March 12, 200917 yr comment_214033 Yes I have, but it turns out that instead of getting the entire module, I was just sent the DAC chip . I'm not sure it's such a good idea to use the brand new one along with the older one. Anyways, I'm resigned to making a significant loss with the whole thing now. BTW, it turns out that the D20400A is voltage output: K&K Audio / Lundahl Transformers - UltraAnalog D20400A? - danlaudionut, December 04, 2003 at 00:29:31 ..so I guess the output is just a line-stage. I guess those Chinese tube DACs are doing something right . Well, SF probably did a better job at the design of it Anyway, whats wrong with using a brand new DAC with the older one? They probably don't have to be matched (each DAC probably drives a channel on its own). I'm sure your tech could take the old, faulty chip out of its module and solder in the new DAC. Report
March 12, 200917 yr Author comment_214042 I don't know what made you think they were sending an entire PCB (module?). It was pretty clear to me that they were just sending a single UltraAnalog D20400A module (more like an HDAM than a DAC chip). As far as trusting anything that is put up on AudioAsylum, do so at your own risk. Personally, I wouldn't. The technical level of many seems to stop at what kind of faceplate to use on their Oyaides... Well I asked them if they had any DAC modules and they said they would send me one. Here's the D20400A datasheet: http://www.vasiltech.nm.ru/files/D20400.pdf Report

I'm not sure it's such a good idea to use the brand new one along with the older one. Anyways, I'm resigned to making a significant loss with the whole thing now. My logic is preparing for its judgement now. Why not try to use the new and old chip? Its not like its a vacuum tube that could possibly cause channel mismatching, and I didn't hear of anything else not working for certain yet. Report

Well I'm going to do this anyways but I'm just disappointed that I wasn't getting something more.. Report

April 5, 200917 yr comment_221236 Hello XXII. Did you get your DAC fixed? If not, I am interested in buying your broken DAC if the price is fair. I would also pay for the new DAC-module you already bought, even if I don't need it. I finally need the power supply and the output stage, since I own a complete Digital board in nice condition for the SFD2. Regards from switzerland, Wolfgang Graf. Report

This is an example of a bad first post. Choose your second wisely. Report
