I purchased a pair of the Evo 400 Power Amps and the Evo 400 Preamp last week. They are delivered and sitting downstairs but I have not heard them yet because I'm waiting for other equipment to arrive. The local distributor has the Evo's installed as well, and he told me via phone that there is a strong improvement in sound quality over the Dialogue series. I can't personally confirm this, as I have not heard them, and I never heard the Dialogue series either. But I can confirm that the amps look amazing and the build quality is the best I have ever seen in any amplifier. For me they replace an ARC VT100 original model which died a few weeks ago which I have owned since its release, and an ARC Reference 2 preamp which I still use. I also own Coincident Reference line and phono preamps which I rarely use although they are very good. When my other equipment arrives in about 10 days, I will report on the sound of the Evos if anyone is interested.
I am very pleased with my PL Dialogue Premium integrated. I feel absolutely no need to go "Evo" I can't tell what the extra $600 brings to the table.

You're gonna have a rockin system, assuming their hooked up to some equally competent speakers. 

It's obvious you're/were serious about playing records(Coincident) so, a report once everything is  online will be welcome.

Thank you tablejockey. I have some excellent speakers shown below which should make evaluating the P/L Evo amps easy enough. In the picture you will see a black and a silver P/L Evo 400. The distributor only had one of each but he will swap to all silver faceplates when more stock arrives. Same with Evo 400 preamp.

The equipment I’m waiting for is a Kuzma Stabi M turntable, Thales Statement arm, Lyra Etna SL cartridge and all Synergistic Research Galileo SX power cables, interconnects and speaker cables as well as PowerCell 12 UEF SE and Active grounding block. So there should be nothing holding the Evos back, hopefully.
My main interest is making vinyl transfers to digital, which explains the heavy emphasis on turntable and phono stages rather than power amps etc. I went with PrimaLuna because of the build quality and value for money. I’m very happy about the XLR inputs on the new Evo gear. I also have Nordost Odin XLR interconnects which I will be able to use now.

Here's a nice shot of the silver Evo 400 power amp, and one of the black Evo 400 preamp, showing the exterior finishes. I guess these are similar to the older PrimaLuna amps, though I have not seen them.
