Power Sensitive Components

My new system has sounded wonderful until this recent heat wave. Then I noticed at times a certain loss of clarity and some slight glare. Mostly likely due to power issues. I started to consider a regenerator or conditioner. But first I thought I would try upgrading the stock power cords. As I described in another thread I purchased a Cable from Ice Age Audio. Their Frankencable. After a 50 hour burn in I tried it in my Accuphase amp. Didn’t do much. Accuphase strongly recommends that you use the supplied cable. Then I tried the DAC. My MSB Discrete has two power supplies. One for the digital conversion and one for the analog output. With the cable on the digital supply the sound improved noticeably. I then moved it to the analog supply.  A slight improvement. Probably because the digital supply was now back to the stock cable. Then I moved it to the Aurender N20 streamer. Again a noticeable improvement especially to the soundstage which was wide with  impressive depth and instrument separation. . Really impressive. So I left it there. The next day I noticed that while the wonderful soundstage was still there that loss of clarity was still there also. It was hot and ACs were running hard. So the power issue was back. So I decided to move the cable back to the digital power supply. That cleaned up the sound a lot removing the clarity issues. However the soundstage was not as impressive as it was with the cable on the streamer. Luckily I have two more of these cables arriving on Friday so all of the source components power supplies will be addressed. What I found and suspected was that the DAC supply is the most critical and probably power hungry of the three. It runs the warmest of them. Even warmer than the amp. Now after getting the cables in place I still sense power issues I’ll probably get a PS Audio Powerplant 3. This summer is going to be really hot. Trying to avoid that expense but after spending a lot on my components I’m not going to starve them of the power they need to perform the best.
