Default DIY amp for bi-amped 2-way horns?

I am gearing up for my first DIY amp project. The overall project is to bi-amp (after the crossover) a pair of high-efficiency speakers. These will be two-way horns (folded bass horn & tractrix HF). Their efficiency will be about 107 dB/watt & and will not present an impedance below about 5 Ohm.

So I do not need loads of current or power but the signal needs to be quite clean. In terms of the audio "lingo" I am after "accuracy" (especially a solid & tight bass) not "warmth and lushness".

My current candidates include 1) Leach and 2) Pass - Alpeh.

Your thoughts & wisdom are appreciated.

with 107db/W you can manage with just a watt or two.

If you want to listen very loud then 10W to 20W.

This seems to keep you in the ClassA league, either push pull or single ended.

You do not need Leach ClassAB 120W+

The efficiency certainly eases the power requirements. I would be probably be going for about 20 watts (max) so Class A would be a great candidate. That is why I listed a smallish Pass design.

Since the speakers are quite revelaing (and I love an accurate sound), I was intrigued by the low TIM designs. That is why I put the Leach amp on my list.
