I could be wrong, but I doubt Crutchfield sells to Colombia.
As far as solid state with HD800 under $1000 (to fit with Concero $600) I haven't heard anything I would say is as good as the CSP2+, not even close. The Mjolnir is a good option on a budget, but if you can handle tubes, the CSP2+ is significantly better for the extra price. Otherwise I would say go with a Matrix M-Stage HPA-2 (~$280) and save your pennies for eventual Headamp GS-X 2 (~$2800), the only high end solid state that can hang with tube amps (have not heard Cavalli Liquid Gold, but at $6500, it's well beyond my limit). Concero + HPA-2 if you must go solid state. The Concero HP is a good alternative for slightly worse sound in a microscopic package size and it is a little cheaper than the Concero + HPA-2 combo.
I have a shipping address in the U.S. so delivery wouldn't be a problem. The issue for me is I can not sample any gear before buying it, so I must make the decision blindfolded so to speak, and can not afford to make the wrong one. This is quite an expensive hobby.
Tube sound I'm not entirely convinced I'll like. SS I know and like.
Another thing is, I only listen to music at very moderate volumes. Is this a factor to consider when determining how much to spend on an amp? Maybe the money could be best allocated on a better DAC?
