Dang it, I went ahead and ordered me an NFB-11 and an NFB-12, guess I'll get to see which of the DAC chips I like best before getting an NFB-10 :)   I got my Bijou ready and M3 nearly finished, copious loverly headphones to try so I can't wait to see it. There is only so much strapping tube...

Hi,   Have been looking at the XB700 for a giggle bass headphone.   Does anyone know if two wires from each driver goes to the plug? I.e is it as easy to convert to balanced drive as it looks with flat cable coming from both drivers.   //J

No it won't hurt, surely not, I am questioning if it is absolutely needed, at any rate I would go for a passive heat sink, nothing gets in the way of enjoying music like a fan.     //Jan

Ah yes, you are indeed right, I forgot about that part, On my board I have a jumper that can switch the I/V resistors between 270 and 120 ohm   Also changing the bias resistor (From pin 6 of the chip(s) to ground changes the characteristics quite a lot, I have a 1K trimmer in this position...

Ere, what do you get in the log viewer when connecting the device?   I never got to figure out what was bothering the Tealink device when I was on 10.5.8, by the time I went back to look at it, I had upgraded to Snow Leopard and am now also on 10.6.4, I now no longer have the problem.  ...

I have been tinkering with the TDA1543 for about a week now, running 8 of them off the I2S output from my Teralink, I find there is a distinct benefit from using 8 devices rather than 4, I would suggest that for the DIR9001 based board (Muse Audio) that ya'll are using a possible mod would be to...

Hi,   Has anyone had any luck getting hold of coolfungadget lately?   I have sent a PM about three weeks ago but have had no reply,   I wish to purchase a Mini-i and would prefer going to Coolfungadget direct rather than through eBay.   //J

The fail is overflowing like a love chalice full of, Eh WHAT?

I got my Teralink X2 today and have noticed a strange anomaly with it.   When I set it in the midi control panel to 24/96 it won't play as in iTunes (and cog) just does not play, the progress slider does not move, if I set it to 16/96 or 24/48 it does play. What gives? Anyone else experience...

I'm glad you like it..     I went a bit of a different route, I ordered the Teralink X2, a WM8740 on a DIP adaptor board, 8 TDA1543's and a 1541, I'll have a bash at setting the three of them up on breadboard and trying them with the I2S output from the Teralink. Yes I appreciate that the...

Quote: Yes I too assume it should read shouldn't I hope no one suffers any injury from contacting it to both, it can cause some pretty nasty effects.   I have never heard a Dac Magic, but it has been said that many similar and even lower priced units blow it clean away, maybe you...

Quote: Uh, I don't think so, if I understand it correctly oversampling takes place in a digital filter prior to DA conversion, some DAC chips have these filters built into the chip, some have features to disable the filter.   //Jan

This looks nice http://cgi.ebay.co.uk/DAC-DIR9001-TDA1541A-2-0B-parallel-output-OS-NOS-/320588294150?pt=LH_DefaultDomain_0&hash=item4aa48d2806#ht_2452wt_886 It is almost 4 times as expensive though and does not come with case or power supply.   Also it appears to be far from perfect...

Hmm yes, well the 1543 is listed as the 'economy' version of the family.   Something I'd like to do some day is cobble together a TDA1541A and a DIR9001 on a vero board, might be a kind of interesting project, the various factory made boards out there are all designed for CS8412/4 receiver...

Quote: Hehe, so do it! Once I get hold of one and rip it apart I will take some pictures and make suggestions for sure.   I don't think it would be a very good idea no, the lower limit for operating a TDA1543 is 3V with 5V being the recommended voltage and 8 being the max. But as I...

  Quote:   Yes, that is the single chip MUSE, it is a bit cheaper but the 4 chip one is obviously x3 more fun   Also that one you have there is the same as what is inside the delta sigma version of the Muse, it looks ok too but it is a different beast all together, it's...

Aha, I must be going blind, there is a second regulator in an SOT package right behind the switch. I reckon that drops the voltage from the LM317/LM7805 to 3.3V for feeding the DIR9001 and the 74CH00, if that is the case then it would be a very viable option to remove the larger regulator and...

The little chip by the optical jack is a 74ch00 I think, used to do things to the S/PDIF signal before it reaches the DIR9001.   The mystery of where the power to the receiver chip is coming from continues to baffle me, I am getting more and more convinced that the whole board is run on 3.3V...

Hmm, I'm still curious as to where the power for the DIR9001 comes from, if my eyes do not deceive me, that regulator is an LM317, which would be pretty trivial to set to say 8V to get more oomph from the TDA1543's, but it is nescesarry to establish how the DIR9001 is powered first or there is a...

I too am interested in trying a NOS R2R DAC without spending a lot.   I've been looking at this device for a little while now and something puzzles me.   Unless there is more components under the board, it seems to only have one regulator, yet I believe the DIR9001 requires 3.3V and the...

Quote: I believe it is yes, if I understand it correctly the mod was to install an alps blue velvet.   Yes you can do that no problem at all, that is also the way I would suggest going about it.   //J  

Quote: Hmm yes, my first thought was that it might be due to the somewhat high output voltage of the hiface that is rumored in many threads. But the problem is the same with optical output from my built in sound chip, so it's down to sample rate for sure.   //J

Quote:     I haven't no, but I doubt very much that would make a difference, I will give it a go in a few days though.   It's not really a big issue for me, if it gets on my nerves too much at the desktop I will just use the D1 as a front end for my SB3 which is 16/44.1 anyway...

Quote: Hmm, either my unit is b0rked or my amp is a LOT more sensitive than yours :)   //J   edit:   I will look into it some more at some other time, I am trying to reorganize my room at the moment and the D1 ended up in a box with some other equipment. Will try with a few...

Having now spent a few weeks with the D1 I am pleased to announce that I am still very impressed with the sound (bear in mind that mine is the Skyline modified version by ReiserFS)   The internal headphone amp works well with my Beyer DT770 (Pro 80 ohm) and the tube buffered output stage...
