My hifi buddy came over a few weeks to test out his Leo Bodnar GPS clock on my Di-20:
He gets dramatic results with his Gustard R26. Unfortunately, with the Di-20 we could hear no improvement.
This did prompt me to investigate one of the cheap 10MHz OCXO clocks from AliExpress. This arrived a few weeks later & I connected it directly with a SMA to BNC adapter. I chose this one:
I am powering with iFi Power 2 9v.
Immediately it had an effect. I could detect a subtle widening of the soundstage and maybe more detail. This was using Sine wave output. The Square wave gave a strange effect I did not like.
So I lived with the device for a couple of days and decided to box it, see if that would have further effect:
I also applied some dampening bitumen and a rubber pad on one end so it remains supported behind the Di-20 without straining the socket.
Then I re-did the testing, which I had not done for a few days.
Wow.....all I can say is I was shocked. The difference was so dramatic I wondered how I ever listened to the Di-20 on its own! I cannot be sure if this was due to the box, or the device running in, but for what it cost, I cannot believe it.
I have now ordered another cheap similar cheap clock from a different manufacturer to see if the sound can be further improved. I am now wondering how much hype is there in these expensive clocks............
