Toch nog even wat heen en weer gemaild met Finalé Audio ivm wat meer info wat de speaker nou eigenlijk doet op een buizenversterker.

Hi Niek,
In general, the best tube design is a more linear output device than transistor. With small full range drivers like the Mini, this is noticeable in that solid state amps just don't sound smooth enough. It's hard to explain this in objective terms. But be assured, the Mini was designed and voiced with single-ended and paralleled tubes (2A3 triode).
Best regards,

Hi Niek,
You can drive them with an 8 Ohm amp, that's ok.
A 16 Ohm full range driver like is used in the Mini is designed to be extremely easy to drive:
- no crossover network
- the high impedance is friendly to tubes
- the driver's Thiele-Small parameters (Qts in particular) make it more efficient than the "consumer specs" suggest: the driver has sympathetic damping so it requires very little current from the amp
All this is to say that yes, you can drive the Mini easily with a few tube watts, it behaves more like 96-97dB than 92. I wouldn't hesitate to use a good 2A3 SET - at least in a modest size room, with most music.
Note that tube amplifiers usually have output transformers with multiple secondary taps - with Finalé amps for example, there is almost always a 4, 8 and 16 secondary in the transformer. We often connect only two of them, to keep the chassis (and circuit) cleaner. But there is usually a third option available, which may be a custom request.
Hope this helps,
Ben nu toch voorzichtig aan het rondkijken naar een buizenversterker en of dit nu qua kosten een beetje kan. Hun eigen amps zijn een beetje kostbaar.
