TDA1541A non-o/s DAC PCB - Page 29

Hi,

you could email Pedja through his WWW site.

Also, the schema you showed above is a Nonos 1543 DAC - Pedja's DAC is a 1541A. Why not build both?

You can get a nice board (or kit) from Scott Nixon (DacKit) - I built one and it sounds very nice indeed through my TX102 volume control and mono amps.

The 1541A apparently sounds more "analogue" than the 1543 - I am looking forward to comparing the two!

Jon,
I've built both Pedja's 1541a DAC and Scott Nixon's simple 1543 DAC and there is NO comparison. Pedja's DAC is in an entirely different league and is as good as any DAC I've heard. You should definitely get going and build it - you won't be disappointed.

What is Scott's Webpage ?

Hi Gary,

that is encouraging - I'll start looking at gathering the parts over the next few weeks. I'm looking forward to putting this one together!

I agree with the first sentence, the 1541A is way more musical than the 1543 (great for rock but less natural), but I think that with the reclocker it beats hands down most of the commercial DACs available.

Hello All,

I am unable to locate a BAT49 with legs. For those of you that have assembled this DAC, where did you source yours?

Regarding alternatives, some say that using anything but the BAT49 will negatively affect sound quality... has anyone tried different diodes that can suggest a worthy replacement?

Thanks,
Bryan

Bryan,
Try looking in the parts wiki:
http://www.diyaudio.com/wiki/index.p...Parts+selction

and you will find the recommendation of the 11DQ10 diodes from IR as a good substitute.
