I don’t believe in magic. A 25W/ch amp no matter how good, will not reproduce large orchestral crescendi through an 89 dB speaker convincingly. If you have a superb tube preamp (you have!), you want a transparent amp with a large current capacity that can deliver into a 5 Ohm load. Dali designs their line to be benign loads… it’s a core tenet of their philosophy you can read in any of their white papers. If you are a he-man with a large budget, and no social conscience, get a Boulder, Soulution, or other similar over-engineered mammoth. If you prefer not to waste money or natural resources, get a Purifi Class D amp. NAD M23 is a starting point.
For classical music lovers best amp for large orchestral forces?
I recently upgraded my pre to an arc ref 6se. Currently using pas xa25. It's a very good amp but I'm noticing a fair amount of compression when playing large symphonic works. My speakers are Dalis and they are excellent as is the arc.
For smaller forces, chamber, piano and voices the system works beautifully. But if I'm looking for more transparency and a deeper sound stage for symphonies I find sometimes a boxy cramped sound. Looking to spend around 8k or less either tube or solid state. There have been discussions about the xa25 and what's better but they fill up immediately with tangents of philosophical and technical discussions of how one hears. I'm looking for as many possibilities of actual units that I can read about and possibly hear.
Thanks for your ideas.
