Please explain mono
  Sorry for my ignorance, but what is the purpose of mono in today’s day and age and with about anything available in stereo. I ask this because i feel that I’m missing something and may be able to learn something. Thanks   I own over 400 mo... 
Anyone listen to entire albums?
Probably 95% of the time I listen to both sides of an album. The other 5% I realize I’m really not in the mood for side 1, much less side 2.  I only have 1 “modern” reissue, out of 5,000+ vinyl albums. It’s Fleetwood Mac’s Greatest hits that I bou... 
My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s
@atmasphere  Output capacitance of a class D isn't a thing as you say, but output capacitance of the output devices is. Its nice to have that low for better switching.   Exactly what I already said. And “low output capacitance for better switc... 
My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s
@atmasphere To my knowledge only one company anywhere has made the claim that the devices they use are ’audio rated’ as you put it (although I am not sure they used those words, so paraphrasing). The only parameter that might make that so is th... 
My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s
  soix 8,602 posts 04-17-2024 at 01:34am  @wolfie62 Not really sure what you’re saying.  GaN FETs are clearly different from MOSFETs, and the performance advantages of the former have allowed amp designers to not only more seriously rival t... 
My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s
Its perfectly valid to compare amps of different classes of operation. Regarding the 'unobtanium' GaNFET, I understand your skepticism- I reacted the same way. The designer claims he uses a device 'designed for audio'. As you know, GaNFET's main... 
My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s
So much WRONG here! Comparing a Class D to an analog discrete amp, for one! Class D has far fewer parts and switching style supply. And that load of crap about “unobtainium” audio GaN MOSFETS!!!  Gees Louis!!! Switching MOSFETS have been used in... 
Eliminated my preamp with amazing results
Don’t you risk overloading your DAC this way??  
Speaker Spikes - Working Principle
So much BS in here ^^^^!!!!   Spikes under speakers serve to MASS COUPLE the speaker to the mass of the floor. It helps to change the resonant frequencies of the cabinets by adding the mass of the floor to the mass of the cabinets. Whether or not... 
GaN Class D amps are already outdated, it's time for GaN on Diamond!
The ONLY ADVANTAGE to a synthetic diamond base is heat transfer. But Class D already has that mastered. So where does this get you?? NOWHERE!! Class D audio amplification is NOT the purpose for a diamond substrate!! This is just so incredibly idio... 
Acoustically Treating a Bomb Shelter
Melamine Foam. It’s what you want.  
LP Thickness/Taper
I always check azimuth in the middle of a thrift store record. And several 1/1000ths of an inch matters not! Not in the real world!!  
Mains Power Cable DIY
Not exactly DIY, but….. Recently new power poles were put up on my street by contractors of the power company. The 3 7300 vac lines were raised to the top of a new pole. I asked if the same transformer was going back in place; they said yes. I as... 
As A Youngster, What Unit Puqued Your Interest In All This?
1965-1966. My mother worked as Quality Supervisor at Columbia Records’ Santa Maria CA plant. My dad built a mahogany cabinet to house his HH Scott tube and SS receivers, Lab 80 turntable, powering AR-2ax speakers. In 1966 he traded the ARs for Wha... 
My history with treble.
Took the OP WAY TOO LONG to realize what accurate treble reproduction sounds like!! By 1982 I was designing and building loudspeakers. I loved the Dynaudio 28 mm soft dome tweeter. I knew by then what clear, accurate treble reproduction was about....
