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.

plga,

Congratulations on the Nord. I too have the LM508IA and largely prefer it over the W4S ST-500 mkii class D. The W4S had great lows and mid bass but sterile mids and hard highs. Heck I even liked a 20 year old parasound HCA-1200ii better. I can see how a tube pre could work wonders instead of my DAC-2 pre on a class D amp.

What get's me is how much a positive difference quality room correction makes. How many commenting on Class D vs. A/B, SS, tubes have made these comps with room correction and separates? My experience was that class D was stark, bleached, just plain fatiguing. I'm sure a better/new class D amp would sound better. 

The exacting results of RC may have synergy with one amp and not another and knowing the differences RC makes, I never A/B compare without it. Could the Lyngdorf 2170 buzz be largely attributed to room correction?
