I was introduced to PL last year when a buddy brought over a Dialogue One for me to listen to. He runs the top of the line VAC pre/power amps but started with the Dialogue One. He has >500k into his primary system. He listened to my system and didn't think I was getting the most out of my Magico A3s. Magico Speakers have a reputation of not being the easiest speakers to drive. He was correct! The Dialogue One sounded AMAZING with the A3s but didn't have quite enough power. My wife came up to the listening room and said "How can you go back to the Yamaha after hearing the PL?" She's not into the stereo that much so for her to initiate the decision to upgrade amps was a great and welcoming sign.
I went with the EVO400 power amp after auditioning ARC, Ayon and Dynaco amps. The EVO400 drives the A3s incredibly well! Amazing body, sound stage and overall sonics. My buddy came over after I got the PL and said he was impressed with how well the EVO400 drove the A3's as well with the overall sonics. His speakers are Magico S7s.
You get great bones and choices with PL. Ultra Linear or Triode modes, Auto Bias, etc. Being able to run any power tubes in the amp gives you tremendous choices to tailor the sonics to your liking.
This year I'm planning on adding the EVO400 preamp with a separate phono preamp, The Herron VTSP-3A is the front runner on my short list.
Keep in mind that there is so much that goes into having good sonics. I've heard people say that the room accounts for 50%. Prima Luna is a good bet to be highly satisfied with your amplifier choice considering all of the factors that go into generating awesome sonics.
