…and this with I2S input! What sound may we expect in simultaneous mode with Ianīs pcm board….

Letīs see…

Hi Oliver,
I'm not very familiar with Ian's pcm board or operating in simultaneous mode, is that something that can be easily integrated into your design,
or does it require a total overhaul of the unit with all of Ian's boards?
Please keep us informed with plenty of photo's and sketches as your unit evolves.
You know what they say, "A picture is worth a thousand words".

Hi Ned,

you could connect Ianīs PCM board easily in front of the Red Baron V5.0. It has a normal I2S input. The two jumpers on the RB must go to simultaneous mode. Thatīs all.

Ian will do some test with the RB V5.0 shortly and post his results here.

Cheers,
Oliver

So, Ian's fifo board is a good fit with the red baron?

Lot's of options on IAN's board - it's got me puzzled.

Default Red Baron and S2

I am a happy camper. After searching for close to a year, a fellow Canadian provided me with an S2 double crown. Now very motivated to rebuild my TAD1541A DAC with proper case, Oliver's Red Baron and great power supplies. Currently enjoying standard tda with burson regs, lampizator output and Grundig DEM all driven by WaveIO.

The sound currently so good I was having trouble getting motivated to rebuild without birds nest wiring and many prototype reworks. Now with Oliver's very nice board and the S2 and S1 beckoning it is time get going. As always this will take a while. Look forward to digging deeper into this audio classic.

My plan is to build the ALIX processor and WaveIO into the DAC box to ensure shortest possible USB, I2S and power lines. Probably some 3D layout. Also inspired by Lampizator layout with inverted tubes and one box layout with isolation of areas. Thanks Oliver for providing a very nicely laid out PCB to host the TDA.

I'll let the source of this part speak up or stay silent. He has quite an inventory of TDA1541A chips.

Hey, I picked up a couple of tda1541 chips too.
Which tubes are in your lampizator output stage?

I've got an amanero, and like the waveio I think it might be a bit overkill for the 16 bit tda1541 chip. I'm not sure what I'm going to do with the usb to i2s input yet.

I'm also looking into that fifo buffer for red baron.

The WaveIO works superbly with the TDA1541A, esp with a good PSU. Highly recommended.

I am using a pair of NOS Tesla E83CC Gold Pin (1:1 to Telefunken ECC803S).
