Harmonic distortion inquiry
Does the THD of each individual component accumulate, or is the effect limited to the highest (noisiest) one component? Simple example question; if each device has .03% of THD for a phone pre-amp, pre-amp, and power amp, is the system distortion ... 
Atma-Sphere Class D… Amazing
Will the Atmas Class D be playing at Capital Audiofest?  Hoping so.  @mapman We're hoping to have it there in the Classic Audio Loudspeakers room. I won't be there.  
First Watt SIT3 vs Dynakit ST35
I've always had a soft spot for the ST35. I seriously considered finding one or building one up from scratch when I was looking into an amplifier for my bedroom system. But I realized it would be too large both power and size-wise so I built a sm... 
Microphonic from Vacuum Tubes?
So far I've only experienced this issue while streaming from Tidal or my own MinimServer running on my NAS.   @xcool Really! That is telling you something. In that case play the LPs only for a week. If you don't hear any pops, I'd look into is... 
Tube Amp for Devore O/96
@flipturn That speaker is easy to drive so you have a wide range of amps to choose from. Its not efficient enough (unless you have a small room) for SETs (which should not be run past about 20% of full power in order to avoid excess distortion) un... 
Microphonic from Vacuum Tubes?
I'm inclined to think that the culprit could be something with the preamp or the new tubes. @xcool  When you make a change and things go south its a good bet that the problem is associated with something you did. However, that bet can also bl... 
What is the “World’s Best Cartridge”?
you well know that the remaining members at WBF are all buddies of Steve or worse, Ron. They all follow the same guru and believe the same old BS that the guru pushes. Horns rule, and gear that is non-resolving and as bright as the sun is looked ... 
Microphonic from Vacuum Tubes?
@xcool Like I said, don't make any assumptions. Right now it sounds like you need to sort out for real which channel its in or if its in both. If its randomly in both, FWIW I'd be more suspicious of your source... but keep an open mind. That's th... 
Microphonic from Vacuum Tubes?
@xcool OK- keep in mind to make no assumptions. That can lead you on a wild goose chase. The first thing to do is swap the interconnect cables left for right at the amplifier inputs and see if the problem moves. If yes => the cable, preamp or... 
Microphonic from Vacuum Tubes?
Can someone tell me if this loud pop possibly caused by microphonic in my tubes?   @xcool  It isn't. Microphonics isn't a popping sound, its the tube being able to vibrate in such a way that it can generate a tone; in some cases I've seen it b... 
When someone tells you it's a $40,000 amp, does it sound better?
Veblen Effect Abnormal market behavior where consumers purchase the higher-priced goods whereas similar low-priced (but not identical) substitutes are available. It is caused either by the belief that higher price means higher quality, or by the ... 
Gain / Amplification
is there likely a quality-of-sound difference between utilizing maximum gain (say, out of a CD player, to keep it a simple scenario) and needing much less amplification from your amp, or is it in any way different to set your CD gain/output volum... 
Does Everyone Use 2 Phono Cables with SUT
@labpro As you can see cable capacitance is the name of the game when it comes to phono cartridges and SUTs. Its important to keep it down as much as possible. The transformer transforms everything- not just the output voltage of the cartridge. T... 
Electrostatic Speakers Vs. Horn/component Tweeter
My receiver won’t utilize the subwoofer if the main speakers are set to stereo mode and large speakers. Setting them to small, tells the receiver to use the sub for low frequencies and thus reduces the draw from the speakers. My receiver is biamp... 
What is the “World’s Best Cartridge”?
@mikelavigne Audiogon does not have an 'ignore' button, so you have to do that manually. In this case your enjoyment of this thread would likely be improved if certain individuals were put on 'ignore'. I hope I'm not one of those 😉
