I've listened to Balabo equipment for quite a period of time in the recent past. They are big, heavy, have a lot of parts in them, and never ever sounded offensive to me.
The power amp sounds like an improved Forsell Statement amplifier. Dark, sweet, just plain easy to listen to. For my own tastes, the top three power amps today would be the FM Acoustic 1811, Lamm ML 3 and Balabo.
The line stage is the most complex of its kind that I have come across. When I lifted the top cover, the complexity of the volume control alone is a sight to marvel at. This component very naturally brings forth the beauty of a performance. There is simply more body, more bloom and more reach into the listening area when this component is inserted. Just for the heck of it, I once set up a chain composed of the Spectral cd player, the Balabo line stage, the 47 lab gaincard, and the Magico V3 speakers. The sound was so un-fatiguing I listened until the shop had to close.
When one puts together the line stage and the power amp, to get the best sound, one has to use one of three grounding cables that runs from the linestage to the power amp that Balabo offers. One will have to experiment on these three grounding cables as they significantly alter the sonics. The best combination of cabling that I have heard for the Balabos are MIT Oracle interconnects between the line stage and the power amp; and, Sensory Power speaker cables between the power amp and the speakers.
