Congo,
There are very few combinations like that out there. Micpres and compressors are somewhat different entities, and they do not often come in the same box.
Unless you're buying a complete recording channel.
And even few'er of those are stereo devices.
I think you'd be better off buying two boxes; one dual micamp and one stereo compressor.
If you buy to independent mono micpre/comp units, you may have trouble getting the compressors tracking for stereo..
We manufacture and sell tube devices like the mentioned (in Denmark), and on our webpage there is details of these types of units..
Best regards,
