Bricasti DAC owners

Thanks for the heads up!!

As per Bricasti's SIM Chip instructions (Bricasti V1.11 MDx Upgrade for my Bricasti M21 DAC firmware updates ), I removed the cover of my M21 DAC and inserted the SIM CHIP in the marked slot.  The SIM chip was very easy to align and insert. I had no issues and it works perfectly.  I also changed the setting to wide.  

After reading their instructions, I was concerned about finding the slot and inserting the SIM chip.  However, when I removed the cover, finding the slot was easy and I had no issues.  The location of where the chip needs to be inserted is clearly marked and obvious.  YES, you have to be CAREFUL inserting the SIM Chip and I used a flashlight to help me.  Once you power up the DAC, please watch the screen for a progress report and the words PROG OK.  Any questions, please ask. cheers,  

I recently changed the setting on my Bricasti M21 DAC (simple setting on the front panel) from a ladder R2R DAC to a delta sigma DAC. This is a test and I have no final comments. However, the ladder DAC seems more relaxed and musical while the delta sigma seems more direct. To be honest, I like both options and the ability to switch back and forth.

Bricasti Customer Support says “Sigma delta came along and basically replaced R2R more than 20 years ago. It was the next generation of technology and promised better performance: lower noise, distortion, etc. The reason you are noticing the R2R appearing smoother is the resister ladder is less efficient and slower than sigma delta which basically up samples to DSD rates to do its Job. You can hear it clearly when you listen to something very transient like a snare drum hit. With the ladder the snare almost disappears compared to the sigma. Personally, I prefer the Sigma Delta, but many people love the R2R. That’s the beauty of having them both”.

My Bricasti M21 DAC has the MDx board installed and the Bricasti V1.11 MDx Upgrade for (also for the M1SE, M3). My Bricasti M21 DAC substantially improved the sound quality of my audio system. To my ears, everything sounds truly outstanding. The music is clearer, less dark, better bass and sounds more like music.

From my first hearing a Bricasti DAC, probably in 2015, I immediately thought this was great, not merely great for digital. I bought an M1, and in the years since I added the MDX board and 1.11 firmware. Still thoroughly satisfied. I run my DAC with the Minimum 1 filter and on “wide”. When I first bought my M1 I used it with my CD player as an external DAC. By 2016 I was listening to high res downloads via a MacBook Pro. Since 2021 my M1 has been used nearly exclusively with a streaming transport.  So while my use had changed my satisfaction has not. 

@zavarto, Thanks for the great suggestion. I will change the Master clock sync to 'wide' and see how it sounds.
