Okay I'm pretty newbie so bear with me here. I'm planning on building my first DIY speakers, probably the proac 2.5 clones due to the performance/cost/ease of build. I've read some reviews on the things and most people say that they only sound good on TUBE amps, which confuses me. I've always thought that the goal of Hi-Fi was to accurately reproduce music, therefore it would seem obvious to build a SS amp. Also I've always thought that TUBE amps "color" the music which some people claim to sound more "natural and warm." Why would I want to color the music if my main goal is to accurately reproduce it. So I'm confused...anyone want to clear this up? Have TUBE amps changed since I've last read about them??
