cleeds—I'm not personally aware of any other evidence of controlled double-blind testing that indicates a statistically valid audible distinction between redbook and higher rez alternatives. That's why I was interested to see your reference, altho...

cleeds—Re. "Hi-Rez Audio Distinguished in Blind Testing": Any findings derived from an experiment involving 7 testers (average age 22) in a anechoic test chamber listening to test signals (not music) just doesn't convey much of material significan...

cleeds—Thanks for the reference. That's relatively new data; I hadn't seen it before. No time to review now, but will get to it soon.Previous blind studies (all relatively old) had always indicated no statistically valid distinction between redboo...

mbiondo—Re. sound quality, current redbook CD is as good as it gets; refer https://classicalcandor.blogspot.com/2020/01/on-cd-quality.htmlHigher resolution programming sources are not going to provide any audible advantage, although the power of e... 
Parasound A21+ or PS Audio S700 monos?
Attn. Tweak1—Re. Parasound A23, if your A23 is running HOT it’s either deficient (a defective part, or circuit improperly repaired or altered), or it is extremely confined and without normal free air circulation. A fully "in spec" A23 won’t ever g... 
Considering simplifying my system... talk me down (or whatever)
pinkyboy—You've got the right idea, but your scope is off. When I reached age 82, in 2012, we concluded that it was time for us to simplify and downscale. So we moved 12 miles from our suburban bayside house into a modest but adequate condo that's... 
Advice on Krell amplifier
fast—Yes, the Krell info that you pointed me to is very pertinent; thanks.  And the DC servo correction that they cite should prove of material benefit in minimizing DC offset drift. As a consequence, I still don't comprehend why Krell doesn't pub... 
Advice on Krell amplifier
Numerous responders here are Krell amp. owners, so lets ask them to chime in…Hey Krell guys, what DC offset do you read on your power amps? Simply read the DC voltage present at your amplifier's output terminals under a NO SIGNAL condition. (Use a... 
Advice on Krell amplifier
There are three basic limitations implicit with all high-end class A power amps, so be certain that you're prepared to cope with the challenge that they present: (1) They're big, heavy beasts that generate a lot of heat, so the installation has to... 
Used vs New vs Vintage vs Floorstanding vs Bookshelf vs ..... OMG!
Re. jhw9’s comment about the stability of modern polyester film crossover capacitors… Yes, poly-film caps are surely better than the old oil-filled crossover network caps of yesteryear—also those awful “non-polarized” electrolytic caps that proved... 
Used vs New vs Vintage vs Floorstanding vs Bookshelf vs ..... OMG!
Here's some well-intended advice for "tykozen", and anybody else who's considering the purchase of used loudspeakers: DON'T. You will regret such purchase, and if you don't, it will only be due to your disregard for diligence. (E.g.: You failed to... 
Will a subwoofer add depth and clarity to my system, or just bass?
To OPTIMALLY separate the (low bass) subwoofer passband from the (mid-bass) main woofer passband, it's necessary to use a full 4th order (24dB/octave) active Linkwitz-Riley crossover. A simple (generally passive) 2nd order (12dB/octave) crossover ... 
Will a subwoofer add depth and clarity to my system, or just bass?
Tim—With respect to the use of subwoofers to reduce room-related resonances, hey, the more, the better! Of course, most listeners have constraints that prevent adding more than two subwoofers to a modest-sized listening room. Certainly two is my l... 
Will a subwoofer add depth and clarity to my system, or just bass?
A couple of clarifications…One of the major benefits to be derived from the addition of self-powered subs (use at least two, generally spaced wide, and towed-in from the front wall corners) is that they'll help you defeat room mode peaks/nulls. Th... 
How can I punish this Chinese audio dealer
Vacuum tube commerce has collapsed in the 40+ year lapse since I abandoned them. All of the principal domestic, British, Dutch, and German producers are now either defunct (like Tung-Sol Electric, my employer from ’57-’60), or they’ve long since c...
