Infinity Renaissance 90 questions

Hi fellow AG'ers, I have just pulled the trigger & purchased a pair of Ren 90's in black ash & had some newbie questions for more experienced members. Firstly as they are still shipping from the US, I'd love to know what finish (Black ash or blonde oak) you prefer? In my case, a micky mouse pair came up for sale at the right price in Black ash, so I grabbed them..

Also, I will be initially running my Rens with a Classe Cap-2100 integrated amp which has been bench tested at 235watts/4 ohms. I know most punters advocate giving them 400 watts per channel, so what do you think? (although the Classe has a truckload of current to compensate). I should mention I plan on upgrading to a Ca-2200 pa & AR Reference 3 in a few years, but for now, the Cap will doing regular duties.

Finally, I would be interested to hear from any members who have re-wired their Rens & had a high-end external crossover built & what results you got? I am planning a very high end x-over mod & re-wire of my Rens with Acoustic Zen wire next year and would appreciate any suggestions.

Cheers!
