Removing stylus from Shure V15 Type III
@wturkey  Hopefully someone didn’t glue the stylus to the cartridge to eliminate “resonances.” Could only have been my Dad!  Too late to ask him. More likely there has been some corrosion - the pin connectors have suffered.  
Removing stylus from Shure V15 Type III
Thanks, I think I have been overly intimidated by the word "gently". Worst case is I might damage the old stylus - the cartridge body looks robust enough ...  
Looking for a simple system
Go KEF active speakers!  So many advantages ...  
Directional wires/cables
@dlevi67 Thank you for the very thorough demolition jobs!  
USB and Coaxial at the same time?
@erik_squires USB of course is the only choice for very high resolution formats and DSD You are really ruling out HDMI?  Really?

Devaliet's amplifiers are a modern take on Quad's 405 and later "current dumping" amplifiers.  A small Class A amplifier is used to top up the difference between the actual and ideal output from a beefy "high current" amplifier.  The Quad 405-2 so... 
At the top of the line is it really all that different?
@deep_333 Or better yet, expand into object based multichannel audio/atmos, etc. Yes, especially when you consider multi-channel SACDs have been around for 25 years!  The Atmos recordings from www.2L,no are stunningly good.  As is DSOTM in Atmos

@atmasphere  You can't hear the 'transition' and the amp isn't any more linear in the 'class A' region than it is a few Watts above that. Thank goodness ChatGPT did not "know" those astonishing "facts"!  
Class A bias, speaker sensitivity, watts...?
@invalid True.  Even the electron has its spin!  
Class A bias, speaker sensitivity, watts...?
@tomcy6  What was it you mentioned?  
Class A bias, speaker sensitivity, watts...?
@tomcy6 I've been trying to think of the physics that may be responsible.  When an AB amplifier is in Class A. the bias voltage is sufficient to accommodate the signal swings.  If the impedance of the speaker drops, more current is needed to keep... 
soft dome versus hard dome tweeters
For what it is worth, the KEF Reference series uses aluminium drivers and aluminium coils. According to KEF's white paper, the ideal tweeter dome shape for best dispersion is spherical, but the best shape to resist distortion in pistonic motion i... 
Class A bias, speaker sensitivity, watts...?
@tomcy6 Not my understanding at all! The relationship that requires double the power when impedance is halved applies to all amplifiers of all classes. Solid state amplifiers exhibit an anomaly at the crossover point from +ve to -ve output volt... 
Class A bias, speaker sensitivity, watts...?
@tomcy6 I’ll tell you what I think I know and someone can correct me. Class A watts approximately halve from 8 ohms into 4 ohms, so you have between 5 and 10 watts of class A power. You invited a correction, so here goes.  (If you were talking...
