Someone convinced me to refoam a pair of 127A's for him, and to extra motivate me he also brought a stereo tube amp that I got lent for a week or two.
It's a Mastersound 845 compact made in Italy, he is the german distributor, and it has approx. 10x the value of the L166's that I'm currently using to try it out. So far, so good – sounds wonderful, but I consider to try it also in my bi-amp setup for the MF/HF/UHF part of the 4343's, because it has a power amp only mode.
My question is, how much translate 20W Class A (thats what he said it has, the website states even 30W Class A, probably at 4 ohms) – in normal output watts? Probably suffice to run the upper part of the 4343's I'd think, compared to the 150W/ch at 8 ohm Citation 16 for the LF part?
Is there a rule of thumb for that? Thanks.
