Well, it is very obvious what MiniMe needs. The speaker is begging for multiamping. The speaker has 2 distinctly different sections. The HF section has 4-5db higher sensitivity and SET friendly. The LF section needs 100W of output impedance that deal with port’s current sinking, Sure it shell be SET/SS multiamped. I did try it to drive like his last night and it was almost tolerable. I did not play with SS bias and port setting on bass section but it was clear that 100W was the direction to go. What suck in all this business that multiamping is fundamentally against the whole MiniMe idea. The MiniMe have to be cheap, simple and none-demanding. OK, I have blown the cheap part but the rest I would like to maintain. Theoretically if I found a cool-running 100W amp that would do OK on MiniMe’s HF channels then I would be fine but from what I feel that time of amps would be a large “class A” amp and I am not going here. Alternative would be to use the a little SET with some kind of very small A/B sub 500Hz bass amp, perhaps even class D amp, even if I doubt. I would like to have all of it cool-running and be managed by a single switch.
BTW, here is another situation where there is very clear and rational need for a product but the industry does not offer anything. There are huge numbers of speakers that are built in the MiniMe configuration – separate LF and MF section – Verity, Wilson and many-many others. It would be so good to have a dedicated bi-amplifier for them. Something not expensive – $2K-$3K, that has aboard a cheap DSET for MF/HF and a high current A/B class SS amp. If everything is arranged in a small and convenient packaged, supplemented with a reasonable 4-wire speaker cable then here is a ready to fly from the shelf product. I think if it doe properly then this “combined” amp might be very successful tool. The freaks out there you are in the industry take a note.
