AR might be in the mix, but I am pretty sure PS Audio opened the door decades ago.
The Future of Audio Amplification
I have recently paired an Audio Research DS225 Class D amplifier with an Audio Research tube preamplifier (SP8 mkii). I cannot believe how wonderful and lifelike my music sounds. The DS225 replaced an Audio Research SD135 Class AB amplifier. Perhaps the SD135 is just not as good as some of the better quality amps that are out there, but it got me thinking that amazingly wonderful sonance can be achieved with a tubed pre and Class D amp. I have a hunch that as more people experience this combination, it will likely catch on and become the future path of many, if not most audiophile systems. It is interesting that Audio Research has been at the forefront of this development.

Reading a class D review (6moons/Nord Ice?) the reviewer mentioned power cord sensitivity as an issue. Several months ago I replaced a wireworld series 7 PC (MSRP $300) with a boutique $800 PC which sounded significantly richer And just a week ago I went from toslink to a prototype coax (not at liberty to say until production). Last night, listening to Ray Charles Duets was amazing Oh, my amp is Audio Alchemy DPA 1 |
