Impedance Matching

  Quote: Originally Posted by mamba315    Now, my question would be whether it is common practice for manufacturers to include a buffer on headphone amps before the gain section.  Is it always done, or is it sometimes done and sometimes not?  Could this be why some amps receive wildly different reviews, or is "synergy" and "taste" still the most likely culprit?     This is an interesting question, but requires a little thought about the nature of impedence and AC signals.   Unfortunately, it's not quite as simple as just adding a... read more

What Makes An Audiophile

I thought this was incredibly well said, so I'm putting it here: Quote: Originally Posted by PANGES  In my opinion, an audiophile is anyone who can appreciate sound quality. Isn't that really why we're here in the first place? To find headphones that have the particular sound quality that best suits our tastes?   By definition, the word audiophile: audio refers to sound and phile refers to love or being passionate for. So if you're an audiophile, you should just love sound or appreciate good sound quality.    I personally don't... read more

Paypal Friend Or Foe

    PayPal erupted on the scene many years ago as a new way to get paid for purchasing goods on the internet. It was a revolutionary idea whose time had come. It was a service that many of us had wished that we had especially when we were selling goods on the internet. We would have to wait for personal check to clear and also for the money orders to arrive. It would slow our buying and selling process down by waiting and buyers backing out and the insecurity of when you bought something you paid for with a money order or a personal check always wondering if the... read more

Syncing music and making playlists work with the Astell & Kern AK100 and a Mac

  I figured out how to create playlists on my Mac and put them on the AK100. It's a bit of a PITA but it works.   First, I use Markspace Android Sync to copy the iTunes playlists and music I want to my micro SD card. I first set that up to tell it the types of files that can be played, as the default doesn't include m4a, and others. This re-creates the playlists in a folder/directory named Markspace/Playlists on the SD card and puts the music in Markspace/Music.  I open up those playlists in BBEdit and change the paths from "../Music" to "/mnt/SD0/Music" (Note!... read more

Blame It On The Game An In Depth Interview With Fab From Milli Vanilli

An insider’s look at the Milli Vanilli project When the Milli Vanilli lip-synching controversy broke in 1990, I was not surprised. Nor did I really care.  I wasn’t a fan of their music and I had no idea about how the music industry really worked. I believed what I read and saw. And with time, Milli Vanilli completely dropped off of my cultural radar. So it was. Life moved on. Eventually I found myself working in the music industry. Things are not what they always appear to be. Smoke has its mirrors and in the end, people will believe whatever gets broadcast the... read more

What is The Correct Way To Turn On Tube Amps With Headphones

Speaking of contacting the manufacturers, I got a response back from Jack of Woo Audio. I want to thank Jack for getting back to me in a timely manner and taking time to answer my questions. Anyways, here's his response to my questions regarding WA6: 1) What's the proper way to turn on WA6 with headphones? I ask this because I've read some stuff about it being harmful to the tube amp to turn it on without headphones in? Is this true? So far, I've turned on the WA6 without any headphones inserted (when I turn it on with headphones in, it gives the loud startup tube hum... read more
