CS4397 dac

onboard output stage Implementation is now based on this http://www.diyaudio.com/forums/attac...amp=1204478039


I use minimelf resistors and smd PPS caps, AD826 seems to work well in this new stage where as it wasn't as good with the older implementation

Haha Marco. Sharing a love of the TDA1541A, SL1210 and DL103 - spooky!

Two words sum it up, mate:

"Discerning ears" ;)

Marco.

Me too I buy this after view web site CD DAC LAMPUCERA.

this man don't use and modify capacitor around opamp buffer output,

that's the best capacitor modification in ANALOG section and around OPAMP ?

First modification I change this OPAMP for LM4562 but AFTER ???

if you have complete list of your change in this DAC, because on LAMPUCERA web site it's complicated to know the brand and the type ??? WIMA MKP2 mixed with TANTALUM with OSCON oufffff ... ???

Is this a good idea to change all surface mount capacitor ! ?

thanks in advance ;)

I'm sure Leo will help you as he has a vast amount of experience in this field, however he's not on every day so you may have to wait a short while.

Just picked up one of these myself and stumbled in here looking for info. I'm a clueless noob so pointers on this dac would definitely welcomed by me as well. Looking forward to being here.

Cheers

Iain

Any questions Iain, i may be able to help as well.

I also use one of these and am just about to start doing a few mods to it.
Very good value for money, i reckon.
Where are you up to with it?

Sorry I'm late chaps, been busy and not had a lot of time

Currently still using the modified op-amp based output stage but got another one of these cheapo dacs so will try the Lampizator output stage on this one to compare

Theres only so much you can do with these dacs but it makes sense to get as much as you can out of them.
I'm still playing about with the decoupling, again the dac is limited because of the layout, I'll post more info as soon as I can
