Hi faust,
I've been busy exploring the tube world, sorry just catching up now. I honestly think Contour is outclassed by D3, but I'm surprised how expense it is over in Taiwan. I think your Taiwan price tag comes out over $10,000 USD. Contour 30 is only about $7,500 here. Though to be fair, your poor demo experience is likely due to poor choice of the Audiolab mono-block amplifier. It's 8ohm (250W) to 4ohm (350W) power ratio is only x1.4 and doesn't even do 2ohm.
I agree with the store's opinion that new speakers are going the high resolution route. I'm feeling a bit stupid with the D3 as pairing the D3 with very good tube gives similar sonic quality to the old S with very good solid state. Here's my dilemma, these new high resolution speakers in theory would work well with SET tube amplifier but they are also current/power hungry so I find using low 8-10W SET amplifier the sound comes out thin. If I use tube push pull amplifier that produce 40-60W, the sound is very similar to good solid state that there's little incentive to go with tube (maybe tube rolling will change my mind). So in the end, I might just have to give in and buy a Mcintosh that has the solid state current/power with tube lush warm holographic sound. sigh, money money money...
