Listening to Guilty - Barabara streisand, Barry Gibb CD on the Pleiades 2n3053 single transistor per channel power amplifier in class A with no feedback

At your risk. Today Eleni from the excellent Record shop Record House handed me the anticipated CD. The amplifier is in more detail described on older posts. The output transformers are the hand made ones wound on small Siemens ferrite E inverted E cores with air gap added. Frequency respone which number of turns described on previous posts is flat 40hz to 40KHz with no negative feedback of cource. The sound quality is amazing. Breathtaking, promising. deep but not boomy bass, smooth mid and amazing extended treble whith no harshness, with sweetness and cymbals appearing to be real ones inside the room. Barbara and Barry in breath taking peformance. Signal path, cD - Sony CD Walkan line out - Pleiades 2N3053 2 channels - Celestion Ditton 150 at 2 m in a small bedroo with 3 differenct size panel low frequency absorbers. The big panel is behing the speakers away from the wall, its upper side only touching it and its lower side touching the wooden floor. panel in landscape orientation. Panels made of drawing frames with canvas with betumin roofing felt panel fed at the back side of them. Linoleum must be more suitable for enviromntal and cleaner air of room condition.
