The 550ax is actually a pure Class A design, so it does not transition to AB...maxes our at 40W into 4 ohms.
Luxman L-550ax
Hi,
I have just bought a Luxman L-550ax. I bought it for the reason of eventually relocating to a smaller place and need an all in one. Due to that relocation, I will eventually need to get bookshelf speakers. I've narrowed it down to the Ascilabs C6B. They are 85db at 4 ohm. Will the 550ax's 40w class A be able to drive them in no larger of a room than 15' x 20' ?
Thanks for the help
