Do we really need amplifiers with 100watts per channel?

[QUOTE="chipwelder, post: 1784, member: 54"] I totally agree with statements above... The big sound and cool bass comes from the PSU... amps of similar descriptions can almost be rated by the weight of PSU and the filtering of it... The CA does tend to have better PSU than normal - at the expense of millions of features... even the old A3i I had, had much more "power" than the comparably rated integrateds... That's why I have six gainclones for two speakers... plus 80000uF of capacitance... and 300VA transformer - which technically should be doubled to be able to give all the chips all of the juice - when playing into four ohms :D If you want big sound from a chip-amp, go big on the PSU... it (LM3886) will almost double from (8ohm) 38 watts to (4ohm) 68watts, if you have enough VA and heatsinks behind it... Around 100VA per chip is great, most people get away with 80 with no hassle... [/QUOTE]
