Class D Amplification Announcement

Class D is like Bluetooth or USB--a licensed technology that must adhere to certain standards and chipsets

This statement is 100% wrong and apparently poorly informed. Class D is nothing like Bluetooth or USB other than in someone’s mind apparently.

Class D is a design approach. Anyone can try and build one anyway they choose

It does often but not always involve popular modular designs or a board/component that can be used to build a complete amp product.

The reason certain modules are popular are because they are the product of a lot of modern technical innovations done well ( as a result of years of R&D) and therefore THEY ARE VERY GOOD ie they do the job very well and often for more modest cost.

Not to say everyone will choose them. That is never the case. Personal preferences always rule in the end. Some simply may not believe that technology always moves forward but in fact as a whole it always does.

Glad we cleared that one up. 😉

@pehare

Are you going to start a thread????????????

@pehare What tube amp were you comparing the Atmaspheres  to?

At what point do you guys say that your gear is "close enough" and start listening to music intentionally?

I have recordings I recorded and mastered. I was there at the musical event. I use these recordings for reference, since I was there. I recommend anyone who really wants to compare against the live performance to get a set of good mics and a decent recorder, then get out there and make recordings- very helpful for knowing what is right and what isn’t.

Once you get that part right then you can listen to other recordings on the same system to see how they are rendered. That is really the only way I’ve found to get at ’the absolute sound’.

Never any love for LKV on Audiogon.

For the voltage-gain circuitry, the PWR-3 uses a Class A, zero-feedback circuit designed by LKV’s Chief Designer Bill Hutchins. This circuit delivers life-like sound due to careful design and component matching, including 40 hand-matched, discrete jfets. For the high current output stage, Bill selected the Purifi 1et400A module, which implements Putzey’s breakthrough.
