Looking real good Terry can't wait!

Just have to decide what transport to modify  :o

A real pity I cannot test it... :( (16.93)

Anyway respect and love the persistence to pull it off  8)

Thats good news then as holding my breath was effecting my audio health  ;D
Differences in lay out too by the looks of it.

Finished and working perfectly. Will send a few to Kajak to compare.
I think these might be even better, nicer layout.

No more hand built clocks after this. Next batch will be on pcb's


ZZZZZZZ

Looking very good Terry, nothing beats top quality hand-built stuff! Mr. Kajak12 - QC Inspector, please update us when you get the comparison done.  8)

Serious piece of work.   Makes my Burson clock look cheap and nasty.

Excitement is building now.  Cant wait to put it in.     :D

It will be interesting to see (hear) what the differences are between the Burson and Zenclock.

It should be pretty damn good, I put a lot of work into these and the layout was
a little better which seemed to cut down the HF noise a little.

I switched quite easy with three clocks on the board and the result...Tent clock the least....Tricord second best and as very clear winner the Dexa... :o

Each had the designers own psu.

I have implemented the winner in my two Mini-Pitbulls (both belonging to audiobuddies) and will implement it in my PiTbull as well soon.

Pity yours does not come in 16.9 otherwise I would have been more than happy to install a fourth clock in my private mini shooutout  :D

Better pic showing the clocks with miniconnectors ...see yellow tubing on the right hand side... ;)

The Dexa Neutron star certainly looks very good. Looks like they went to a lot of trouble to optimise it. You do pay for it though.

Having said that, they still use an AT-cut crystal, non-ovenised oscillator. No matter how good the surrounding circuitry is
it can potentially never equal a good ovenised clock with a higher quality crystal.

It's a bummer you have 16 meg frequency, I'd love you to try the zen clock.

cheers

Eric,

Another thing that is -very- important.

You must place the clocks right next to the input where they feed and directly join the grounds or
make this connection as short as possible.

It is very probable that the Dexa actually won because it has a transformer at the OP which
makes a longer connection, especially with the HF shielded cable work -much- better and isolates
the grounds.

This was a very smart move on their behalf because all too often a huge part of the differences in
clocks that people hear is from their poor implementation WRT grounds, transmission length.

In the past I have done a test where 2 after market clocks were compared, one obviously better.
The loser had around 80mm longer length of cable connecting it to board. Once the cable was
shortened to 20mm and the clock moved closer, both were virtually identical.

I would advise for the tricord and tent, for the playing field to be equal, they must be mounted
-right- next to the destination board with very short connections, especially the ground. Further to this it's worth experimenting
with the clock OP resistor size. Too small (or none) will give the fastest rise time and potentially lowest jitter but
will induce ringing and bounce. As you make the resistor larger the wave will get cleaner but the sound will change.
There will be a happy medium somewhere. The type of resistor is important too - non magnetic.

Now, having said all of the above, I'm not discounting that the Dexa is the best, but merely that to get best results from
any clock requires careful attention to details.


cheers
