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.

Typical of kalali to slur, when can't understand, he can’t see the forest through the trees.

FYI, Class D is NOT digital, it is analog all the way through. There are no zeros and ones.

Class D is analog, but the output is switched, so IMHO it's arguable to say there are no zeroes and one's. There are, in the output stage. However, the control of that switching state is purely analog.

There are also some amps like the latest Technics SE-R1, which are true digital amplifiers in that they convert everything from Analog to Digital, allow for phase and amplitude correction in the digital domain, and then produce an output based on a PWM output stage.

That’s very rich coming from a "fuser", water off a ducks back coming from the likes of you.
" I have both Black and Blue fuses and prefer the blue overall. It was easy to tell which fuses were stock as the difference is so great
The fuse change was especially easy with the Blue fuse sounding better immediately versus the 72 hour break-in period for the Black.
Get the Blue fuse and enjoy better music without the wait. The SR Blue fuse sounded great right away while the SR Black took 72 long hours to achieve it’s great sound. I’m so happy to pay only $20 more for a ready to use fuse."

What a load of ****
