Are monoblocks better than stereo, with tube amps?


I am only in the research phase of audiophilia. My present system includes a creaky NAD 150w amp and ghastly sounding speakers from a "rack system" circa 1988 Stalingrad. Anyway, I am hoping to eventually save for a tube set-up with a kind turntable and sweet, costly speakers. I am wondering if there is any advantage to using a monoblock system for amplification and why.

I love monoblocks. They typically have double the power supply than a stereo amp which gives them great authority and the feeling of more power even if on paper they are the same.

They also have no crosstalk between channels. I think this advantage is bigger than many give it credit for. Imaging improves greatly with no crosstalk or intermodulation distortion. So does the "space" in a soundstage.

IMO, it is worth the extra money over the stereo version. Good luck and have fun. Arthur
As above I agree, they are not really rated at higher output but cleaner and more balanced due to the increased power supplies, mainly bigger transformers dedicated to each channel and they don't get to close to power saturation sharing everything with two loads on 2 speakers, opposed to a single load, and normally more than likely an increase in capacitance filtering as well... With tubes especially I could see how this would benefit being a lower noise ratio.
Manufacturers of high quality components equip their stereo amplifiers with sufficiently large enough power supplies to make it a non-issue.

I would be far more concerned with design, parts, and build quality.
