Reference TDA1541A DAC

Digital input section completed!

Updated 3rd December 2015 at 04:32 PM by dvb projekt

Now the digital input section is completed!

Wave I/O for USB input --> SPDIF/AES input board --> FIFO --> Isolator board -->
Dual Clock board with Crystek CCHD-957 clocks (powerd exclusive from a A123 Systems LiFePo4 cell) -->
Ian´s I2S to PCM V2.0 Module --> Red Baron

Because i use two Red Baron´s parallel, i added two additional U-FL connectors for DR and DL.

Tube-I-zator Output Cap Upgrade

Posted 3rd May 2013 at 03:23 PM by dvb projekt
Updated 30th November 2016 at 08:58 AM by dvb projekt (Sound review added)

My last dream come true!

The output cap upgrade to the holy grail...

DUELUND´s CAST PIO Copper Cap!

Therefore the Tube-I-zator must go to the 2nd floor

Sound review

Now after ~150 hrs. burn in time, i will share my impressions with these outstanding caps.

I had a déjà vu after changing from my previous Mundorf Suprem silver/gold/oil caps to the Duelund CAST PIO Copper.
The same difference as in my 300B mono block´s.

This openness, clarity, three-dimensionality with so many more subtleties and micro informations, absolute breathtaking.
Only the Duelund CAST has

Personal announcement

Posted 26th March 2013 at 05:24 PM by dvb projekt
Updated 26th March 2013 at 05:27 PM by dvb projekt

Well my friends it is time again to say thanks to all of you, who like and ordered my pcb´s.

Because i am no developer of electronic circuits but have the knowledge to design pcb´s,
i wanted to give something back to the community.

Since i started with my 1st pcb, the Optical-Volume-Control on 15th October 2009,
a small donation from every sold pcb goes to diyaudio.com

Today i am proud to say that your cumulated donation achieve

$ 3104

Keep on having fun with my pcb´s and best regards

Oliver

The best sounding I/V resistor

Posted 3rd March 2013 at 10:22 AM by dvb projekt
Updated 30th November 2016 at 09:17 AM by dvb projekt

As many of you know, i am using the Texas Components TX2575 Bulk Z-Foil resistor for a long time
in important circuit positions, especially as I/V resistor.

Recently i stumbled over a short recommendation from Thorsten Loesch.

In my commercial designs we use a specfic type of SMD resistors after auditioning tons.
Some SMD resistors are really bad, some are so-so and some are most excellent, though no patch for a Rohpoint Squaristor GR102.

Ciao T

Because i know Thorsten as a man who had the perfect sound in mind,
i ordered one pair 30R to try them in my Tube-I-zator.

NOS TDA1541A double crown

Updated 30th November 2016 at 09:23 AM by dvb projekt

I am a lucky man!

I´ve got two NOS TDA1541A double crown DAC´s from a friend

He bought the last from Philips a long time ago...

Just now i swapped them on my Red Baron modules...

What could i say.... They will never leaving the DAC modules again !!!
