Thanks Erik,

that is very impressive. I wish I could do quality work as you could. im only using 8volt ps for my whole setup.

Dimkasta,

I only have russian k40y9 0.01 uf on hand. I can send you a couple if you want. It might took a while for me to be able to compare it with the duelund. I compared the k40y9 0.01 with a k75 pio 0.1 and I preferred the k75. The k40y9 sounded a bit thin and bright. Soundstage was deep and wide with both. Bass is tighter with the k75. I ultimately preferred the k75 though I was comparing different values. It would have been fair if I was comparing the same values. The duelund beats both russian caps in all fields. I only have less than 20 hours on them so far and they already sound incredible.

Guys, let me know who wants the k40y9 0.01 uf caps. I have 7 on hand and willing for you to audition it.

Thanks guys

That's a pretty serious power supply Erik. Very nice work. Can you give the specs for the transformers for those of us who may consider building something similar. Thanks.

Hi guys,

since I've put in the 0.01 uf cap on the c906, it now has a hard time reading scratched cds. The 0.1uf cap did a better job in reading scratched cds. Anyway, im sticking with the 0.01 uf cap as it is just musical.

I have not compared 0.1 uf in different qualities...but then again a person cannot compare everything .

To me...it prooved over the last 5 years to be very stable with an 0.01 uF on c906.

True. This happens for me too.
I think of it kind of like when putting a better cartridge on a turntable.
You get better music, but it is also more sensitive to surface noise and imperfections.

Think of it this way if you treat your cd like a record (I always clean it with cd-enhancer and wipe it with sound cloth (anti static) and frequently demagnitize the particles in it before playing) skipping or not reading occurs seldom ( with 0.01uF on C906) and your listening quality is always top notch.

I learned that a cd is easily scratched so I have special bags (when they come in carton sleeves) and special cd boxes from Mobile Fidelity (lift mechanism).

Somebody out there who is still testing experimenting.......???

Howabout a Dexa Regulator and a 220 uF blackgate in front and a good 1 uf cap after instead of the classical drawing of the psu flying here around...???

I am curious what the results would be...either on chip or on motors...
