Investigating if ultrasound is harming LPs
@lewm  " And you cannot even hope to detect such damage with a listening test, as someone else seems to claim. " If it can't be detected by a listening test, then just how bad can the damage be?  
Investigating if ultrasound is harming LPs
Methodology is a problem. Measurements need to be more precise. More sample points to do statistics. And then, have to decide what is gone - dirt or vinyl, and why? Too many variables to draw a conclusion. I've done a better experiment. I cooked... 
What to listen for?
Wow. No help here. I'm still stuck on the sound of magnesium valves.  
What to listen for?
Smoothness. Smooth, not dull; clear, but not etched. Smooth. Like real acoustic music. When I changed to film and foil caps, I heard smoothness. When I changed to nude Vishay resistors, I heard smoothness. When I changed to an air bearing TT, I h... 
Opinion: Modern country is the worst musical genre of all time
Yep, disposable music tends to be bad.  
Putting a new end on a XLR cable
I would NOT solder wires with teflon dielectric in an enclosed space, without excellent ventilation.   
Putting a new end on a XLR cable
BEWARE. Some cables use teflon insulation. When teflon is heated past 250C, it releases HF, one of the most corrosive and toxic substances known. You have a few alternatives: solder outside, at eye level or above. Or use a ventilated fume hood and... 
Do You Play Or Save Your Best Cartridges
Good thing I didn't hear that before it arrived. The one I have has absolutely superb fit and finish.

Heretic! Not that I've ever had one - what are they these days, 20k? And then there's the 25 years+ of aging ... About precision, it means you can adjust by ear to whatever sounds best. No-one, not even a Grado, can align a stylus to a cartridge...

@grislybutter You may surprise yourself. You don't need to do everything yourself - I sure don't. I buy off-the-shelf whenever I can. Prefer to just design and assemble, but sometimes a craftsman can't think of how to do it, or is too expensive....

Uh - because it's Romanee - Conti?  
Do You Play Or Save Your Best Cartridges
@grislybutter "I guess the rest of the setup would be just as expensive" Unless you DIY. I like to budget for something pretty good, like a 10-20k turntable or a 5k tonearm, and see what I can do with that money. That’s led me to an air bearing T... 
Do You Play Or Save Your Best Cartridges
@grislybutter  "what does a 10,000 dollar cartridge do better than a $1,000 one?" Absolutely nothing unless you have a comparable turntable and a comparable tonearm. If you do have these, you get smoother, clearer, more defined, more delicate, mo... 
New Synergistic Master Fuse
I suspect that all similarly rated fuses sound the same, but when you replace them, the contacts are remade and that's why they sound better. But - and it's a big but - a lower impedance fuse will sound better than a higher impedance fuse, and im...

Yes, but our own auditory equipment is deteriorating daily. I'm with @mulveling  on this - use your best until you discover something better.
