Low level listening
It has much more to do with noise floor than one would ever have thought. High eff speakers used with too much power are problematic as well since there is a fixed noise floor on any component and when a powerful amp is putting out small amounts o... 
A SHOCKING DISCOVERY ABOUT DIGITAL AUDIO
Bits is bits. CD is perfect audio. Wav is the same as lossless. FLAC is the same as the original. Such naivety. Now we have the hindsight to know how complex the data stream is and how so many untold things effect the conversion. It is amazing t... 
Tube DACs
It is not as simple as people think. Just because a dac outputs enough to drive an amp to full power or more we are forgetting that we almost NEVER listen at full output power. Instead we listen at levels close to 1w or so which in terms of DAC ou... 
Fantasy or reality? Inexpensive solid state preamps that get you 80% there?
I have a very different set of experiences and have found that if your budget is low then its actually easier to get stellar sonics from tubes than lower prices SS. The Audible Illusions or Musical Paradise 701 gets you much further than SS in th... 
My terrible Customer Journey with the Line Magnetic LM-503PA Mono Vacuum Tube Amps
@shkong78    That's interesting. Jack Elliano of Electraprint fame gave me a list of trade secrets before he retired this year and he has a similar note about not running a tube amp for more than x hours however his recommendation is 6hrs so it ... 
My terrible Customer Journey with the Line Magnetic LM-503PA Mono Vacuum Tube Amps
Well the plant in China that makes the LM (Foshun) sells their products through Taobao and other resources and I have their Western Electric 211 circuit Monos which have been extremely reliable. Granted I am a diy guy and I would say that the buil... 
Western Electric surveying market for (domestic?) mfg. of other tube types?
437a without a doubt!   
Electric cars will ruin late night listening?
Solar inverters is what we need to fear.  
Which Tweeter preferred- dome natural material, Beryllium/Metal or Planar Ribbon? Why?
If you buy the best example of each type they are all outstanding. So if we look at it in reverse , meaning what is the best cheap tweeter, it boils it down to something more fundamental relating to design. The best inexpensive tweeter is the ring... 
Next best exponential DAC quality level?
I really do not buy the thesis that an open soundstage with depth and delicate delineation is a result of some harmonic distortion from the use of tubes. I had a Goldmund 12 dac that has it in spades. I sold that to a local audiophile and hear tho... 
Next best exponential DAC quality level?
I believe you meant bandwidth determines settling time not frequency response, but it is not 100%. Phase angle, the load reactance and feedback also determine settling time. I was referring to the engineers who designed the regulators and Jung, ... 
Next best exponential DAC quality level?
Al lot of assumptions regarding image placement, soundstage and instrument separation being from extra harmonic distortion. I want to add that I am a retired prototype engineer with 14 years in consumer and medical electronics. I have made many m... 
Next best exponential DAC quality level?
I would not in any way call the Audio Note sound euphoric, syrupy or harmonically distorted. It on the contrary is very fast, open, clean and ever so slightly lean. There is a separation of instrumental textures and dynamic contrasts that make the... 
Next best exponential DAC quality level?
I recently had the opportunity to try out some of the budget DAC's in my system to see how they compared to my AN DAC5 Sp, which I consider to be an outstanding dac. The Dac 5 has had quite a few mods ( 768K Femtosecond input receiver ) as well as... 
High Fidelity Sound Speaker
Well I had a hard time believing it but the AER BD5 is one of the absolute best sounding things I have ever heard. Whizzer and everything. It really shattered my perceptin of what that genre of driver was capable of. The Sigma, which I have heard ...
