external clock therefore is an important factor and may explain why sometimes the results aren’t as expected or do all external clock inputs work in conjunction with the internal one?

The DAC should not display EXT ERR (looks like a Gustard) if the external clock is indeed a 10MHz clock. The only time things are different is if you have a DDC and are feeding the external clock via said DDC using the I2S interface. In that case, the DDC should be set to REF EXT while the DAC is set to INT but will use the incoming clock via I2S.

I’d better clarify - Usually my Gustard R26 does not display EXT ERR this only occurs if I unplug the LB or move the LB which one of my stiff LMR-400 cables connected - there’s one cable where the BNCs are a little slack and have to be very well aligned to ensure a good connection.

I comforted by the logic of the external clock (LB in my case) working in conjunction with the internal clock. When I’d assumed the internal clock would be disabled when running an external clock I struggled with the logic that a clock plus cable with two connectors would be often better than an internal clock. Often great play is made of how good internal clocks are. Now I understand that an external can be additional reference for the internal clock, finally I’ve grasped a little of what’s going on 😀.

It's not necessarily the case that other DACs use an external clock in this way.

Indeed, it seems dCS make great play of using a PLL to supplement the internal clock. Some of their documents talk about jitter from external clocks being unavoidable and therefore simply replacing an internal clock for an external one would decrease quality. I wonder which other DACs that include an external clock option operate in a similar way to dCS and Gustard DACs.

On the subject of cables between the LB and R26, it sounds that is a critical component.

Short of wiring directly onto the R26 internals why not just use a simple in line RF BNC connector so the LB is hardwired onto the rear of the R26? That's what I intend to do with my R26 and LB when it arrives..........

I always like to keep things as simple as possible.
