Does anyone have experience building one of these? If so, how does it sound and how much more or less did it cost you in parts? I'd really apreciate any input on this.

Hello. Anyone here build Zen headamp after 2003 ?

Original Article:
HeadWize - Project: The Zen Headphone Amplifier by Marcello Pellerano

I'm planing on building one. It will drive my Cresyns CS-HP700 (32Ohm) or Beyer DT880 (250) if it's owner will like this.

So here is my plans:
I'm planning to make handmade PCB (laserprint, have some exp). One symmetrical board for two channels. One trafo with two secondaries.

Power supply: all is as in article, but:
25VA 2*18V Talema (boxed, blue).
CRC filter: 6800uF caps from ca340a, R, 1800uF Pana FC.
Can I use R=4,7 or 10 ohms instead of 5.6 ?

I also have line choke filter, and X,Y caps for STEPS Power supply. And don't know, if it will be usefull here .
BTW choke is Murata PLA10AS3030R4R2B (30MH, 0.4A) If it has enough "current ability"?


Case : Hammond 1455-N2202 (220x103x53mm)

Main:
C2 = Wima MKP 2.2uf - If it's good choise for this position? I can get this for good price...

Thanks for Your attention
