Back in 2015 – Magic and Microphony (Pt 1) – I suggested that the tendency to ‘microphony’ in some vacuum tubes / valves, can actually enhance the sense of ‘ambience’ or ‘live-ness’ of the reproduced sound.
The last thing I wish for, is a ‘dry’ or ‘threadbare’ sound that is lacking in ‘resonance’ or harmonic ‘decay’.

Sometimes it’s necessary to re-examine the little things, the forgotten details. Try to dig out the last 10% improvement.
Consider amplifier and loudspeaker connectors.
We know that music signals are alternating current, AC not DC – swinging positive/negative. We know also that “current in a conductor resides at the surface at high frequency” (Prof. Malcolm Hawksford, HFNRR Aug 1985): Continue reading →
When I first listened to DACs, I concluded quite quickly that ‘multi-bit’ DACs sounded more like music to me, than ‘bitstream’ DACs – more dynamic & ‘alive’.
The TDA1541 was originally developed by Philips (in 1985) as a high performance stereo DAC. The ‘A’ version was manufactured between 1989-1995. It was (is still?) regarded as one of the best sounding DACs ever made. This chip was used in almost 100 different CD players Continue reading →
Real music has dynamics. Macro-dynamics – with unrestricted headroom in crescendoes. Micro-dynamics – with subtle low-level information.
Music should be reproduced also with a ‘time’ dimension. Not just tempo, but each sound accompanied by an harmonic ‘envelope’, where overtones are produced and decay naturally – providing a sense of ambience, dimension and space. Continue reading →
