Class D amps that are superior to all or most?


Recently, I have heard about some Class D amps that may be close to the best there is regardless of class. Certainly, this technology has been in development for decades. The main issue has always been the switching power supply. In this regard, I have taken notice of AGD. They have created a whole new power supply that “switches” at a frequency 100 times the normal silicon based MOSFET. The designer uses a gallium nitride based PS. Interesting, it is enclosed in the KT88 glass envelope that sits on top of his amps. I am aware of two more pricey amps that seem to be also at the top- the Solution and the Merrill. There must be others that compete for the title. After my thread, “Is there a SS amp that can satisfy a SET guy?”, I am still on the quest.
Don’t want to spend $50K!

... it’s time for you to reveal your industry affiliation ... You say go
to your website? Really? No name, no company name, no direction? ... I tire quickly of foolishness From
my perspective as a reviewer, this is not going well for you ... Frankly, this is beginning to look pretty ugly. You have a chance to clean it up.
Such righteous indignation! It took me less than 1 minute to figure out that Ric is Electronic Visionary Systems. I’m sure Doug would have found the same info if he’d tried.


Doug,
You are making a mountain out of a mole hill.  You stated something in your review that made no sense to me.....the bridging thing.  So, I asked you where you got that information.  Then you repeated the same information, that to me, still makes no sense.  I showed you the insides of your amp and that it shows no hookups to one channel of each board.  I am interested in TRUTH.  Are you?  If you want to find out what is really going on in the amp (to back up what you think is going on) then all you have to do is take off the cover of the amp and take a good look inside and see if I am right or wrong.  It is either a stereo module using just one channel (what I think it is, again, I could be wrong) or it is some weird way to hook up two bridged channels together that I have never heard of.

I am semi retired.  I make practically nothing.  I don't have products to protect.  In fact, if I were still selling my IceEdge moduled amp I would remove the coverings of my mods to the board and let everyone see every single thing I do.  No one would be tweaky enough to even copy me.  What I do is not financially viable to run a company.  What I do is far to tweaky and time consuming.   I am mostly an enthusiast who is a crazy tweaker.  I love to turn people on to really good gear that costs very little.  I mostly love to teach people how to fully live in the moment......in the love and joy we really are.

I am sorry you feel threatened by my inquiry.  I only want the truth to be told.  Please follow up and show us the truth.  We are all ignorant.  No one knows everything.  We all make mistakes, we all assume things and tell others and then realize later that we were wrong.  We are all bozos on the buss. However, we are all divine and beautiful.  We can correct our mistakes.  We can forgive ourselves and others.  A sense of humor is always the great healer.  Lighten up, oh beautiful one.
Ric, I really appreciate your last post! Cleeds’ post enlightened me to the fact that I did not see the disclosure of "ricevs", as I am not familiar with your company. I removed my two previous posts, as I now consider them unproductive to continued discourse.

I also want the truth, which is what I was probing for in those posts. I do not have the topological answers you seek; you would need to discuss with Legacy Audio.

I mean no offense when I state that no one can tell whether a modded component from any modder would sound better than any given stock component from another manufacturer. I do understand you comment about all components being modded. I have compared a fair number of tweaked/modded products, and I have found no direct correlation between modding being universally superior to any other given stock component. That is why I state one simply has to make comparison. Others may have different experience, but that has been my experience.

In reply to your comment, "What I do is not financially viable to run a company," you are not alone. I have heard similar several times from other manufacturers.
I'm still confused.  Legacy makes a whole family of these amps, from the Legacy i-V1 through to the i-V8, offering one through eight channels of amplification.  Can the i-V4 be bridged to 2-channel output?  Or?
This is what I think.  Legacy buys stereo modules.  They use them in all the amps.  So, an i-v8 would have 4 stereo modules (8 channels).  The regular i-v4 has two stereo modules (4 channels).  The I-v4 ultra has 4 stereo modules (8 possible channels) but they use just one channel of each module so they are basically mono amps.  This gives more power for each channel and zero cross talk.  Each channel is already bridged, so you cannot bridge an already bridged amp.  So, no the i-v4 ultra cannot be bridged in any way.  It already has 1200 watts into 4 ohms on each of its 4 channels.  How much power do you need?  I believe the i-v2 dual mono stereo amp has 2 stereo amps and then just uses one channel of each amp to make it mono.
