AGD Vivace GaN Gallium Nitride

Thoughts on this technology? Class D;

AGD PRODUCTION

How are cooled the active elements in the vacuum tube?
What's the meaning of this?

Noise floor is -110dB. 2nd harmonic is -112dB and 3rd is 110dB. Nothing out of the ordinary except he is using GaN-FET, which could be a TI or Infeneon product. US $15,000/set (2 mono blocks) - 100/200W in 8/4 ohm load.

Whenever a marketing text claims something "mystical" about their product my alarm bells rings.

 

[Oneminde]

Not only that, they make a big thing about the output stage being in a glass envelope. "Because it looks like a KT88 tube it probably sounds like one"

 

[jean-paul]

Marketing-wise this has been well thought out!

 

[Oneminde]

Out of curiosity, which part ?

 

[jean-paul]

Surfing the Class D hype and at the same type pleasing the tube crowd. It is surprising that the manufacturer does not mention the eco/green aspect of this technology, it would maybe attract "save the earth" people.

Claiming it being "The Most Advanced Power Amplifier Design in Hi-End Audio" is somewhat ambitious though

ROFL ... For some there is no limit to how much they can brag, true or not does not matter.

 

[Guerilla]

Could be it sounds great. Maybe its just what many people's speakers are missing. No reason to sell it for 400 $ if you can convince some people to pay 15000

 

[Oneminde]

I'd rather take NAD M22V2 or the Benchmark AHB2 which is $3700 each.

2 x 200W for USD 15K?? LOOL what a BS!!

the 200W is in 4ohm, which makes it a 100W in 8ohm (roughly).

There are essentially 4 class D amps on the consumer market that pass the eye of the needle and they are NAD M22 (Hypex) and NAD C388, Benchmark AHB2 (THX/AAA) and Mytek Brooklyn (Pascal). I know the newer ICE modules are supposedly to be much better, but see no need to investigate then.

More curious on the technical side of things.

Power is the easy part.

Also - AHB2 is AB, not D
