How To Utilize A Phono Preamp Board As Stand Alone
Going to the local goodwill and finding a bi polar power supply wall wart. rare but they happen.Depends on the given outboard phono ..er.. board. Bose outboard power supplies were many times +/-18 VDC@1A, which is very nice. I grab them when I see... 
The invention of measurements and perception
Sure thing Geoff, got it. No one is perfect. I’m just rambling, looking for some projecting hornets nest to inflame itself and start poking at keyboards in anger. :p 
The invention of measurements and perception
I like to remind people that math is an excellent tool, but to remember that math exists no where in the known universe except as that - in a human’s head. Likened to an extra long perfect kinda stick for getting the ants at the bottom of a deeper... 
Is this the end of HEA?
CES is dying it’s a dealer show. Costs a fortune to attend...and everyone with a soul hates Vegas, no one wants to go there.Audio shows all over the world are thriving and growing. The death of CES for audio is tied to the growth of those other sh... 
Bright or Dim?
Lights off is very real and very physiological when it comes to attention paid via hearing. Human hearing is an alarm system which never sleeps. But it does vary in the brain power allocated to it.At night it can save your life, so when dark, it b... 
Sub recommendation to augment Klipsch La Scala's ???
You are getting into the area of ’the impossible match’ Horn loaded dynamic and fast bass, and trying to couple that with subs issue.Which is exactly where you are.... Tricky. Tricky at best ...and money and intelligence needs to be wisely paired ... 
Sub recommendation to augment Klipsch La Scala's ???
Fast and small, or like a fretless bass player, who wants speed and nimble in the box. That would be multiple or single 10’s in a single box. You need drivers that can go low, but still have a high acceleration factor (it’s a driver spec). This wi... 
All Kit are Band-Aids
In Canada, we have apparently asked for and received a 420 tuning.... 
All Kit are Band-Aids
So wake up and come to, however you can, or you’re not coming out the other side. And that story on the scientific proofing of the conflation of light and sound? There will be another story and report by the end of the day or next day, one as pote... 
All Kit are Band-Aids
The mid low 400’s in frequency do indeed cover a ultra critical range of wave vs particle behaviour. In either gas, fluids, or solids. eg, this is squarely in the center court of skin effect itself and as a manifestation. Skin effect in audio is g... 
Magnetic Footers
Not all good tweaks have to cost money. Generally the best don’t. How is that? Well, the best tweaks which are more ’intellect applied to the given scenario’ rather than ’expensive little bits of whatever’....are sought out by the manufacturers of... 
Am I the only one that finds the "Round thumbnail frames" irritating on classifieds?
We are designed to be resistant to change, yes. Part of our basic wiring. For better or for worse. Natural selection had it become ingrained into the design. Overall, probably a good thing, in most cases of natural world living. 
The Future of Audio Amplification
If GaN acts like a V-Fet or a SIT, then they might be on to something. The non linear gain curve of a modern transistor will generate odd order harmonics, which is where the problem in audio lies. A SIT or V-Fet, produces predominantly even order ... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
Prof uses the measurement canard which is as old as it gets and is well proven to be ineffective when it comes to human hearing at it's limits - which is the subject at hand. Interestingly enough, his entire job rides on doing things that are eith... 
Am I the only one that finds the "Round thumbnail frames" irritating on classifieds?
It is designed to make sellers pay more to get their message through to you. It’s not about your dislike, it’s about beating up sellers. It’s a forced shakedown of sellers, who have to pay more to get rid of the porthole view. The whole thing is v...
