I am not an audiophile wizz but like listening to music (classical - vocal and instrumental and jazz). I recently bought Quads els 2905 speakers and tried them out with lyngdorf TDAI-2200 with and without roomperfect, quad elite system and 909 amp and Sugden A21. The sound of the Sugden I liked the most (extremely natural sound, lot's of air, beautiful image) but ran into problems when - even at sound levels which I do not consider extravagantly loud - playing certain CDs (one of the speakers consistently shut down). I was told that this amp was not strong enough for the Quads. I am now looking for a pre-amp/amp system that will match the sugden sound and is in the same price range. Btw the lyngdorf roomperfect system was not an improvement and both with and without corrections, the lyngdorf was inferior to the sugden. The quad pre-amp/amp is better but also inferior to the sugden sound. Can anyone help me out? I live in Belgium so need brands that are available in this part of the world.
