Hi Joachim,

Thanks

Joachim,

Most of them are waiting for the GB components, as Fastron only delivered the inductors recently.
Hopefully some time in January, we'll hear the first feedback.


Merry Christmas,
Patrick

Hi All
Well I had a few hours to spar today so I decided to have a go at finishing off the Filter buffer.
Itís been up and running for about 1 hour and itís sounding very sweet indeed.
The first thing that I noticed at switch on was a much smoother more cultivated top end. I always felt that the 9023 was a little forward and slightly gritty at the top but the buffer seems to have done a nice job on that whilst keeping all of the air and detail.
Iíve been using a buffer with this DAC (DCB1 just as a buffer and MF tube buffer) for quite some time now but this one does a much better job of keeping the sound of the DAC intact.
It also has a little more drive and verve which is nice and seems much less cable sensitive (if there is such a thing) so maybe itís handling cable capacitance better than the solo 9023.
OK
Thanks Joachim to for sharing his work with me itís very generous and keeps the spirit of DIY alive and well.
Thanks to Patrick for making ideas a reality and for all of the organising skills that he used to get the filter buffer to my door.
Lastly thanks to WK for his matching and soldering skills without which this project would have been much more difficult. matching those Jfets must have been a real head ache.
I built version 3 and have it powered with + -9V Salas shunts.
It was only my second SMD build and TBH at first it was a little eye popping but itís doable with a little patience but I thank god that I did not have to solder those Jfets.
I like the sound very much
Great work.
Merry Xmas
