digital Amp. Going green

What a dilemma, lots of conflicting opinions out there on gear and no way to hear any of them in Vancouver before I purchase. Then again I've bought all my gear that way and I have been very happy and probably very lucky. Any opinions about the halcro mc20 compared to the latest NuForce v9se 2. Remember, I have had a pair of Bel Canto EVo 200.2 and paired with the right tube Pre Amp they were very engaging.

Before I blow out my candle, how might it interact with the Galo Ref. 3s.

The above referring to Red Wine 70.2

Anyone looked into the life expectancy and cost for new batteries.

Ok, replaceable batteries but what happens when Red Wine Audio is no longer, lets say 5 years done the road. You have retired and because you were foolish and through what little hard earned money you had on this relentless habit, you can't be running out and dropping another $5000 on a new amp. Lets face it, it has to stop sometime. Will there be a replacement battery available? Call me paranoid, but that's exactly what happened to my Shanling SACD player. It stopped working and they will not fix it because they no longer make that model; It's only a year and a half years old! Are there any reassurances?

Thanks for everyones input.
