@gryphongryph It was the amp I had when I bought the speakers. I'd say it is on the neutral side, however my cables are warm, my DAC is an R2R NOS, and cables are on the warm side, and so I find everything works well together.
When I went to listen to the speakers at the dealer, it was connected to a D'agastino Progression amp that sounded absolutely amazing. However it was more than I was looking to spend.
I actually had never heard of Graham prior to being in that shop. I had wanted to hear the Harbeth 40.3 XD but no shop that I called had any to listen to. After hearing the LS5/5, I bought them without even listening to anything else. They make music sound so natural.
