MBL: single 9008A to drive 101e - bad idea?

I would really like to buy a set of MBL's (101E mk2 + a pair of 9008A's) but my budget is a bit tight for now so I am considering buying a single 9008A for now and adding to make a pair later on. I know that using a single 9008A in stereo mode is not a recommended setup because of the degradation in sound quality, but this is really all I can afford for now. Or is this a really bad idea?

Theses are my choices, any help would be greatly appreciated!

1. 101E mk2 + one 9008A + 1531CD + Denon AVR 3808 as preamp
2. 111F + pair of 9008A + 1531CD + Denon AVR 3808 as preamp
3. 111F + pair of 9007 + 1531CD + 6010 preamp
4. 111F + single 9008A + 1531CD + 6010 premap
or any other ideas?

Thanks so much!! =)

FYI My listening music is usually vocals and classical, and my listening setup will be in a pretty open space 5m wide x 12m deep
