Vincent is playing through very recently acquired pair of ProAc DT8's before that Monitor Audio Gold's. The amp has a tube preamp section, a total of 3 tubes, and a solid-state output. The amp is slightly on the warm side as you said you like. Tube preamp section. It has a solid and tight low end, images very well and is transparent enough to let you hear the subtleties of whatever music you're playing. For me, it was a good choice and feel I got a lot of amp for the cost. Solid engineering with an excellent build. Doesn't get the big reviews in the large magazines like others but a very good integrated that will hold it's own against anything out there today.
