I recently sent my CSP3 in for the full Anniversary upgrade to include the bypass caps and tube regulation. When I got it back, I decided to take a look under the hood to check out the work. I was a little surprised at what I found.
It didn’t look the same as the photos I’d seen previously of the anniversary upgrades. There seemed to be fewer caps/bypass caps. The cap values looked different, as well. I wasn’t sure… Was this an error? A design change? Perhaps redesign due to supply chain issues or cost cutting with inflation? I didn’t consider it anything nefarious, but with current issues, there may be business needs to consider to keep things flowing. I just wanted to make sure it was done right and was upgraded to give the best possible sound it could provide, short of any tube choices I made. So, I emailed Steve. This is his response.
"Those photos I posted were with beeswax caps which have sense been discontinued. We now use Miflex copper foil caps which changed how we voiced the mod. Also recently a discovery revolving around the SG5B regulator tube internally installed showed better sound using it in series with the plate vs. with caps on it, so those were removed. This was discovered during the development of the 300B amp." I thought it may be useful to pass this information along, so others don’t have the same concerns. I will say, there is a definite improvement with the sound. I’ve had it a month and put in over 100 hours and I’m amazed by the resolution, dynamics and improvement in soundstage, especially depth. Definitely happy with the results of the upgrade! This is with my current solid state Schiit Aegir, that is in place until my SE84UFO25 gets built. I can only imagine how everything is going to sound once I have that in place!
