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!

James at Legacy Audio here- I wanted to expound on some things 
for the community. The iV4 Ultra version dedicates the whole power supply of an 1200AS2 to supply the exceptionally high current capability. We have the iV amplifier on display in our CA showroom- Destination HiFi. We’ve been testing them thoroughly, here, and the dynamic range the iV amps provide offers huge benefits for all speakers. 

Additionally, when you look at the dynamic range capabilities of stereo source material (which is predominantly recorded at 24 bits) and the emergence of streaming high resolution two channel audio as well as Atmos surround sound, using an amplifier that can keep up with the dynamic range is increasingly beneficial. I invite anyone who wants to further understand the advantages of these incredible amps, to stop by and hear what they can do!


All the best,

James

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?

Hi twoleftears, happy to help.
The product you would be looking for is the iV2- it is a dual mono amplifier, that puts out 1,000 watts/channel at 4 ohms.

The iV4 is a four channel amp, and puts out 660 watts/channel at 4 ohms.

iV4 can be ordered as the iV4 ULTRA which dedicates a module for each channel. It is capable of 1,000 watts/channel at 4 ohms.

James.... Will you be at THE SHOW?

We won't be exhibiting at THE Show 2021 in a few weeks, but we look forward to continuing our attendance at future THE Shows. Legacy will be at AXPONA in the fall.
Anyone who would like to visit us in CA, is welcome to at Destination HiFi, where we have the iV amplifier as well as the entire Legacy speaker line on display.
