The original UCD module had lots of feedback.....all around the output coil....The Ncore modules added even more feedback and the Purifi adds even more feedback.  Most people feel the Ncore sounds better than UCD and Purifi sound better than Ncore...

The Levinson amp switches at 2Meg and it sounds bad.  For what reason?........who cares.  You buy it, you lose.  The AGD amp switches at 500K.....it sounds good.   For what reasons?......who cares.  You buy it, you grin.  End of story.....Everythi...

Of course, I checked every channel of every amp that I sold and looked at the residual of each channel. I just did not do an exact measurement of the before and after. From what I remember, it was very much the same, about a half a volt or so of p...

Trouble is the Levinson sounded like crap.  Everything makes a difference....again....the truth is in the listening.  It does not matter that Levinson used a bunch of air core coils (one thing does not make a whole).......what matters is the sound... 
Class D
Because the filter is set at 50K does not mean it does not effect the sound.  It's intrinsic sound is still there.  No free lunch.  Everything makes a difference.  But you have to listen to know.  Years ago I worked for an audiophile company that ...

You can theorize all you want. What I do is listen. Most EVERYONE who has listened to ferrite core coils in a xover.....knows they suck. I now know they also suck as "full range" coils on the output of a class D amp. You can only know how somethin...

I did not measure the amount of residual after removing the secondary coil and caps.  Since the caps to ground were just 1000 pf....I imagine that the residual looked much the same.  IcePower was probably trying to remove ultra high frequency nois...

Here is an interesting fact. The IceEdge module has two....yes, two inductors in series on the output. It could be one reason the phase does not measure so well. I removed the last inductor and the last set of caps to ground as part of the last se...

Here are some interesting developments....1. Class D audio (under the Premium Audio name) will soon be releasing their "baby" GaN amp.......stereo, 150 watts a channel into 8 ohms, balanced and unbalanced inputs for a mere $699.  100K input impeda...

Please don't be stupid.  It is stupid to respond to George.....he is a rock....he will never move from his position.....and he has to have the last word.......so it will always go on and on and on.  Don't be stupid....he does not want to learn.......

Douglas,I hope this tease of yours dies quickly.......What is this mysterious class D amp that you love?  Is your mouth tied shut till the review?  he he....If you absolutely cannot tell us more.....then when is the review going to be published?

MCHave you changed all the xover parts to way, way better ones?......and better wire and removed the binding posts.....and mounted the xover externally?  You will get a whole nuther level of transparency if you do this.  Felting around all the twe... 
My Long List of Amplifiers and My Personal Review of Each!
annoying equals......something wrong.  Try choosing again.....go for the happiness......wish me well.Do you like being annoyed?  Why would you choose that experience?  When you point a finger at someone, there are three pointing back at you.  When... 
Purifi Class D: Junk?
You say there is nothing wrong with it and at the same time you say there is a "massive improvement"  when you bypass it.  You cannot have it both ways.  Every op amp....every regulator......every everything....has a sound.  So all buffers, etc wi... 
Purifi Class D: Junk?
"I don't get why Purifi thought this thing sounded good enough to release to the public"  What are you talking about?  You are not hearing a Purifi.....you are hearing a Purifi with a Hypex buffer put together by VTV.....The Purifi can use any buf...
