McCormack DNA 500 vs DNA 225 upgraded
Thank you for the response, @mitch2.  Very kind of you.  It is strange that the input imp. vary across the different model same series - 100k for DNA 225, 10k for DNA 500 and 13k for the mono DNA 750.  The measurements by Stereophile on the 225 s... 
McCormack DNA 500 vs DNA 225 upgraded
@stevemcx  What are the rated RMS and peak currents? I’m by no means an expert, but I wonder why your amp was designed with a low input impedance (10k ohms), which tends to create an impedance mismatch issue. Since it is transformer-coupled, could...

Maybe we need to learn Tai first.  To me, Atalante3 > Evoke20 > Totem Sig. One.

Congratulation.  Well done.   Falcon M50 can not be just $1,600, though.

Some reviewers seem to like it. @alvin1118 Will one be paying extra tariffs now? Do we need to be concerned for customs clearance ourselves? https://www.youtube.com/watch?v=DaGJ9s9nork&t=686s https://www.youtube.com/watch?v=H8yTCFLjOso

Used D&D 8c, around $8-9k. It comes with fully customizable DSP for specific room / listening space. Close to wall design.

@mattw73 It might not have the most punchy slam but the bass is accurate. It’s tight, detailed, & nuanced. It’s kind of weird, it doesn’t sound like it’s super deep or expressive but I can hear/feel it in the walls behind the couch..different...

@mattw73  According to Wave Theory, the new Denafrips 15th leans toward the bright side of neutral, in contrast to the warmer sound signature of the original Pontus or Pontus II. The treble resolution is enhanced, but it lacks the rich mids and po...

Wow, no apparent issue from 10k to 12k! Maybe I, along with many others, have been overly concerned. But here’s my experience: I used a preamp with a 5k output impedance into an amp with a 20k input impedance, and the sound felt restrained. Howeve... 
Do You Unplug Equipment During Thunderstorms?
yes

@mattw73 Thank you for sharing. If your preamp has an output impedance of 50k ohms, it should not have any matching issues with the Denafrips DAC, whether using RCA (625 ohms) or XLR (1250 ohms). I was referring to my own preamp, which has only a ...

@ozzy62 @mattw73 @klipscher @curiousjim @jastralfu @2psyop Does the high output impedance of 1,250 ohms from the Denafrips DAC ever bother you in terms of impedance matching? The Harmony DAC has an identical measurement, but the µDAC brings it do...

12v linear power supply
Only Teddy Pardo and SBooster list the most important specification: ripple noise/voltage. Teddy Pardo regulates it down to an impressive 1 µV. However, the SBooster ECO has a relatively high ripple of <1 mV at full load. It is recommended to p...
