Default Multi-amping Troels Gravesen's OBL-11


I am building Troels' OBL11 (OBL11), and recently the multi-amping idea arised in my mind. Since the speaker is fairly efficient (ca 95dB), the required power should be managable. Troels' comment on powering OBL-11:

Can the OBL-11 be driven from your 8 wpc 300B amp? Yes, if you don't play particularly loud. Does the Audio Mirror 20 wpc amps sound more dynamic? Yes. Does the Jungson amp - 80 wpc - really kick butt? Yes!
I will be using a DSP based crossover with one DAC per amp (for a 3-way: 6 DACs, based on the T-DAC design (RPi-DAC - Dual Mono)), so the last part that needs to be figured out are the amps.

I have been studying various approaches, but before I start rambling with my own half-done ideas, I'd like to ask what would you guys (and girls) suggest.

So, the question is:
how would you choose the amps for this particular application?

Cost can be regarded as a secondary constraint, but the solution should be DIY, based on commercially available components.

Primary objective is best possible sound (dynamic range/SNR/THD), and the deterministic use case (it is known that the amp is driving a single, predefined chassis).

I'm looking forward to new ideas!
