Very nice.

What PCBs are you using?

Still pondering wether I will make me an Aleph pre or buy me a secondhand X2.5 one day

acaudio · 26th December 2004, 05:52 PM

The PCB´s are my own design, made for the wima mkp4 10µF capacitors. Size 160x100mm single-sided.
Power supply are 100x75mm (2x 60V) with 80VA transformer.

thx
Adam

nice work .. Keep it up : O )

Nice boards. What do you have planned for the housing?

acaudio · 26th December 2004, 09:21 PM

19" housing with a sanded aluminium surface and steinless steel buttons will be nice, but this is a long way...

thx

Very nice, how does it sound ? Do you have other preamps you can compare this to side by side ?

acaudio · 26th December 2004, 10:37 PM

I listened so far with direct connection CD to my power amp (selfmade like Thel), see my homepage http://www.acaudio.de (under construction). I will compare this with another preamps when the relay volume control works. With headphones sounds smooth and sweetly but these have only 75 ohms impedance.

thx
Adam
