A lot of hype about PS Audio, deservedly so ?
I was running and enjoying my Perfect Wave Tansport into a Wyred 4 Sound DAC 2 SE for several years using the I2S interface. Recently, I found myself downsizing/selling much gear so I tried the Stellar Gain Cell DAC and two M700 monoblocks. With t... 
The invention of measurements and perception
@kosst: "Unless you're telling me that those folks there can take their measurements and definitively tell the exact thoughts and feelings of a human being, you're not even close to understanding what I'm talking about."You give an inch and they t...

I couldn’t agree more, Geoff. I would just add that you also have to be willing to listen. 
The invention of measurements and perception
@kosst: "Any cognitive psychologist or neuroscientist will tell you that."Sorry buddy, but that’s simply not true. I worked as a postdoc in developmental genetics at U. Oregon in the Institute of Molecular Biology for three years and was very clos... 
Have speakers need new electronics
Discopete: I live in Medford; if you’re down this way in the near future, please stop by for a listen. My Thiel CS 2.4s drop to minimum 2.73 Ohms and stay below 4 Ohms for most of the frequency band. The PS Audio amps have no problem with that load. 
Is there an actual difference between AB and A/AB ?
Kosst: you can have push/pull Class A if the devices operate their 360 degrees of duty cycle out of phase of one another. 
Budget phono stage under $100, cheap but refined, does it exist?
+1 on the Schiit Mani. I have one, great phono stage at any price! 
Is there an actual difference between AB and A/AB ?
It’s simply the bias on the output devices that determines the level of power afforded in Class A. Such bias allows, or not, whether the output device can swing a given power level through the entire 360 degrees of the duty cycle. The limiting fac... 
Have speakers need new electronics
I highly recommend you try the 30-day, in-home demo of the Stellar Gain Cell DAC/preamp and S300 stereo amp, or their M700 monoblocks, from PS Audio. I recently purchased their GCD/M700 package, and, with a trade-in for my DAC, I paid less than $3...

@kosst:" In the strictest scientific sense, there is no such thing as music, or sound, or color, or hot or cold, or pain or pleasure."Do you even know what an enzyme is and what it does?In the strictest scientific sense, you’re way off base. I agr...

Why Power Cables Affect Sound
A few quotes from Lord Ernest Rutherford (1871-1937), one of my science heroes:"All science is either physics or stamp collecting.""An alleged scientific discovery has no merit unless it can be explained to a barmaid.""When we have found how the n... 
What are "true" balanced connectors
Balanced means that the + and - amplitudes of the signal are referenced equally to ground.

@mzkmxcv:  Sooo, what is your question now?
