mrtakib said:The internal DAC on the Studer d 730 and d 731 gives a great sound on these machines. I was wondering if anyone had found or used an external more modern DAC that can further improve the sound?
mrtakib said:
On the other hand the D731 does sound pretty amazing just the way it is, so I wonder if it is even worth doing now.
I was thinking of connecting it to a DAC because I want to connect my computer to my hi fi system and if I do get a DAC for that, I want it t least to be an improvement for the D731 while I'm at it.
In the end did you keep your Studer "as is" ?

If you like the sound, don't change anything!

Thanks for that.But changing the NE5532's (IC402, IC403, IC452, IC453) won't hurt and is easy to do.
There are also 2 100µF coupling capacitors in the audio path, chage them to 47µF high quality types. (C411 and C461)

Remove and don't replace ??Remove the resistors R416 and R466.
Remove Q401, Q402, Q451 and Q452 (BC817, mute transistors)

mrtakib said:
What did you think of the DAC in them by the way ?
mrtakib said:
oh and I'm I correct in thinking that the jitter problem is only using the AES-output and not in normal balanced or unbalanced output ?
OneyedK said:
Partially correct, it depends on the age and the condition of the caps around the clock and in the power supply. The BB212 should be replaced, depending on how many hours the divice has been switched on.
If you can, borrow a DAC from somebody, if it sounds worse connected to the D731 than when connected to another decent player, you'll know your D731 needs to be taken care of.
2) remove C720, C721, R729 and X701. Connect a decent clock (kwak, tent, ...) to pin 2 of IC707
mrtakib said:btw, where is BB212, I don't seem to find that?
mrtakib said:
If I did go this route what happens to C720, C721, R729 and X701 after I connect a new clock, do they go back on ?
mrtakib said:
How is it you know this machine so well !
mrtakib said:I do like this player and hope to keep it up as best as possible. As for the future I think I will give a hard drive as a transport for non compressed music a go. There are also a bunch of ipod transports on the way that will bypass the internal dac and offer digital out.
OneyedK said:It's a great player, but if the transport dies, it's finished![]()
OneyedK said:[If that's finished, I'll start on a quiet Linuxbox to play uncompressed audiofiles.
I still like the CD as a media format best, not from a audiophile point of view, but I like to have a disc in my hands ;-)

Good luck with the modifications!
mrtakib said:I have seen Philips CDM3 's often on ebay, either from Hong Kong or in Germany.
mrtakib said:I was thinking of a Tent XO2/5 clock with an xo supply, the other I looked at was a Superclock 4 from Audiocom, but it's a lot more expensive.
mrtakib said:I should ask you this on another thread, but did you try your Opus dac after the Studer ?
I'm thinking to build something like that as a DAC1 or DA10 are a bit expensive . First I was thinking of it for the Studer, but now just for HD playback when I get around to that.
mrtakib said:Another piece I need to build from a kit or buy cheap, is a phono stage. Ever do that, any recomendations?
OneyedK said:What kind of turntable are you using? I've got one Thorens TD-160 and a Technics SL-1200mkII. Changed grounding connections on both. Ground loop problems are worse than a less than perfect phono stage.

mrtakib said:
I'll remember the ground loop advice. What did you change then to?
OneyedK said:A730: please describe the exact display problem, there are many reasons for the display to fail in these units.
