My first PSA piece was a Delta 100 power amp, which for me bested an Adcom and B&K, although a McCormack power amp did put the PSA Delta 100 on the sidelines.
Along the line, I got a couple of PSA power cords, a wall socket, and a used PowerPlay IPC-9000 power conditioner, and with good results.
Fast-forward a bit, and after realizing I needed to incorporate a DAC into my system, I went with the PSA Stellar Gain Cell Pre/DAC. They had a combo deal initially with the S300, so I got both at the same time, and took advantage of their generous trade-in program.
I immediately loved the sound. I don't know if it was just the change to Class-D that I was liking, but I liked it. After a while, I incorporated balanced/XLR connections between the pre and power amps, which raised things up another level. The quality and fullness of sound at lower volumes is what really impressed me. I was getting the full frequency spectrum without having to crank it up like I did with A and A/B. And the noise floor is REALLY low...dead quiet...so much so that I first thought something was wrong, until the music played. I was used to the low-level hiss from tweeters with A/(B) when you put your ear within a few inches.
Several months ago, I got a deal I couldn't pass up on a new Cary integrated SI-300.2d. I love all the features it has, and the sound is excellent, but eventually I went back to the (literal) efficiency of the PSA combo.
Next, I replaced the PowerPlay 9000 pc with a new Stellar Power Plant 3 regenerator, and today I should be receiving the Stellar Phono Preamp. The phono pre will be up against a Rogue Audio Triton that I absolutely love, so we'll see.
As everyone else has mentioned, customer service is outstanding. Even during this COVID-19 crisis, they have been very responsive and helpful with my recent purchase. Jake, there at PSA, has been my go-to guy.
Btw, they will be launching their line of loudspeakers very soon, and they also sell AudioQuest interconnects now.
