Hello
So I hear you cry, is there much difference? well yes there is but it needed the Duelands to bring the greatest improvements without which the new clock brings more width, air and height / depth but not all the calm space in between notes and eveness. This should not be underestimated as the dark, fraction of a second between notes makes for a more enjoyable performance and easier time listening to the macro details in the music, is it worth investing in, I think so. Mario mentioned a rough price which is much less tha a lot of the pimp shirt salesman price tags Get your DIY orders in early, I feel sure you'll enjoy the uplift for not a million dollars. Shame one of my top CD players uses a non standard frequency or I could be one of the firsts to enjoy it in the longer term.
Thanks vtv your feedback is appreciated. I'm not surprised the 2 x duelunds made an improvement.
Note that the 2 electros used were cheap Rubycons out of my cap box also all resistors are plain Jaycar MF and carbon film types.
The proto clock was made with parts I had on hand - see where the basic design sat performance wise, there is scope for improvement in some areas.
I generally resist using parts like Duelunds and try to wring every ounce of performance other ways before resorting to them - they
just don't represent good value for money in the scheme of things. But if users want to upgrade that is fine.
For the next batch the following improvements are planned:
- Better quality resistors
- Better quality caps (where electro are now)
- oscillator itself will be same generic type but higher spec model with a)slightly low phase noise b) 5 to 10 x lower
sensitivity to vibrationally induced jitter.
- Proper custom designed pcb with optimised layout for noise etc.
My aim is to get the performance past the level of the clock now (with duelunds) but without needing them.
cheers
