Snake oil, fraud, confirmation bias
As I see it, when divergent and highly polarized opinions are expressed about a subject, not only in audio but in most things in life, there is usually an element of truth in what is said on both sides. And the most correct bottom line is usuall... 
Anyone With A Class 'D' Amp Play A 4 or 2 Ohm Speaker?
I play them in extended mode. I have a very big room. I would advise caution in extrapolating from the results others report with different speakers!Even with the Scintilla. Not only does the impedance of your speakers go a bit lower than the impe... 
Anyone With A Class 'D' Amp Play A 4 or 2 Ohm Speaker?
Mitch, are you using the speakers with their "extended/normal" switch in the "extended" position (which iirc seemed to be the most commonly preferred setting), or in the "normal" position?In the "extended" mode the Kappa 9 goes down below 0.8 ohms... 
Can a Quality Full Range Speaker be the Limiting Component in a system?
Can a quality full range speaker be the limiting component in a system? Hi David,It seems to me that a "yes" answer to your question must follow from the fact that different "quality full range speakers," regardless of how those terms are defined,... 
The new Synergistic Research BLUE fuses ....
Tom (TheAudioTweak), thank you for your sincere, thoughtful, and well composed explanation. What you’ve written may be the best such attempt I have yet seen.   However, while I see no reason to dispute the possibility that it might explain the ... 
The new Synergistic Research BLUE fuses ....
Geoffkait 11-18-2017Sorry, no offense, Mitch, but you must have been snoozing since the way these aftermarket fuses work has been explained to death, including the various SR fuses. OK, you can go back to sleep, now. IMO the explanations that have... 
high frequency intermittent noise
almarg and or kosst_amojan, or others,Would the copper screening work well as a shield and reject RFI from entering through the glass window? Yes, Jim, I would think that a grounded copper screen would be effective against 700 - 800 MHz, since the... 
high frequency intermittent noise
... the frequency my stereo is picking up is in the 700 - 800MHz range. James, check out this link:https://www.fcc.gov/general/700-mhz-public-safety-spectrum-0The band extending from 698 to 806 MHz is used by public safety services, with part of... 
Do classical CDs made from early analog tapes sound better on your system than new CDs?
Inna, the OP may be too modest to say so, but I happen to be aware that he is an accomplished classical pianist and harpsichordist, whose background includes performances in a number of this country's best known and most respected venues.In the f... 
Do classical CDs made from early analog tapes sound better on your system than new CDs?
One of the most treasured CDs in my collection, both musically and sonically, is Chesky’s remastering of Jascha Horenstein conducting the Royal Philharmonic in a 1962 (!) performance of Dvorak’s New World Symphony. The original recording was engin... 
high frequency intermittent noise
Jea48 11-17-2017 ...how about when james1969 used the pro-audio monitors for the test. When he hooked them up he heard the same RFI noise. Just a guess the amps are SS. Yes, I had thought of that, and the fact that the same noise occurred with bot... 
For tube sound, which is more important: preamp or power amp?
Regarding the statement by Mr. Carver about the 50+ year longevity of the power tubes in his amplifier, I would point out that in general there are statistical approaches that are commonly used in deriving published MTBF (mean time between failure... 
Low heat alternative to FIRSTWATT J2 ?
Kosst, good points in your response to my post.  Thanks!Regards,-- Al  
high frequency intermittent noise
James, searching at eBay for "RCA shorting plugs" (without the quotes) will lead you to a number of sellers offering them at low cost.Good point by Ralph (Atmasphere) re the possibility that the amp doesn't provide grid stopper resistors in its de... 
Let's talk power cords
In the many threads that have addressed this subject over the years here, IMO the best and most informative single post that has been made is the following one by Atmasphere, which I'll quote in its entirety from the following thread:https://forum...
