Class D Amplification Announcement

Michael Borresen is one sharp guy and it still amazes that he can design world-class speakers, and then go into amplifiers and other items as well. Prior Aavik pieces seem well-regarded (despite the prices of all Borresen designed items).    And then there is the obscene pricing for sn... oil products...

I have DSP room correction and minor DSP equalization and my good old McCormack DNA-1 as musical as it is, cannot hold a candle to my Class D W4S STI-1000. 

The W4S Class D integrated is silent at the speakers and runs 500w/1000w which is plenty for the old Raidho D2s. I get pure liquid detail and an iron grip on bass. I've never had a super expensive Cl A or AB to compare, but I am very happy now.

If you read it, it MUST be true.

The reason why I think more manufacturers will be using their resources in developing Digital and even lower cost Class D amps is in part due to the energy efficiency.

The reason we did it is because the switching nature of the class allows the designer to be freed from a lot of the distortion sources that cause solid state (AB designs) to sound bright and harsh. In that regard, the same reason we've made tube amps for the last 49 years.

Ralph, could this have been possible without the GAN ? If so, why wait so long ?

@jjss49 Yes, I definitely intend to reach out to Alberto when I’m close to making a decision. The problem is that currently I have an integrated amp (Audio Hungary Qualiton a50i), so getting an AGD amp can only happen after I have also acquired a preamp. From what I understand, I cannot use my Qualiton purely as a preamp. If I’m mistaken, feel free to correct me. Also, if I do get a preamp most likely it will be tube-based. I don't want to be too adventurous :) Baby steps! 

Second problem is that my current setup (Qualiton a50i + Joseph Audio Perspective2) is sounding so great that I don’t know if I want to change anything. I finally dialed in the subs perfectly, and to be honest, this is by far the best my system has performed. Not to say there is no further room for improvement. But I just don’t want to make a lateral move. But what I do know is that whenever the itch gets out of control, AGD will be top of the list. I really appreciate your input.
