Hi Peter. Yes those are records and I did post that these were some of Gideon's demo tracks that he brings with him on set up.
As for Lamm you are correct, I did say that about Lamm and a prerequisite of mine when I ordered the speakers was that my Lamm electronics would drive them. I have posted here that 2 very large concerns of mine were put to rest with listening to these Plural Evo loaners
1.. I no longer have any concern about my Lamm amps driving these speakers. We had the gain on the preamp between the 4 and 5 position and there was plenty of headroom. Some tracks we had to turn the gain down lower. When I listened with my Wilson speakers the gain was usually between 5--6 (this is for digital), When we played vinyl and tape, the settings were virtually identical to those when I had my Wilson speakers)
2. I had concern that the size of the soundstage would be much smaller than that when I had my Wilson speakers as I had this preconceived notion that the sound stage would be commensurate with that of a smaller speaker. Such was not the case as the soundstage was equal to that of the larger Wilson speakers
