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!

Nice to hear from a fellow EVS1200 owner. In my experience it sounds significantly better without the Kubes and the top OFF. I bought a cheap AC filter to keep dust out. I also have Machina Dynamica springs for isolation. Also, PCs can make a big difference

The IceEdge modules are warrantied to an OEM as long as there are no mods to the modules (which is one reason most do not mod them), If a module goes bad then Icepower will replace any defective module for up to two years.  The modules are less than $300 each in quantity.  IceEdge modules are extremely reliable.

All modules that come from Ice, Hypex, Anaview, Purifi, Pascal, Powersoft, IR, etc.  are not designed for sonics.  The closest would be Purifi but I need to do mods to it to bring it up to serious levels.  We need designs by those that are super tweaky and are using the latest technology.  We now have GaN output transistors which seem to make a sonic improvement.....it is, however, just one factor among the infinite things in an amp that make better sound (in other words, all amps with GaN transistors will sound different from each other).  This is why this is an ever evolving game.  Some new from the ground up GaN developed amps are:

1. Premium-Audio 200 watt stereo for $699
2. Orchard Audo 150 watt mono blocks for $1500 and soon to be released 250 watt a channel amp...$2500?
3. LSA 200 watt a channel $3000.....says on the website to be released next month.
4. Mytek Manhattan dual mono 200 watt....$6K coming out this summer
5. Mytek Empire 500 watt mono amps....coming out in July $20K the pair
6. Java Hifi integrated amp ....starts at $8900
7. 85 watt mono AGD Audion Amps....$7500 the pair
8. Merrill Audio amps $16K-$38K
9. AGD Gran Vivachi mono blocks....$18k.
10. Technics integrated....10K and older stereo amp...$18k
11. Atmasphere stereo amp.....$5k?...later this year.

This is just the beginning.  Lots of cool stuff coming down the road.

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.

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.
