The diyAudio First Watt M2x

I have often wondered what is was about when a specific ceramic capacitor was specified to be used like COG/NPO or X7R. I knew if was about its dielectric but this short article gives a bit more information:

X7R, X5R, C0G…: A Concise Guide to Ceramic Capacitor Types - Technical Articles

It seems where a ceramic cap it needed we can always use a COG/NPO if it exists and there are space for it. Probably no need to go lower than "X7R" in "quality".

I am about to find the last missing parts for Cedarburg......
 
CE-DAR-BURG = A-MA-ZING!!!!

Implemented IPS8 in my amp....SUCESSSSSS! Hate to use cliche audio terms when describing sound but if I have to, then this is what I would say more air, impact, and realism than other IPS cards I tried in my amp. It is remarkable!

Mr. Mark Johnson, thank you sir! I am not good in articulating my preferences on what I heard from this daughter card, but I regret not building it sooner.

Wholeheartedly agreeing with this Cedarburg love-o-rama. I was/am a complete Norwood convert... But... Cedarburgs really aren’t getting swapped out any time soon. Thank you Mark!! (and Scott Wurcer!)
 
Asking a question out of my professed ignorance. I got a 24v meanwell SMPS to build a test bed for M2x daughter boards. Got my set up working fine, but when I test the V+ to V- at the daughter board level, I get 24v between the V+ and V-. I guess I need to get a 48v SMPS to get +24v and -24v at the appropriate daughter board connections?
