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.

John Atkinson got the following measurements for the Cary Audio SLI-100:

- 3.2 watts @ 1% distortion, into 8 ohms from the 8 ohm tap.

- 22 watts @ 3% distortion, same.

- 100 watts (Carys’ stated output for the amp) @ 10% distortion!

- 1.2 watts @ 1% distortion, into 4 ohms from the 8 ohm tap.

- Output impedance from the 8 ohm tap: 4.4 ohms @20Hz and 1kHz, 4.2 ohms @ 20kHz.

Retailing for $5995, that is very poor value. I would much rather own an Atma-Sphere S-30 or Music Reference RM-10 Mk.2.
