I'm from the other school: I want my gear as small as possible, if commensurate with sound quality, and if needed, power. Minimalism — if it were possible my gear would be invisible, the music would just "be in the room". Of course I'll make exceptions if a component is truly exceptional — I once passed on a 100V Denon receiver because it was huge, but everything about it reeked of quality; the vents allowed a good view inside, the component-quality and layout were stunning, preamp/power amp/tuner sections were really separates with independent power supplies, sharing only the casework and on/off switch. It was clearly High End exclusively for Japanese audiophiles ... I still lose sleep over that bad decision.
And speakers are always an exception — I have some highly esteemed 2-way monitors with stunning nuance and imaging, but I just can't resign myself to their "small sound". Subwoofers don't really help, they only produce "small sound with bass."
