The Crescendo sounds alright if it not oscillates. The design is conventional in every respect, nothing weird. It's a well known design, diff input stage, high gain stage and MOSFET's. Maybe the lack of buffer between gain stage and output stage is a short coming.
Check my headphone amp QRV-01, very much alike it. The new Crescendo, called millenium edition is quite alright, real upgrade from the original.
